This facility, approximately 10-acres, is located on SR/CR 867, consists of the road sides of two spoil islands built and used to link the mainland to Sanibel Island. The causeway bisects San Carlos Bay a short distance from the mouth of the Caloosahatchee River, that allows bay and gulf side access.

As you are traveling from the mainland towards Sanibel Island you will pass through a D.O.T. Toll booth (toll is $6 , no fee required for park use) then crossover a "sky" bridge and arrive at the first island, referred to as "Island A". If you continue on, you will crossover another "flat" bridge and arrive at the second island referred to as "Island B".

Both islands have been a very popular destination since built and can accessed from the water as well. Some of the activities enjoyed are fishing, wading/swimming (beware of submerged structures), picnicking, canoeing/kayaking, (no launching or retrieval of vessels, this would include both aerial and water type crafts), wind surfing, kite boarding, shelling, sun bathing or just plain relaxing in the shade.

Island "A" has parking only. Island "B" offers restrooms, drinking fountains (located on each side of the road) and a few picnic tables on the gulf side. Grilling is permitted, so feel free to bring your own. No ground fires permitted. No alcoholic beverages allowed. Leashed pets welcomed but, please remember to clean up after your pet.

    Great beaches and space to play!

    We enjoy the free parking here, plus the wonderful water. This also is quicker to get to, and leave from, compared to the other wonderful Sanibel/Captiva beaches.

    Pets Best Kept Secret

    I was visiting Sanibel Island and the local area for an upcoming job interview and happened upon Casueway Park. I was traveling with my Miniature Pincher and wasn't planning on stopping just sightseeing. We noticed other pets along the causeway and stopped to take a look. It is a wonderful relaxing area with picnic tables, restrooms as well as grills. The park is very pet friendly and the water is clear and shallow to allow wadding for pets as well as kayaking and any other water sports and activities. Well, I got the job and since being here I make it nearly an every weekend stop just for my pet to take a dip and relax.
