Old Pinnacles Trail

Overview

Old Pinnacles to Balconies Cave is the east-side crowd-pleaser at Pinnacles: a mostly gentle walk along Chalone Creek that dives into a talus cave, then pops you onto the Balconies Cliffs for wide-open views. It’s about 5.3 miles total from Old Pinnacles Trailhead if you make the cave-and-cliffs loop, and most hikers spend 3–5 hours depending on water levels, crowds, and photo stops. Elevation gain is modest, but the cave adds a dash of scrambling and fun.

Route and options

From Old Pinnacles Trailhead, follow the Old Pinnacles Trail along Chalone Creek toward Balconies Cave. Many hikers do a loop: through the cave one way and back via the Balconies Cliffs Trail for big vistas of Machete Ridge and the Balconies. If the main lot is full, you can start at the Visitor Center/Campground and use the Bench Trail to connect—this adds mileage. Note there’s no road through the park between the east and west entrances, so plan your approach accordingly.

Caves, crossings, and conditions

Balconies is a talus cave—boulder ceilings bridging a narrow gorge—so bring a reliable flashlight or headlamp. Expect up to six seasonal creek crossings along the approach. After storms or in spring runoff, water inside the cave can be knee-deep; be ready for wet feet and slower going. Cave segments can close for safety or wildlife; check current cave status at the park before you commit. If you’re claustrophobic, consider skipping the cave and using the Balconies Cliffs section as a scenic out-and-back instead.

What you’re seeing

These crags are remnants of a volcanic field that erupted roughly 23 million years ago and rode northwest about 195 miles on the Pacific Plate along the San Andreas Fault. The caves formed where huge blocks tumbled into narrow canyons and wedged overhead. Keep an eye on the sky—this is prime California condor territory over the cliffs—and stay alert for rattlesnakes warming on sunny edges.

Best times to hike

Spring and cooler fall days are the sweet spot for temperature and wildflowers. Summer can be brutally hot and exposed; start early for shade, easier parking, and fewer crowds. Weekdays are calmer than weekends and holidays. Photography is kindest in the morning when the cliffs glow and you’re not squinting your way through heat haze.

Know before you go

Carry plenty of water, sun protection, and sturdy, grippy footwear. Cell service is limited, and intersections come fast—study the map and double-check signs. Pets and bicycles aren’t allowed on park trails. A seasonal shuttle may operate on the east side; parking is limited, so arrive early or be ready to walk in from the Visitor Center.
