What to Expect

This trail wastes no time getting interesting. From the Bear Gulch Day Use Area, you climb steadily through oak woodland and chaparral before the real attraction reveals itself: a labyrinth of talus caves formed by massive boulders wedged together overhead. You'll squeeze through narrow passages, duck under low ceilings, and navigate stretches of near-total darkness where a headlamp isn't optional — it's essential. The moderate elevation gain feels steeper than it sounds because much of the terrain is rocky and uneven, with metal staircases and handrails bolted into the rock where the cave system demands it. The caves themselves are the payoff — cool, echoing chambers that feel genuinely wild, not like a tourist attraction with guardrails and gift shops. Families with adventurous kids, geology nerds, and anyone who's ever wanted to spelunk without the full commitment will love this one.

Safety Advisory

Cave passages involve tight squeezes, low ceilings, and slippery rock surfaces. Anyone with claustrophobia or limited mobility should reconsider — there are sections where you're crouching through gaps barely wider than your shoulders.

Flash flooding can make cave sections dangerous after rain. If storms are forecast, skip the caves entirely — water funnels through the talus system fast and there's nowhere to go.

Pro Tips

Trail Tip

Check the NPS website or call the visitor center before you go — the upper cave section closes from mid-May through mid-July for Townsend's big-eared bat maternity season, and closures can shift. The lower caves may remain open, but the full loop requires both sections.

Trail Tip

Bring a real headlamp or flashlight, not your phone. Several cave sections are pitch black for 50-100 feet, the footing is uneven, and you need both hands free to steady yourself on wet rock and metal ladders.

Trail Tip

Start early on weekends — the parking lot at Bear Gulch fills by mid-morning, especially in spring. If it's full, you can park at the Chaparral lot and take the Moses Spring Trail connector, which adds about a mile but avoids the crowds at the trailhead.
