Awesome Waterfront Sites
You have 2 choices when you camp at Sebastian Inlet, the state park and Longpoint, which is a Brevard county park. Having been to both I choose LP, because of the several waterfront sites that you can camp at, launch your kayak from, fish and some even swim. It is also driving/biking distance to the SP beaches (don't miss the cove.) Whereas if your camp at the SP you would have to walk your bike over a very active bridge to the beach.
LP bathrooms were clean and in good order.
Negatives: (1) Everybody parked their RV anyway they wanted on their site to get full view of the water. (2) Uneven ground and a drop off from pavement. (3) Children need to be watched when biking. It is very busy with boats trailers & RVs.
Finally, make sure you are prepared for mosquitoes and other pesky biting flies. An outdoor room is recommended.
