Captains Island Daniel Island Park For Sale. Located at the end of Daniel Island Park, Captains Island has its own bridge and the 100 acre island will have approximately 99 lots. Most of the lots will be around the perimeter of the island with either deep water docks, creek docks, or great marsh views. The interior lots all back to a pond, wetlands, or nature, therefore no one will back directly to another home. The island’s amenities will include a vast nature trail winding through the island and a community day dock connected to a pavilion that can only be used by those who live in this section. The pricing in the first release is going to be very attractive with home sites priced from the $300’s to $1.2 million.
