If you like camping and water sports, you will love SISP. The park is sorrounded by water, you have the Indian River Lagoon, The Sebastian Inlet and the Atlantic Ocean. The campgrounds is located on the Sebastian Inlet. The sites on the 1st camp loop face the inlet. The views are breathtaking. You can watch the stingrays and dolphins jumping out of the water. You can watch the sunrise over the Atlantic and watch is set over the Inlet. There is an awesome cove area that is perfect for families with small children. There are two boat ramps located within the park, one for motorized vessels and one for non motorized vessels. They also have a marina about a mile down the road where they have boat, kayak and SUPB rentals. SiSP is home to the world famous fishing pier. There are two fishing piers that extend out into the Atlantic ocean. Great for catching shark, Snook and Redfish. You can snorkel and scuba dive in the Cove (great for small children), Inlet or Atlantic, you have to have your own gear. There is a reef just a few hundred yards off the beach. There is an abundance of sea life including , dolphins, manatees and sea turtles. Dont forget to bring your surfboard. The museam offers sea turtle walks during nesting season. If you have a boat you can go out to the sandbar and anchor out for a day fun on the water. There is a great restaurant that has dining views of the Atlantic ocean. I had lunch up on the deck one day and watched the Tarpon run. The restaurants serves breakfast and lunch. I recomend the Mahi sandwich with a cold beer. They also serve alcohol and wine. They show movies on the water. Enjoy a movie while you float in the cove on you tube.
