Down at the far end of
Siesta Key, Turtle Beach is one of the lesser-known and visited beaches near Sarasota. Ideal for those looking for a different kind of beach, Turtle Beach is a very laid-back place with few crowds. The beach is different from the others just a short distance north in the fact that it has black and white, "salt and pepper," sand.
Turtle Beach has a unique formation: a bench of sand. This means that you actually sit about four feet above the water, allowing you to see down and easily spot marine life, including colorful fish and, occasionally, small stingrays. To access the water, you just step down through the soft sand to the hard-packed sand at the water's edge.
Although the beach is always changing, Turtle Beach generally has small points that extend out into the water, these in turn create small coves. The water extending out from these points is especially shallow, and you can easily walk out quite a distance.
If you are a beach walker, consider heading south to Palmer Beach Park. Walk past the condos for about a mile, and then you'll have a wonderful long stretch of undeveloped beach all to yourself. Palmer Beach Park is only accessible along the beach or by boat, so the shelling down here can be quite good. Alternatively, bring your own kayak or rent from the vendors near the boat launch in behind the beach and paddle down through the
Jim Neville Marine Preserve to the park.
