Signal Peak

Overview

Also called Signal Hill on some maps, Signal Peak is the 634-foot summit of Santa Barbara Island and the island’s high point. It’s a simple idea with big payoff: climb to the top of a small, volcanic island and soak up uninterrupted ocean panoramas.

What You’ll See

From the summit you get a commanding view of the island’s rugged coastline and offshore rocks, including tiny Sutil Island to the southwest. On clear days, the outlook feels wildly expansive—nothing but cliffs, blue water, and passing seabirds.

Wildlife

Santa Barbara Island is a critical seabird stronghold. From the peak and along the approach you may spot western gulls, brown pelicans, cormorants, auklets, pigeon guillemots, black oystercatchers, and the elusive Scripps’s murrelet. In spring, keep an eye out for blooming giant coreopsis adding bright bursts of color across the slopes.

Hiking Notes

Expect a stout, exposed climb with some steep grades and potentially loose footing. There’s no shade and no facilities along the way. The route feels remote and quiet—part of the charm—so plan to be self-reliant.

Planning Essentials

• Access to Santa Barbara Island (and thus Signal Peak) is by boat only; there are no roads or parking anywhere on the island.
• There are no amenities at the summit—no restrooms, no picnic tables, no water. Bring all the water, food, and sun protection you’ll need, and pack everything out.
• Download the official park mobile app and any offline maps before leaving the mainland; connectivity is limited offshore.
• Give nesting birds plenty of space and keep noise to a minimum during breeding season.

Best Time to Visit

Clear, low-haze days deliver the best visibility and photos. Spring adds wildflowers (especially giant coreopsis) and lively seabird activity. For softer light and fewer harsh shadows, aim for early morning or late afternoon.
