Trail map and regulations
While hiking, remain on established trails or on the shoreline where there is no vegetation.
Falling rocks are a hazard near the cliffs. When possible, keep a safe distance, avoid walking beneath overhanging rock and do not stop next to the cliffs.
At low tide, water and seaweed on the rocks create slippery conditions. Please proceed with caution.
