Turtle Beach offers a public beach access that is south of the Point-of-Rocks neighborhood. On this southern part of the island the beach is markedly different from the wide, flat, white-quartz beaches of northern and central Siesta Key. Turtle beach has a steeper slope than other beaches on Siesta Key and the sand is much softer and harder to walk on. You cannot ride your bike on Turtle beach. The sand is too soft. Mixed in with the quartz sand is quite a bit of crushed shell and dark fossilized material.
Turtle Beach is definitely a quieter beach, but Crescent Beach and Siesta Public beach are much better suited for younger children, for older adults that may have trouble walking in very soft sand, and for jogging or bike riding. The water at Turtle Beach gets deeper more quickly than the water on the rest of the island. Some adults may prefer this because you don't have to go so far from the beach to find chest deep water.
Turtle Beach is located at the southern end of Siesta Key in Sarasota. Midnight Pass Road will take you to Turtle Beach. Midnight Pass Road continues past Turtle Beach for a short distance before it dead-ends. Turtle Beach is reached by turning off of Midnight Pass Road onto a spur road called Blind Pass Road, which parallels the beach before disappearing into a private condominium called Fisherman's Cove.
Turtle Beach is unique because this part of Siesta Key is very narrow. Not only is it narrow, but there is a lagoon in the middle of the island that separates the narrow beach strip from the bay side of the island. So, there is not a lot of land here to be developed.
The Turtle Beach area has a lot of condominiums of two to four levels. The condominium furthest south on Siesta Key is called Fisherman's Cove. It sits right on the beach. The other condominiums, along with several restaurants and a Marina, are on the bay side of the island. The condominiums are a good choice for a vacation rental in the Turtle Beach area of Siesta Key and there are some private homes for rent between Turtle Beach and Midnight Pass to the south.

The main attraction on Turtle Beach is quiet. There is almost no commercial activity in this area other than a few (very good) restaurants and a small marina. The public beach access is responsible for most of the traffic in the area.
There is also a campground right next to the public beach. It is quite narrow but does accommodate some rather large motor homes. The campground is called--what else: Turtle Beach Campground. Tents are allowed but 95% of the "campsites" are filled by motor homes or camping trailers.
Casey Key is immediately to the south of Siesta Key and is a separate community. The two islands, Siesta Key and Casey Key used to be separated by Midnight Pass. This pass is now filled in with sand, so the two islands are now joined. However, there is no road going across Old Midnight Pass, therefore you cannot drive from one island to the other, you must take US 41 through Sarasota.
