One of the wonderful activities that is very easy to do in Barbados (with or without a tour guide) is to snorkel with turtles. There are lots of tour companies who will pick you up, put you on a boat, give you snorkeling gear, put guides in the water, provide lunch, provide drinks, etc…. Or you can take your own gear, do a little research, and just swim out from the beach.
While we were in Barbados, we snorkeled with turtles using both methods. I had a great time both times. So tonight I am sharing one of my photos from snorkeling with the Barbados turtles. I think his/her name should be Crush, which was the name of the turtle in Finding Nemo.
