Thing to Do
Tidepooling at Wonderland

Take the flat, easy Wonderland Trail through a coastal forest with minimal roots and rocks before reaching the coastline. There is a rocky tidepooling area at the end of the trail. Keep an eye out for bountiful barnacles and a variety of marine snails alongside the long spaghetti-like rockweed algae. Camouflaged crabs and soft green sponges can be spotted as well through patient observation.
- Distance: 1.4 miles round trip
- Terrain: area along coastline is uneven and slippery, especially on the black rocks and seaweed.

Know When to Go
This rocky tidepooling area is exposed at low tide. The opportunity to tidepool occurs between the window of time 1.5 hours before to 1.5 hours after low tide. It is best to start tidepooling before low tide and to leave as the tide is rising.
Before you head out to the intertidal zone on your own, check the tide chart for Wonderland.
