No pass, no fee โ€” but plan around the crowd

Iron Mountain is regularly called San Diego's most popular hike, and the parking is refreshingly simple: the main gravel/dirt lot at 14847 CA-67 is free, open 24 hours, and needs no pass. No Adventure Pass applies โ€” this is a City of Poway trailhead, not a national forest fee site. The real constraint is timing. On weekends the lot hits roughly 75โ€“85% capacity by 8am, so the difference between a five-second park and circling for a spot is showing up before 7:30. Weekday mornings are wide open by comparison.

When the main lot fills: overflow and CA-67 street parking

The trailhead has a signed overflow lot about 0.2 mile east of the main parking, and hikers are specifically asked to use it once the main lot is full rather than jam the entrance. Beyond that, free street parking along CA-67 is common โ€” pull fully off the travel lane, don't block driveways or gates, and honor any posted no-parking stretches. It adds a short walk but keeps the trailhead approach clear.

What to expect on the trail

The Iron Mountain Trail is a ~6-mile round-trip, moderate climb to a summit with picnic tables and big views. It's dog-friendly (leashed) and open to mountain bikes (10 mph limit), so mornings mix hikers, runners, and riders. The single most important prep note is water and sun: the route is almost entirely shadeless, so carry more water than you think you need and start early in summer. Restrooms are at the trailhead, not on the trail.
