  • Stay on the established trail. Keep an eye out for poison oak.
  • Observe warning signs and railings—these exist for your safety.
  • Dress in layers and be prepared for varying weather conditions. Sunny days along the coast can turn windy, foggy, and cold very fast.


There is trailhead parking at the end of Sneath Lane. Note: the park is working on plans to add an accessible parking space.


A vault toilet is located atop Sweeney Ridge, but there is no running water.

Trail Etiquette

Leashed dogs are permitted on Sneath Lane Trail. Please remain on the established trail. Off-trail travel harms plants and causes erosion. Keep your food within arm's reach at all timesand do not feed the wildlife. Carry out all trash and food waste (fruit peels, shells, etc.).
