Trail guide
Follow the signed route from the Scorpion area toward Cavern Point, continue west on North Bluff Trail, then return via Potato Harbor Road and the Scorpion Valley access. The stored line is the complete loop and closes at the mapped Scorpion access point; the listed distance is the visitor loop total of 3.8 miles. Allow about 2 hours, depending on pace and stops. The separate Potato Harbor out-and-back continues farther along North Bluff and is a different visitor experience.
Expect open island grassland, coastal bluffs, seasonal flowers, and wide views of Scorpion Anchorage and the rugged north shore. The Potato Harbor overlook is the destination highlight, and island foxes and seabirds may be seen around the route.
There is no visitor parking on Santa Cruz Island; arrive by boat at Scorpion Anchorage and begin near the Scorpion area. Carry water, food, and sun protection because the loop is exposed and has no services along the route. Cliff edges are unfenced and unstable in places, so stay well back from the rim. The harbor has no beach access from the overlook. Pets are not allowed on park trails; service-animal rules apply.
