Incorporated in 1973, it lies just across Laguna Madre, the bay separating island from mainland. Not surprisingly, the East side of the island is referred to as the "gulf side" by locals, and the West side, the "bay side".
Texas State Route 100 connects South Padre Island to the city of Port Isabel on the mainland, and continues on to meet US Route 77/83 between Harlingen and Brownsville. Texas State Route 48 links Port Isabel with Brownsville. If you will be landing at McAllen Miller International Airport, US Route 83 directly connects the airport to Texas State Route 100, passing through Harlingen en route.
Catch the $2 Rio Transit bus from downtown Brownsville to its last stop in Port Isabel, and catch the free Wave from there. The Wave runs every half hour and takes you all over South Padre as far as the Visitors Center on the north end.
There are no ferry boat services, but if you have your own boat, just point yourself to the place on the Gulf of Mexico where Texas meets Mexico and you're at South Padre Island! There's several marinas both on South Padre and at Port Isabel.
Sea Ranch Marina - offers transient slips on a space available basis 
Anchor Marina Park - deep water slips on the Port Isabel side of the causeway 
South Padre Island has only one main road: Padre Boulevard, which is part of Texas State Route 100. There are two parallel side streets, Gulf and Laguna. There are several taxi-cab companies, with fares starting at around $5.
The South Padre Island Visitors Center provides detailed information about accommodations, activities and events related to boating, sailing, fishing, and seashore recreation.

South Padre is known for its water sports and is a famous international destination for kiteboarding or kitesurfing. Other popular watersports include jet skiing; bay, surf, and deep-sea fishing; parasailing, sailing, dolphin cruise, and windsurfing.
