South Bay Access provides entry to the South Bay Paddling Trail, an approximately 8-mile loop through a pristine, shallow subtropical bay with extensive seagrass beds and black mangrove stands.

Primary access is via Isla Blanca Park on Padre Boulevard south of the Queen Isabella Causeway on South Padre Island (956-761-5493), though the remote location requires paddlers to bring adequate water and sunscreen.

Due to the bay's numerous oysters and shallow, mucky bottom, proper footwear is essential and the area is unsuitable for wading.
