The hike is rarely the hard part β the lot is. Each guide below covers one trailhead: how many cars actually fit, when it fills on a weekend, what goes on the dash, the tow/citation risk of getting creative, and the realistic plan B. Pass rules change completely between regions β the Adventure Pass covers most national-forest trailheads in the San Bernardinos and San Gabriels, but buys nothing at San Diego's state, county and city lots, and nothing in national or state parks where an entrance pass, shuttle, permit or timed reservation controls the approach.
~8β10 spaces for the most Instagrammed trail in the range. Full by 9am on spring weekends; no sanctioned overflow.
Details, fees & parking βTwo ways in: Bowen Ranch's dirt lot ($10/person cash, rough road) or free, limited roadside at Bradford Ridge off Hwy 173.
Details, fees & parking βSmall primitive lot on Keller Peak Rd off Hwy 18. Adventure Pass required β and check fire-closure status first.
Details, fees & parking βThe rare easy one: paved lot right off Hwy 18, rarely fills, vault restrooms. Adventure Pass still required.
Details, fees & parking βNo real lot: informal dirt pullouts off Hwy 173 near the OHV staging area. No facilities, no signage β download maps first.
Details, fees & parking βOne trailhead, two trails: North Shore Rec Trail and Little Bear Creek both start by the campground on Hospital Rd. Rarely full.
Details, fees & parking βBig Bear's most popular trail got a real lot in 2025: 38 free paved spaces, 7amβ7pm. Still full by 9am on summer weekends.
Details, fees & parking β10β15 spaces for a PCT gateway trail, full by 8:30am β but there's a free 50-space plan B a 0.6-mile flat walk away.
Details, fees & parking βFree 50+ space lot, real restrooms, sells Adventure Passes β and a paved path to the Cougar Crest trailhead. The north shore's easy button.
Details, fees & parking β20β30 spaces at a proper picnic area, rarely full before 9am. Adventure Pass on the dash and you're hiking to Grand View Point.
Details, fees & parking βSan Gorgonio's front door: Adventure Pass + an online-only wilderness permit, a lot shared with waterfall tourists β and a free official overflow at Momyer.
Details, fees & parking βBig Bear's easy 1.5-mile family nature loop. Small Adventure Pass lot on North Shore Drive β but the free Discovery Center lot is right next door.
Details, fees & parking βThe biggest lodgepole pine in the world, reached by a dirt-road drive. Small Adventure Pass lot; the real question is the road, not the walk.
Details, fees & parking βQuiet, less-crowded Big Bear summit hike with a flush toilet at the trailhead. $5 day pass or Adventure Pass β but it's closed roughly Nov 1βApr 1 (into July in 2026) for bald eagle nesting. Check the closure before you drive.
Details, fees & parking βThe long climb to San Bernardino Peak from Angelus Oaks. Adventure Pass to park, plus a free but quota-limited San Gorgonio Wilderness permit you must reserve online ahead of time. ~20-car dirt lot at the end of a rough road.
Details, fees & parking βOpen 24 hours, vault toilet, Adventure Pass required β and not sold anywhere near the lot. Hikers report arriving before 8am on weekends.
Details, fees & parking βOpen again after two fire closures. Gate 6amβ8pm, lots gone before sunrise on weekends, and the Mt. Wilson side is still closed through 2027.
Details, fees & parking βSmall upper lot at the highway, bigger lower lot down a gated spur. Be there before 7am on weekends or you're walking the spur road.
Details, fees & parking βTwo pieces of paper, two agencies. Adventure Pass to park, free wilderness permit to hike β and which permit depends on which peak.
Details, fees & parking βThe launch point for San Antonio Falls and Mt. Baldy's summit. Roadside parking fills by 7am on weekends; the pass rule is genuinely muddy β here's the honest read.
Details, fees & parking βClosed through Dec 31, 2027 after the Eaton Fire. The free Nature Center lot off Altadena Drive is closed with it. Here's the status and the parking picture for when it returns.
Details, fees & parking βClosed through Dec 31, 2027 after the Eaton Fire. Parking was free residential street parking at Lake & Loma Alta β here's the status and the reopening picture.
Details, fees & parking βThe lower Sierra Madre trail reopened in 2026 (free street parking at Mira Monte) β but the upper trail and the Altadena-side Toll Road stay closed under the Eaton Fire order. Here's exactly what's open.
Details, fees & parking βStart of the Mt. Baden-Powell PCT climb. The paved lot is now concession-run and needs a $5/day Big Pines Parking Pass β Adventure Pass no longer accepted β but roadside parking on ACH is free.
Details, fees & parking βDramatic tilted-rock canyon on the desert side of the San Gabriels. Free LA County lot with a nature center and restrooms β no Adventure Pass. Closed Mondays, ~30β40 spaces that fill on busy days.
Details, fees & parking βThe most rule-stacked trailhead we cover: Adventure Pass to park, a free wilderness permit to hike, a 30/day summer weekend quota β and real towing on Fern Valley Rd.
Details, fees & parking βIdyllwild's gateway to Suicide Rock and San Jacinto Peak. Two pieces of paper needed β an Adventure Pass to park and a free wilderness permit to hike β plus a small lot that fills early.
Details, fees & parking βThe shortest route up San Jacinto Peak. Free dirt lot off the campground road β no Adventure Pass needed here β but you still need a free wilderness permit, and no dogs.
Details, fees & parking βThe quieter route to Tahquitz Peak's fire lookout. Adventure Pass to park, free wilderness permit to hike β but rough dirt Road 5S11 means most cars park low and walk up. Compares to Humber Park.
Details, fees & parking βClosed under a heat order as of July 20, 2026 β check before you drive. When open: parking is free, and the $6 Recreation.gov permit buys entry to the falls area, not a parking space.
Details, fees & parking βFree parking for up to 80 cars at the rebuilt trailhead, no permit needed β but the Forest Service closes this trail outright during heat events. Check alerts before you drive.
Details, fees & parking βTwo trailheads, two different deals: Lake Poway's big lot ($10 non-resident weekends/holidays, free weekdays, gates locked at sunset) or free roadside on Hwy 67 for a shorter, uglier, steeper climb.
Details, fees & parking βDemand-priced day use (~$10β$25), two small mesa lots that fill by mid-morning and get gated off, and free street parking outside the entrance that you have to earn by arriving early.
Details, fees & parking βSan Diego's most-hiked peak. Free lot at Golfcrest & Navajo fills by 8:30am; free street overflow β but cramp your tires on the hills and don't leave valuables in the car.
Details, fees & parking βThe east-side Potato Chip Rock trailhead. A new $5 County lot (~200 spaces) replaced the free-for-all roadside parking in March 2026 β and the shoulder is now ticketed.
Details, fees & parking βSan Diego's most popular hike. Free gravel lot with restrooms at CA-67 & Poway Rd β no pass β but it's 75β85% full by 8am weekends. Signed overflow 0.2 mi east, plus free CA-67 street parking.
Details, fees & parking β350+ free spaces at the South Entrance β full by early-to-mid morning most of the year. Springdale's paid lots ($15β$25) plus a free town shuttle are the real plan B.
Details, fees & parking βNo lot, no drive-up. Shuttle-only to The Grotto in season, and a $6 + $3/person permit lottery that buys you exactly zero parking privileges.
Details, fees & parking βThe Narrows trailhead has no lot in season β it's shuttle stop 9, a 45-minute ride from the Visitor Center. Closes above 150 CFS, and a cyanobacteria advisory is active park-wide.
Details, fees & parking βThe one big Zion hike you drive to β into a lot NPS itself warns you may have to circle for. And as of NPS's June 2026 rules, big rigs can't reach it at all.
Details, fees & parking βZion without the shuttle: separate entrance at I-15 Exit 40, park at trailheads directly, drive the 5-mile scenic road. Road reopened in 2023 after a collapse and has been open since.
Details, fees & parking βThe anti-Zion. Free shuttle you never have to ride, no reservation system, and you can drive to all four amphitheater viewpoints β but the Visitor Center lot is a 1-hour lot, not a hiker lot.
Details, fees & parking β115 spaces (7 oversize) serving the busiest trailhead in the park. NPS temporarily closes the lot when it hits capacity β and blames hikers whose cars sit there for hours. Which is you.
Details, fees & parking β49 spaces for the park's marquee sunrise view and its best hard day hike. Two demands on one small lot, and the first of them starts before dawn.
Details, fees & parking βThe quiet one. 20 spaces up a 1-mile spur that leaves Highway 63 before the entrance booth, no shuttle service, and the 8-mile Fairyland Loop starting from it. Closed to vehicles all winter.
Details, fees & parking βFifteen spaces on Highway 12, no fee booth, no shuttle, and a 0.8-mile trail to a dripping alcove and a waterfall. The purest trailhead-parking problem in the park.
Details, fees & parking βThe reservation is gone for 2026 β no ticket, no 8am scramble on Recreation.gov. What replaced it is the thing the ticket was hiding: three trailhead lots totaling 409 spaces, full for hours at a time.
Details, fees & parking β157 published spaces for the most-hiked trail in Utah. Full by 7:30am in summer, and the only Plan B turns a 3-mile hike into a 5-mile one along the shoulder of a road.
Details, fees & parking β160 spaces, the biggest lot in the park, at the very end of the road β which means if it's full you've driven 18 miles for nothing. Toilets year-round, water spring through fall.
Details, fees & parking β92 spaces, 4 oversized, and the highest turnover in Arches β the trail is a mile. Full 8am to 3pm, but a space opens every few minutes if you're willing to wait for one.
Details, fees & parking β$10 self-guided permit or a $16 ranger tour β both booked on Recreation.gov days ahead, both requiring an in-person pickup at the visitor center 13 miles away. Neither one reserves you a parking spot at the trailhead.
Details, fees & parking βThe only park in this batch that still gates entry β and it does it twice. Two permit types, two enforcement windows, two end dates, and a Bear Lake Road corridor that swallows both.
Details, fees & parking βThe park's marquee trailhead, and the one where the corridor permit bites hardest β gated thirteen hours a day, full by nine, and with no published space count to plan against.
Details, fees & parking βFour marquee hikes feed off one small lot, and the Park Service's published advice is not to try β park at Park & Ride and take the bus.
Details, fees & parking βEvery other lot in this park has a shuttle or a neighbour. This one has neither β at 11,796 feet, βfullβ means keep driving.
Details, fees & parking βThe park's most demanding trailhead has the simplest parking answer: be there at 2 a.m. like everyone else, and the reservation system you were worried about never applies.
Details, fees & parking βFive years of Recreation.gov roulette, gone. 2026 replaces the reservation with a $1 shuttle ticket, a three-hour parking clock at Logan Pass, and gate closures decided on the day.
Details, fees & parking βThe most contested lot in Glacier now comes with a countdown. Three hours, kiosk permit on the dash, and NPS stating outright that the permit doesn't get you a space.
Details, fees & parking βGlacier's most wheelchair-friendly trail sits behind one of its least forgiving lots β and the 2026 shuttle route drops the stop entirely, removing the only fallback.
Details, fees & parking βThe one page in this batch with a hard NPS number and good news attached: construction done, private vehicles back, and a rebuilt lot with 171 more spaces than before.
Details, fees & parking βThe east side's busiest short hike, with a lot NPS describes as limited and won't size β and an official workaround most visitors never hear about.
Details, fees & parking βThe reservation everyone still asks about doesn't exist this year. What replaced it is nothing β which puts the entire gate on a Valley floor that fills before breakfast.
Details, fees & parking βThree unnamed, unsized lots serving the busiest square mile in the park system β and NPS's own advice is to park once at dawn and not touch the car again.
Details, fees & parking βA 7,200-foot overlook with the best view in the park, an unsized lot, no overflow, and β right now β a tree crew stopping traffic on the only road in.
Details, fees & parking βEvery guide still describes a tiny shoulder pullout. NPS removed it in 2022, moved the trailhead to the visitor center, and banned roadside parking in the meadows outright.
Details, fees & parking βYosemite's most famous day hike has no trailhead parking at all β by design. And through October, the Mist Trail itself is weekend-only above the footbridge.
Details, fees & parking βVery busy South Rim trailhead with limited private parking. Lot D is the reliable plan: park at the Backcountry Information Center and walk or take the free Village shuttle.
Details, fees & parking βThere is no private-car parking at South Kaibab. Leave the car at Lot D or the Visitor Center and take the Orange shuttle or Hiker Express to the trailhead.
Details, fees & parking βFree NPS parking on Yerba Buena Road for Sandstone Peak and Mishe Mokwa. Small lots, winding access and no reliable shoulder overflow.
Details, fees & parking βPaved, limited lot with water and restrooms, open 8am to sunset. The weekend fallback is legal roadside space outside the road striping, not a blocked lane.
Details, fees & parking βA useful service point for Sandstone Peak, Mishe Mokwa and Happy Hollow: free NPS parking, restrooms and water, but unpaved lots on a winding road.
Details, fees & parking βUrban-edge parking for Temescal Canyon and Topanga trails. Check the local fee sign; this is not an Adventure Pass lot, and Metro and Santa Monica buses serve the gateway.
Details, fees & parking βFree NPS canyon parking near Zuma Beach. The Bonsall Drive lot is gated 8am to sunset; Kanan Trailhead fills quickly on weekends and has a marked overflow lot north on Kanan Dume Road.
Details, fees & parking βSmall dirt lot on Mulholland Highway with restrooms and water. It closes during rain, making weather the parking constraint rather than a reservation system.
Details, fees & parking βFree, serviced parking near Satwiwa and Big Sycamore Canyon. Main lot is open 8am to sunset; the gate-closed plan is front-of-gate parking or the Wendy Trailhead.
Details, fees & parking βOne of the easier local parking answers: ample free parking, restrooms and water at the former film ranch, with closures still possible during fire weather or site work.
Details, fees & parking βAcross every trailhead on this site, in every region, the single biggest predictor of a good day is arrival time. Popular Southern California lots β Heart Rock, Icehouse Canyon, Cedar Creek Falls, Potato Chip Rock β routinely fill between 7 and 9am on weekends. National-park and state-park sites add another kind of gate: a shuttle, a day-use ticket, a timed-entry reservation or a reservation-only parking slot. If a lot has a hard cap and a tow or citation risk on the shoulder, showing up at 10am doesn't mean a long walk β it means turning around. Each guide below gives the specific fill time we could verify, plus the realistic Plan B when it's already full.
The most expensive mistakes here aren't parking tickets β they're driving hours to a trailhead with the wrong pass, or none. The rules change completely by region:
Southern California national forests (San Bernardino, San Gabriel, San Jacinto ranges) mostly use the Adventure Pass β $5/day or $30/year on the dash, or an America the Beautiful pass. San Diego County is a patchwork: Cedar Creek Falls needs a $6 Recreation.gov permit (not a parking pass), while Torrey Pines is a state reserve and Potato Chip Rock's Lake Poway lot is a city park β none of them honor an Adventure Pass. National parks use entrance passes plus their own systems: Yosemite manages Valley parking and shuttles, Grand Canyon routes hikers from designated lots to trailheads, and Acadia adds a Cadillac vehicle reservation. HΔΚ»ena State Park requires advance entry and parking reservations for nonresidents.
A permit is not a parking pass, an entrance fee is not an Adventure Pass, and a reservation is not a guarantee of a space. Every guide below states exactly which one that specific lot requires.
This site covers the parking situation, not the trail's scenery: how many cars fit, when the lot fills, what goes on the dash, the tow and citation risk of getting creative, and the realistic overflow plan. Coverage spans four Southern California ranges plus national parks from Rocky Mountain and Glacier to Yosemite, Zion and the Grand Canyon, where entrance systems, shuttles and reservation rules can matter as much as the lot itself.
Mountain and desert access rules change with the seasons, so every page carries a "facts last verified" date, and the perishable ones β road closures, heat-advisory closures, permit systems β get re-checked against the official source on a recurring pass. When something changes, we fix the page rather than defend it. More on the method is on the about page.
