What are Sarasota's barrier islands?

They're the Gulf-front keys just west of the city of Sarasota — principally Longboat Key, Siesta Key, Lido Key (with St. Armands) and Casey Key. Each is its own beach community, connected to the mainland by bridges and causeways, with a mix of condos, canal homes and Gulf-front estates.

Where are these islands located?

Longboat Key runs along the Sarasota–Manatee line; Lido Key and St. Armands are across the Ringling Bridge from downtown Sarasota; Siesta Key is a short causeway south of downtown; and Casey Key stretches south toward Nokomis and Venice. All are within a few minutes of Sarasota's dining, culture and airport.

Can I get a Gulf-front home?

Yes — all four islands have Gulf-front options, from beachfront condos on Lido and Siesta to Gulf-to-bay estates on Longboat and Casey Key. The live counts and pricing on this page show exactly what's on the market on each island right now; Gulf-front inventory is limited, so it moves quickly.

How often is the listing data updated?

Inventory, pricing, days-on-market and open-house counts on this page are pulled from the local MLS and refresh throughout the day. The "Listing data updated from the MLS" note under the comparison table shows the most recent successful refresh.

How do I compare the islands?

Use the compare checkboxes on each island card to add up to four islands to the comparison tray, then select "Compare Now" to jump to the side-by-side table of inventory, pricing, open houses and amenities. You can also ask Ivy to build a personalized shortlist based on the island lifestyle you want.

Can I schedule a private tour?

Absolutely. Open any island with "Explore Community" to see current homes, or ask Ivy to connect you with a local agent. We can arrange private tours of specific homes or a driving tour of several islands in a single visit.
