What can I do or see on Decatur Island? 

  • The public beach at the southern tip of Decatur is a lovely boating destination. 
  • The public shore connects a rocky bluff to the main part of the Island with a two-sided pebble beach. The protected bay this creates is a great place to spend a day or night in your boat. 
  • The pebble beach is a lovely and manageable kayak trip from Mud Bay on the south end of Lopez Island. Intrepid kayakers can use the public beach as a picnic lunch spot on their way to camp on James Island. 
  • James Island State Park is a beautiful place to visit and just off the eastern shore of Decatur.
