Programs and activities are weather and tide dependent. Make sure you check the tides before you head out to explore. Conditions vary from day to day. Both of the photos below were taken mid-afternoon on different days.

  • Tidepooling in the afternoon in the photo on the right may lead to some excellent discoveries and seeing cool creatures.
  • Tidepooling on the afternoon in the photo on the left will most likely lead to a wet (and possible dangerous) trip with very little to see.

Check tides in the newspaper or click here for tides and weather conditions. Remember, the lower the tide, the better your experience

 Here is a sample of the same beach at low tide and high tide.
