Valyermo sits on the north slope of the San Gabriel Mountains, and the rock climbing here draws a loyal crowd that tends not to advertise it too loudly. The area centers on Tunnel Crag and the surrounding formations, where you'll find a solid mix of routes with names like Learning to Fly, Broken Arrow, and Hip Pocket Express. The 12 active listings in the area cover a range of styles and difficulty levels, from shorter, accessible lines like Uncle Tom's Short Story and Running Boards to more committing combinations such as the Yosemite Sam's Dinner Club Combo. Routes like Ignorway and The Connection suggest there's enough variety here to keep intermediate climbers busy across multiple visits, while Paper Clip and Posing on the Edge point to some technical face climbing in the mix. The rock is primarily granitic, which means good friction and solid gear placements on most established lines. Because Valyermo sits at elevation on the desert-facing side of the range, temperatures are more moderate than the valley floor in summer and more manageable than the high country in winter, making it a genuinely year-round destination if you pick your days carefully.
Spring and fall are the most reliable seasons. Summer mornings can work well before temperatures climb, and the north-slope aspect of the San Gabriels gives Tunnel Crag and nearby formations some shade. Winter is often climbable on clear days, but check road conditions on Big Pines Highway before heading up, as snow and ice can close access.
The 12 listed routes suggest a range that accommodates newer leaders and experienced climbers alike. Routes like Uncle Tom's Short Story and Running Boards read as shorter, more approachable objectives, while the Yosemite Sam's Dinner Club Combo implies a multi-pitch or linked sequence suited to climbers comfortable managing longer days on the rock. If you're newer to outdoor leading, come with someone who knows the area.

Tunnel Crag falls within the Angeles National Forest. No climbing-specific permit is required, but the forest does require a valid Adventure Pass or interagency pass for vehicle parking at most trailheads. Check current forest closure notices before your trip, as fire-related closures can affect access with little advance warning.
A standard rack for granite sport and trad routes is appropriate here. Given the granitic rock, bring a full set of cams and nuts if you're climbing trad lines. Approach shoes are useful since some routes involve a non-trivial walk-in. Bring more water than you think you need, especially in warmer months, as there are no reliable water sources at the crag.
Approach lengths vary by route, but most lines near Tunnel Crag involve a relatively short hike from roadside parking. The exact walk-in depends on which route you're targeting, so it's worth checking a current guidebook or recent trip reports for Tunnel Crag specifically before assuming you can walk up in five minutes.
