Fort De Soto County Park occupies the southernmost tip of the Pinellas County barrier island chain, about 30 minutes from downtown St. Petersburg. Just offshore from the park's western edge is Shell Key Preserve — a state-protected area of uninhabited barrier islands, tidal flats, and shallow sandbar areas that's accessible only by kayak or small boat.
The kayak tours that run into Shell Key Preserve from the Tierra Verde launch point are among the best guided kayak experiences in the Tampa Bay area. The water is shallow enough to see the bottom throughout most of the paddle, the preserve is protected from powerboat traffic, and the wildlife — dolphins, manatees, ospreys, herons, and shorebirds — is consistently present.
Shell Key Preserve: What You're Paddling To
Shell Key Preserve covers about 1,800 acres of islands, tidal flats, and open water between the Fort De Soto peninsula and the Gulf of Mexico. The main island — Shell Key itself — is a low-lying barrier island with a Gulf beach on the west side and a shelling/wading area on the interior flats. The island is a designated nesting area for least terns, black skimmers, and American oystercatchers, which means sections of the beach are periodically closed during nesting season (roughly April through August).
The sandbar areas inside the preserve are the draw for most visitors. At low tide, large sections of the flats are ankle-deep or shallower, which is excellent for wading, shelling, and spotting rays, crabs, and small fish in the sand.
Get Up and Go Kayaking — Tampa Bay
Get Up and Go Kayaking is the primary guided kayak tour operator for the Shell Key Preserve area. They launch from Tierra Verde, which is the small island community between Fort De Soto and the mainland just south of St. Pete Beach. Their tours use clear-bottom kayaks — transparent-hulled kayaks that let you see the seafloor as you paddle, which is particularly impressive in the shallow, clear water of the preserve.

Guided eco kayak tour to Shell Key Preserve from Tierra Verde. Standard kayaks (not clear-bottom). Covers the preserve's tidal channels, sandbar, and shelling beaches. The most affordable guided kayak option in the area. Good for kayakers who are comfortable with standard equipment and want the lowest-cost guided option.
Check Availability →How the Paddle Works
The launch from Tierra Verde takes you through a protected bay area before reaching the open water between the mainland and the barrier islands. The paddle to Shell Key's main sandbar area is approximately 1-1.5 miles depending on conditions and the specific route the guide takes. The total trip covers about 3-4 miles of paddling in two hours, which is manageable for most people who have never kayaked before.
The clear-bottom kayak tours are the better experience for first-timers — watching the sandy bottom pass beneath you as you approach the sandbar is one of the more visually interesting parts of the trip. The preserve's water is typically clear enough in calm conditions to see the bottom in 4-6 feet of water, which is most of the paddle route.
What You'll See in the Preserve
Wildlife sightings in Shell Key Preserve are reliable year-round:
- Dolphins: Common in the channels and around the sandbar, especially in the morning. They're often working the channel between the mainland and the preserve.
- Manatees: Present year-round but more common in warmer months. You'll sometimes see them surfacing in the calm bay areas near the launch.
- Shorebirds: The preserve is a significant shorebird nesting area. Brown pelicans, great blue herons, tricolored herons, and roseate spoonbills are common.
- Marine life: Stingrays, horseshoe crabs, and small fish are visible through the clear-bottom kayaks on the shallower sections of the paddle.
Nesting season restrictions: From roughly April through August, parts of Shell Key's beach are closed for bird nesting. Your guide will know which areas are restricted on any given day. The sandbar wading area is typically still accessible even during nesting closures.
Getting to Tierra Verde
Tierra Verde is on the Pinellas Bayway (State Road 682), between St. Pete Beach and the Fort De Soto Park entrance. From downtown St. Pete, take I-275 south to the Pinellas Bayway exit and follow signs toward Fort De Soto. The kayak launch points are in the small marina area at the north end of Tierra Verde. Both operators will send you launch location details with your booking confirmation. Parking is available in the marina area — free on weekdays, metered or limited on weekends.
