Captive Island offers more opportunities than Sanibel if you are looking to tie up for the day. During the off season Tween Waters Inn allows you to dock and use their facilities and beaches as if you were a paying guest. Great pool, bar and food service right to your lounge chair. The best part is the price, $35.00 for the day and get a $20 credit at the bar. There other bars and restaurants in the area that offer transient docking too.

Redfish Pass is located between North Captiva Island and Captiva Island. The beaches are surrounded by fine white sand and the emerald green water of the Gulf. From Castaway Cottage in St. James City, it's a 45 min boat ride north west or about 10 miles. If the Gulf is calm you can anchor on the north Captive side. This beach is one of the nicest around,  and is only accessible by boat. Boat rentals are available at http://www.monroecanalmarina.com/
