Miami to Key West Day Trip — Snorkeling, Dolphin Watching & Glass-Bottom Boat
Select participants and date
The bus pulls away from Miami before first light, air-conditioning humming as the skyline shrinks and the highway becomes a ribbon of sea and concrete. Across the Overseas Highway the water changes color—brighter, cleaner blues—until Key West materializes like a bright coin pinned to the ocean. You get a few hours here, long enough to let salt and sun reset your internal clock: to stand at the rail and watch for bow-riding dolphins, slip a mask over your face to meet a shallow reef, or lean against the glass bottom and watch coral gardens drift beneath you.

Adventure Tips
Expect a long day
This tour is roughly 15 hours door-to-door—bring layers, snacks, and plan for an early pickup and late return.
Bring reef-safe sunscreen
Coral reefs are sensitive; choose reef-safe sunscreen and reapply after swimming to protect marine life.
Manage seasickness proactively
If you get motion sick, take medication before boarding and sit mid-boat where motion is milder.
Carry small cash
Many island vendors and street food stalls prefer cash for quick purchases during your free time.
