Sand Island is a 7.5 mile trail located near Dauphin Island, AL and is rated as moderate. The trail is primarily used for sea kayaking and is accessible year-round.
Kayaking along the main island is great on the bay side. Sand Island is also a wonderful place to experience the Gulf, especially if you make it to the end. People who enjoy birding will love Dauphin Island because it is a bird sanctuary.
I walked and biked on practically all of Dauphin Island. Then drove to golf course and viewed Sand Island from a distance. From east end to west end of the island, it was totally paved with walking trails! Easy walking and biking. When I biked to the west beach, I had a bit of a time biking back against the wind! Lovely weather. Laid back island fun!
