You board an air-conditioned coach in Miami and ride south across the Everglades and the Seven Mile Bridge to Key West. Once there, you choose between snorkeling the reef with included gear or viewing it from a glass-bottom boat, then have free time to explore the island. The coach returns you to Miami the same evening, with pickup and all transport included.
The coach is already rolling south from Miami when you cross the Seven Mile Bridge—that long, straight stretch of road where the ocean opens up on both sides and you realize you've left the mainland behind. You're heading toward Key West, and the drive itself is part of the thing: the Everglades slip past on one side, the water on the other, and the air gets warmer and slower as you go. The whole trip from South Beach takes the morning, and then you've got about six hours to do what you came for.
Once you're in Key West, you pick your water activity. The snorkel boat option takes you out to the shallow reef with basic gear included—you're in the water, looking at actual coral and fish, not watching through glass. The glass bottom boat is the alternative if you'd rather stay dry and still see what's underneath: you sit in the cabin, the reef passes below you through the transparent hull, and it's a different kind of slow. Both options leave you with free time afterward to walk around the island, grab lunch, or just sit somewhere and let the day happen. There's no rushing between stops or checking your watch against a schedule—you do the water part, then the rest is yours.
The coach is air-conditioned and has a restroom on board, which matters on a six-hour drive each way. Pickup happens from South Beach or central Miami in the morning, and the same bus brings you back the same day. You're not arranging your own transport to the Keys, not buying boat tickets separately, not figuring out timing—it's all locked in before you leave.
