Know When to Go

This land bridge is exposed at low tide. The opportunity to tide pool 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 Bar Island.

Be cautious and aware of the tides, as the bar is otherwise covered by the ocean. If you walk over to the island and lose track of time, it is 9 hours until the bar emerges again to safely walk across.

Safety and Etiquette

  • Before exploring, wash off sunscreen, hand sanitizer, and bug spray.
  • Do not wade into the tidepools.
  • We are guests in these animals’ homes. Use a light step!
  • Leave the park as you found it. Never use force to remove anything.

Slow is the Way to Go

Step carefully and slowly. Seaweed is slippery, and rocks can be wet, loose, and/or sharp.

Protect Your Feet

Wear closed-toed sturdy outdoor shoes.

Eyes on the Sea

Keep a safe distance from the sea, and watch those waves.

Kids Stay Close

Small children should stay within arm’s reach of adults.

"Sea" a Whole New World

Get low, look closely and carefully, and have patience!
