Best Things to Do in St. Thomas With Kids
St. Thomas's best family days are Magens Bay (the beach that ends every 'best beaches' list), Coral World Ocean Park's underwater observatory and touch pools, Coki Beach's easy reef snorkeling right next door, the Paradise Point Skyride for harbor views, and a sailing/snorkel day out to Water Island or St. John.

A mile-long, gently curving beach with some of the calmest water on the island — repeatedly ranked among the best beaches in the world, and it earns it. Shade, food trucks, and chair/float rentals make it an easy, low-effort full day with toddlers through teens.
Watch out: Gets crowded when cruise ships are in port — go early. The small entrance fee is per person, and parking fills up by mid-morning.

An actual marine park, not just a gift shop with fish tanks — touch pools, a walk-down underwater observatory tower with reef views, sea lion and shark exhibits, and turtle feedings. Add-on experiences like Sea Trek (helmet diving that doesn't require swimming) work for kids as young as 8 who can't yet snorkel confidently.
Watch out: Add-on experiences (Sea Trek, snorkel excursions) cost extra on top of general admission and have age/weight minimums — check before you promise a specific add-on to the kids.

Right next door to Coral World, and one of the easiest reef snorkels on the island — shallow, protected water with fish so used to visitors feeding them that they'll practically swim up to your mask. A cheap, no-boat-required way to see real reef life.
Watch out: It's a public beach with vendors and can get crowded and a little chaotic with cruise-ship traffic; watch belongings. Feeding fish is a local tradition but stick to fish-safe food (frozen peas), not chips or bread.

A short aerial tram ride up to a lookout over Charlotte Amalie's harbor and cruise ships below — no hiking, no boat, just a fast, scenic win when everyone's tired. There are shops, a small nature trail, and a bar at the top.
Watch out: The view is the whole activity — don't expect more than an hour here. Best paired with lunch or shopping in Charlotte Amalie right below.

A catamaran sail out to a quieter beach — Water Island's Honeymoon Beach or a St. John stop — with a snorkel break along the way. It's the best way to get open water and a change of scenery from the main-island beaches without a long ferry commitment.
Watch out: Choppier open-water crossing than a resort pool day — pack sea-sickness remedies for kids prone to motion sickness. Confirm whether lunch and gear are included before booking.
Frequently asked
Do we need a passport to visit St. Thomas?
No, not for US citizens — St. Thomas is a US territory, so a passport isn't required for domestic flights, though you'll want a government ID.
Is Magens Bay or Coki Beach better for snorkeling?
Coki Beach, hands down — it's shallower, calmer, and has more visible reef fish right off the sand. Magens Bay is the better beach for swimming and lounging, not snorkeling.
How many days do families need on St. Thomas?
Three to four days covers Magens Bay, Coral World/Coki, Paradise Point, and one boat day at a relaxed pace.
Is Coral World worth it if we're already snorkeling at Coki Beach?
Yes — they're different experiences. Coral World guarantees sightings (sharks, sea lions, the observatory) regardless of ocean conditions, where wild snorkeling depends on visibility and luck.
