📋 Best Things to Do in St. Thomas with Kids
🏖️
Magens Bay Beach
Magens Bay is consistently listed among the most beautiful beaches in the world — and it earns it. The beach is long, wide, and sheltered by hills on both sides, which keeps the water exceptionally calm and shallow. It’s ideal for young kids who want to swim without waves. Chair and umbrella rentals are available, there’s a snack bar and restaurant on site, and the surrounding scenery is genuinely stunning.
For most families visiting St. Thomas, Magens Bay should be the anchor activity. It is about 20–25 minutes by taxi from the cruise pier, and there is a per-person entry fee at the gate, charged at a higher rate for visitors than for residents. Bring cash for it.
💡 Tip: Go early. Magens Bay gets crowded on busy cruise days. Arriving within the first hour of port time gets you first pick of chairs and the best experience.
🐬
Coral World Ocean Park
Coral World is a marine life park on the northeastern tip of St. Thomas. The underwater observatory lets you descend below the surface and watch Caribbean reef life through panoramic windows. There are stingray pools, a shark habitat, sea turtles, a nature trail through native plants, and interactive animal feeding experiences. For families with younger kids or those who aren’t strong swimmers, Coral World delivers a rich marine experience without needing to get in the water.
💡 Tip: Book tickets online before you sail for a small discount. Allow 2–3 hours minimum. Coral World is on the eastern end of the island — about 30 minutes by taxi from the cruise pier. It pairs well with adjacent Coki Beach for snorkeling.
🐟
Snorkeling at Coki Beach
Coki Beach is right next to Coral World and has some of the best snorkeling accessible directly from shore in St. Thomas. The reef starts just feet from the beach in shallow, calm water. Fish variety is excellent and the water is clear. Gear rental is available on the beach. For families where the kids want to snorkel and the adults want to watch from shore, Coki is nearly perfect.
💡 Tip: Combine Coki Beach with Coral World since they’re right next to each other. Keep an eye on belongings and agree on gear rental prices before you take anything.
🚠
Paradise Point Gondola & Views
The Paradise Point gondola rides up the hillside directly from near the cruise pier and delivers panoramic views over Charlotte Amalie harbor, the cruise ships, and the surrounding islands. Kids genuinely love the gondola itself. The views are postcard-perfect and it’s an easy add-on to a shopping morning near the pier.
💡 Tip: Best done in the morning before clouds roll in over the hills. The ride takes about 5 minutes each way.
🛍️
Charlotte Amalie Shopping & Forts
Charlotte Amalie is St. Thomas’s main town — walkable from the cruise pier and one of the Caribbean’s premier duty-free shopping destinations. The $1,600 per-person duty-free allowance makes it genuinely attractive for parents. For kids, Fort Christian (a 17th-century Danish fort right at the waterfront) is a quick and interesting stop, and the colorful Danish colonial architecture makes for a nice walk.
💡 Tip: Shopping is best earlier in the day before the heat peaks. The covered Vendors’ Plaza near the waterfront has local crafts and souvenirs at better prices than the main jewelry stores.
⛴️ Day Trip: Trunk Bay on St. John
✨ Is the St. John ferry worth it with kids?
Trunk Bay on St. John is widely considered one of the most beautiful beaches and snorkel spots in the entire Caribbean — a National Park beach with a marked underwater snorkel trail and stunning clear water. If your family loves snorkeling and you have enough port time, it’s worth the trip.
The honest caveat: the logistics add up. Taxi to Red Hook, ferry to Cruz Bay, taxi to Trunk Bay, reverse it all on the way back. Budget at least 6 hours of port time and don’t cut it close.
Step 1: Pier → Red Hook
~30 min taxi from cruise pier. Ask for the St. John ferry dock at Red Hook.
Step 2: Ferry to Cruz Bay
~20 min crossing, running frequently. Budget roughly $8 per person each way and bring cash; published fares vary by operator, so check the current rate at the dock.
Step 3: Cruz Bay → Trunk Bay
~15 min taxi from Cruz Bay ferry dock. The National Park amenity fee is $5 per person aged 16 and up, and under 16s are free. Card is preferred at the booth.
Step 4: Reverse it all
Leave Trunk Bay with at least 90 min before all-aboard. Don’t cut this close.

⏱️ What Actually Fits in Your Port Day
A 4-hour port day
Short call
Stay close. The gondola and a walk through Charlotte Amalie, or a quick run to Magens Bay if you move fast. St. John is off the table entirely.
A 6-hour port day
Common length
Magens Bay for the bulk of it, or Coral World and Coki Beach together since they sit side by side. Pick one side of the island and stay there.
An 8-hour port day
Long call
The only length where Trunk Bay makes sense. Otherwise Magens Bay in the morning and shopping downtown after, with time to spare.
With toddlers
Under 5
Magens Bay. Sheltered, shallow and calm, with facilities on site and a short taxi back. Skip the ferry day completely at this age.
With school-age kids
Roughly 6–12
Coral World then Coki Beach is the strongest pairing: they see the fish through glass first, then snorkel with them. Both in one taxi trip.
If it rains
It happens
Coral World has covered areas, and Charlotte Amalie is a genuinely good rainy-day port thanks to the shopping and the forts.
📌 Honest Tips for Families in St. Thomas
Taxis are shared vans — this is normal.
St. Thomas taxis are often open-air safari-style trucks or vans that pick up multiple passengers going the same direction. It’s completely normal, the prices are set per person per destination, and it’s part of the island experience.
Mornings are the best time for beaches and activities.
St. Thomas gets hot quickly and afternoon clouds can roll in over the hills. The best light and best water temperature at Magens Bay or Coki Beach is in the morning. Get off the ship early and save shopping for the return.
The duty-free allowance is genuinely good.
At $1,600 per person duty-free (vs. $800 at most other Caribbean ports), St. Thomas is legitimately one of the best shopping ports in the Caribbean. Main Street in Charlotte Amalie has the most concentrated shopping. The usual requirement to have been away 48 hours does not apply to the USVI, which is what makes the allowance usable on a single port day.
If you’re going to St. John, leave more time than you think.
The St. John trip is wonderful but the logistics are genuinely multi-step. Give yourself at least 90 minutes back to the ship from Trunk Bay. Families who miscalculate the return trip end up rushing and stressed.
Your US phone plan works normally here.
As a US territory, St. Thomas is covered by most US domestic phone plans. You can use Google Maps, look things up, and stay connected without international charges.
💡 What to skip
The Skyride to Paradise Point is fun but optional — skip it if you’re short on time. The beaches at the cruise pier area are not representative of St. Thomas at its best — get in a taxi and go to Magens Bay. And don’t try to do both Coral World and St. John in one port day unless you have 8+ hours — it’s too much with kids.
