The function of the rings has yet to be verified, but hypotheses such as habitation sites and ceremonial sites have been proposed by researchers. Evidence of prehistoric use of the island from 12,000 years ago to about 800 years ago has been revealed at various locations on the preserve. Due to sea level rise these deposits are surrounded by marsh, are hard to get to and are also sensitive roosting and nesting areas for various birds. Visitation is not advised. Spend your visit wildlife viewing as Manatees, sharks, osprey, eagles, dolphins, sea turtles, and a wide array of birds can be viewed during visits to the preserve.
Sport fishing is another frequent activity adjacent to the preserve.
Daws Island is also a featured attraction and primitive camp site for the Port Royal Sound Kayak trail which includes a number of natural and cultural heritage preserves and other interesting sites. Primitive camping is available with a permit. A kayak trail brochure and guide will be published in 2001. Most of the high ground on Daws Island contains sensitive archaeological deposits. Camping is restricted to the area of the preserve known as Banana Island which is depicted on USGS quadrangle maps and coastal depth charts.
