What makes Sand Key worth the trip
Three things you only get here.
Most Key West sandbars are sandy flats in protected backcountry water. Sand Key is different — it’s a working reef on the southern edge of the Florida Keys reef tract.
The lighthouse
Sand Key Lighthouse went into service in 1853 and survived the 1865 hurricane that destroyed the original keeper’s quarters. Still standing on its iron-pile foundation. The photo from the bow of your boat is the iconic Florida Keys shot.
The reef
Shallow coral (8–15 feet typical) within easy snorkel reach of the lighthouse. Parrotfish, sergeant majors, queen angelfish, occasional nurse sharks. Visibility is usually 30+ feet on clean-water days.
The emerging sandbar
At low tide a section of the sandbar comes out of the water and you can step onto it. At high tide it’s fully submerged but still shallow enough to stand in. Tide timing makes the trip — we plan around it.
A half-day from Key West
What you actually do at Sand Key.
Sand Key trips are a half-day for most groups — about 30 to 40 minutes from our Perry Hotel & Marina dock on Stock Island out to the lighthouse, then two and a half hours on site, then the run home. Long enough to swim the reef, lounge on the sandbar, and sit at anchor in the lee of the lighthouse for lunch. Short enough that it’s an easy add to a Key West day.
Snorkel the reef.
The coral around the lighthouse base is among the most accessible snorkel reefs in the Lower Keys. You don’t need to be a strong swimmer — the water is shallow and the reef is right under the boat. We carry full snorkel kits aboard in adult and kid sizes. If you’ve never snorkeled before, this is a soft place to start.
Lounge on the sandbar.
At low tide a strip of dry sand emerges next to the lighthouse and you can walk on it like a beach. Bring a cooler, a towel, sunscreen. We anchor the boat alongside and you can step off the swim platform into knee-deep water. Some groups spend the whole trip on the bar and skip the snorkel; some do both.
Read the lighthouse.
The Sand Key Lighthouse is a National Register of Historic Places landmark. Built 1853 from the same iron-pile design that survived the destruction of the original Sand Key Lighthouse in the 1846 hurricane. It’s not open to climbers, but you can approach to within a few feet from the water. Bring a real camera if you have one — the contrast of black iron, white tower, blue water is striking.
Pick the right day.
South wind days deliver glass water and great visibility at Sand Key. North or northeast wind days push chop down from Key West and reduce visibility on the reef. We watch the forecast and will proactively reach out if your scheduled trip is going to be a low-visibility day — rescheduling is always an option for our private-charter guests.
How Six Fins gets you to Sand Key
Two ways to spend a day at Sand Key.
Most Sand Key visits happen on a private boat charter from our dock at the Perry. If you want a snorkel-only focused day, our snorkeling charter is built around the reef. If you want flexibility — lighthouse, sandbar, snorkel, lunch — book the private charter and tell the captain Sand Key is the destination.
Private Boat Charter
Your group only, your day, your captain. Tell us Sand Key is the destination and we build the itinerary around tide timing and weather. Up to 6 guests standard, 8 by arrangement. $1,195 for the 4-hour Escape; Custom Combo $1,395 (6 hours) / $1,795 (8 hours).

Sand Key questions, answered.
Where is Sand Key?
Sand Key is about 7 miles south-southwest of Key West, on the reef side of the island near the western edge of the Florida Keys reef tract.
It is marked by the historic 1853 Sand Key Lighthouse and is reachable only by boat.
What makes Sand Key different from other sandbars?
Sand Key combines three things in one destination: the lighthouse, shallow reef snorkeling, and a sandbar that can emerge at low tide.
Most backcountry sandbars are about shallow sand and calm water. Sand Key is more exposed and reef-focused, which makes it one of the best choices when guests want both an iconic Key West photo and a real snorkel stop.
Can we walk on the Sand Key sandbar?
At low tide, yes, a portion of the sandbar may emerge and be walkable. At high tide, it may be fully submerged but still shallow enough for wading and floating.
Tide timing matters. Tell Six Fins whether dry sand or snorkeling is more important so the captain can recommend the best departure window.
Is Sand Key good for snorkeling?
Yes. The reef around the lighthouse is shallow, commonly described around 8–15 feet, and can be excellent for beginner-friendly snorkeling when visibility is good.
Guests may see parrotfish, sergeant majors, queen angelfish, nurse sharks, and other reef life, but wildlife and visibility are never guaranteed.
Can we climb the Sand Key Lighthouse?
No. The lighthouse is not open for climbing or public entry.
The view from the water is the attraction. The captain can position the boat for photos when conditions and safety allow, but guests should treat the structure as historic and off-limits.
How long does it take to get there?
The run is usually about 30–40 minutes from Perry Hotel & Marina depending on wind, sea state, and route.
A typical Sand Key charter leaves enough time to snorkel the reef, wade or float on the sandbar, take lighthouse photos, and relax at anchor before returning.
Is Sand Key weather-sensitive?
Yes. Sand Key is on the open-ocean / reef side of Key West. Wind direction and swell can affect comfort and visibility.
North or northeast wind can reduce visibility and make the reef less enjoyable. If Six Fins or the captain determines Sand Key is not the right call, the team may recommend another sandbar, another day, or a private snorkel route that fits conditions better.
What should we bring?
Bring reef-safe sunscreen, swimwear, towels, sunglasses, a hat, snacks, drinks, and a camera or phone protection.
Six Fins provides the private boat, captain, safety gear, cooler setup, and snorkel gear where included. Reef-safe sunscreen matters here because Sand Key is a reef destination, not just a beach stop.
