You’ll hop between quiet bays and lively beach bars across St. Thomas and St. John on your own private catamaran—with time to snorkel with turtles at Maho Bay, float off Trunk Bay, and grab tacos at Lime Out before relaxing at Water Island or Magens Bay. It’s all set to island music with drinks included—and plenty of room to just be yourself.
The first thing I noticed was the way the MV Poseidon barely rocked as we climbed aboard—felt steadier than any boat I’ve been on, which honestly surprised me. Our captain, Mark, handed out cold beers right away (I took a soda, still half-asleep) and asked where we wanted to go. Someone said Maho Bay for turtles, someone else wanted Secret Harbour Beach Resort for lunch. Mark just grinned and said we’d fit it all in. The air smelled like sunscreen and salt, and the stereo played something reggae-ish that made everything feel lighter.
I didn’t expect to laugh so much at 10am but there’s something about bouncing over the water with friends that makes you forget you’re an adult. We stopped at Honeymoon Beach first—water so clear it almost looked fake—and I tried snorkeling for the first time since I was a kid. Saw a turtle glide past under me, slow and unbothered. My mask kept fogging up but honestly? Didn’t care. At Trunk Bay, we just floated off the back of the boat until our fingers wrinkled up. The sun was strong but there’s shade on the catamaran if you need it (I did).
Lunch at Lime Out was messy—in a good way. Tacos dripped down my arm and nobody minded because everyone else looked the same. There’s this easy rhythm to island days: swim, snack, repeat. At Water Island later, Mark dropped us so close to shore I barely got my ankles wet stepping off—never seen a boat do that before. Someone played “Three Little Birds” too loud but nobody complained; even the bartender at Dinghy’s just laughed and poured another round.
We never felt rushed—if anything, we probably lingered too long at Magens Bay just watching clouds drift over the hills while some local kids played soccer in the sand nearby. It’s weird how quickly you settle into doing nothing here. On the ride back I found myself thinking about that turtle again—just moving slow, not worried about anything except what’s right in front of him.
