Rim Trail

Overview

This is Pinnacles’ crowd-pleasing sampler: a moderate 2.0–2.2-mile loop with roughly 440–500 feet of gain that packs talus caves, a tranquil reservoir, and airy rim views into about 1–1.5 hours. You’ll start near the Bear Gulch Day Use Area/Nature Center on the park’s east side, climb through the Bear Gulch talus cave (when open), pop out at Bear Gulch Reservoir, then return via the Rim Trail with wide views into Bear Gulch.

Route Snapshot

Clockwise is classic: take Moses Spring Trail through Bear Gulch Cave up to the reservoir; descend via the Rim Trail. The cave section has low ceilings, uneven footing, and occasional tight squeezes—bring a flashlight or headlamp. If the cave is closed for bat protection, you can still reach the reservoir by taking the Rim Trail as an out-and-back from Bear Gulch. Watch for signs near the reservoir; it’s easy to stride past the descent back to the lot if you’re in conversation mode.

What You’ll See

Pinnacles’ signature spires and boulders are the remnants of an ancient volcano that migrated north along the San Andreas Fault—part of why the talus caves and cliffs feel so otherworldly. On a single short loop you’ll get shadowy cave passages, the reflective water of Bear Gulch Reservoir framed by rock walls, and balcony-like rim views back over Bear Gulch.

Best Times to Hike

Spring and fall are prime. Summer heat routinely spikes and the trails are exposed—avoid 10 am–4 pm on hot days. Start early year-round to find parking and enjoy cooler temps and softer light in the canyon and along the rim. Weekdays see fewer people; weekends can fill parking early on the east side.

Know Before You Go

• Bear Gulch Cave opens and closes seasonally for bat protection—check status before you commit to the cave route and bring a flashlight/headlamp when it’s open.
• There’s no drinking water on the trail. A good rule here is at least one liter per hour, plus electrolytes in heat.
• Expect rocky footing, stairs, and narrow spots (especially in the cave). Wear sturdy, grippy footwear.
• Sun exposure is real; bring sun protection. Cell service is spotty.
• Natural hazards include poison oak, stinging nettle, and rattlesnakes—stay on trail and watch where you put hands and feet.
• Pets aren’t allowed on trails.

Extensions and Alternatives

From the reservoir, signed junctions let you extend toward Condor Gulch/High Peaks for bigger views if you’re feeling strong. Visiting from the west side instead? The Balconies Cliffs–Cave area offers a similar talus-cave experience when Bear Gulch Cave is closed.
