Glacier National Park Entry & Going-to-the-Sun Road

The reservation is gone, and that is not the good news it sounds like

From 2021 through 2025, getting into Glacier meant winning a Recreation.gov slot months out or at 7 p.m. the night before. For 2026 the park dropped it entirely. No corridor requires a vehicle reservation.

Before celebrating, understand what the reservation was doing. It rationed cars against a road that has a fixed number of parking spaces at the top. Removing the ration doesn't create spaces — it changes who gets them from “whoever was fastest on a website in February” to “whoever is earliest on the road in July.” NPS is candid that its fallback is reactive closure: rangers close a corridor to incoming vehicles when it fills, with no advance notice and no way to plan around it.

So the failure mode has changed shape. Under the old system you knew in March whether you were getting in. Under this one you find out at the entrance station, having already driven there.

What actually gates you now

Three separate mechanisms, and only the first is a ticket you can buy in advance.

The Logan Pass shuttle costs $1 per person aged 2 and up and requires a Recreation.gov reservation — there is no walk-up option. Tickets released 60 days ahead starting May 2, with a night-before tranche at 7 p.m. MDT from June 30. It runs July 1 to September 7 only.

The 3-hour parking limit at Logan Pass applies 24 hours a day across the same dates. You park, walk to a kiosk, take a free timestamped permit, and put it on your dashboard. Three hours is enough for Hidden Lake Overlook and not enough for the Highline to the Loop.

Reactive corridor closures are the one you can't plan for. When a lot or an area fills, incoming traffic gets turned back until it drains.

A thing worth saying plainly, because the old system trained people to think otherwise: none of these guarantees you a parking space. NPS says so about its own permit — “a parking space at Logan Pass is not guaranteed.” The permit starts your clock; it does not reserve your spot.

The free shuttle people remember doesn't exist any more

Glacier ran a genuinely free, walk-up, hop-on GTSR shuttle for years, with stops down the length of the road. If that's your mental model, update it.

The 2026 Logan Pass Shuttle is ticketed, costs $1, must be booked in advance, and has a short stop list: Apgar Visitor Center, Lake McDonald Lodge, St. Mary Visitor Center, Rising Sun Picnic Area, The Loop, and Logan Pass. That's it.

What that omits matters more than what it includes. Avalanche Creek and Trail of the Cedars are not stops. Neither is the St. Mary Falls trailhead. Neither is Many Glacier. Three of the park's busiest short-hike lots now have no shuttle fallback at all — if they're full, your options are to drive on or come back. This is a real reduction in service against the old system, and it isn't advertised as one.

The 21-foot rule strands somebody every week

Independent of every reservation question, Going-to-the-Sun Road has hard vehicle size limits, and they are enforced by the geometry of the road rather than by a ranger's discretion.

“Vehicles and vehicle combinations longer than 21 feet (including bumpers) or wider than 8 feet (including mirrors), are prohibited between Avalanche Creek and Rising Sun.” Including bumpers and including mirrors are doing real work in that sentence — a 22-foot van with mirrors folded is still a 22-foot van.

Separately, vehicles over 10 feet tall may have trouble heading west from Logan Pass to The Loop because of rock overhangs. That's phrased as a difficulty rather than a prohibition, which in practice means it's your paint.

If you're over the limit, the middle of the road is closed to you and the shuttle becomes the only way to see Logan Pass. Oversized vehicles can still reach Packers Roost from the west and Siyeh Bend from the east — that's the extent of the workaround.
