One of our favorite things that we did on our trip to Kiawah was walking one day and riding bikes another day to the mouth of the Kiawah River at Beachwalker Beach. If you go during low tide, you will see dolphins strand feeding. It is an amazing sight to see. Definitely go, but be respectful of the dolphins and stay back from the river bank. When we were there, an ignorant group of people walked to the rivers edge to get a closer look and the dolphins swam away.
