Yes—Tobago Cays is worth a full, weather-flexible boat day for its turtle snorkeling, shallow lagoon and beaches; it works best when you book a boat that gets you there early and confirms the park fee and safety plan.
Book the boat, then confirm inclusions
Arrange a licensed water taxi, day tour or charter from Union Island or Mayreau, and ask in writing whether the TCMP fee, snorkel gear, life jackets, Baradal turtle stop, beach landing, lunch and weather-cancellation terms are included.
MorePay or confirm the XCD 15 park fee
TCMP charges XCD 15 per person for up to 24 hours in the protection zone; organized-trip guests should have the captain confirm whether it is included or must be paid through TCMP PAY before arrival.
MoreArrive only by boat
There is no ferry, road, airport, dock or pedestrian entrance on the cays, so use a water taxi, day-tour boat, charter yacht, private yacht or cruise excursion.
MoreLeave early and keep a weather buffer
Ask for an early departure to reach Baradal before the late-morning boat concentration, and do not schedule an onward flight the same evening because sea conditions and squalls can cancel crossings.

Petit Bateau
~60 min · Reached by boat within the marine park; its east beach has shallow water suited to beginning snorkelers.
Jamesby
~45 min · Reached by boat within the marine park; beach landing and short informal shore walks depend on conditions.
Horseshoe Reef
~45 min · Access by boat and snorkel; use only suitable conditions, as exposed areas can be choppy and are better for experienced swimmers.
Petit Tabac
~45 min · Optional boat stop outside Horseshoe Reef; landing depends on the captain's route and sea conditions.
Tobago Cays is a small, uninhabited group of five cays—Petit Rameau, Petit Bateau, Baradal, Jamesby and Petit Tabac—and the surrounding lagoon, seagrass and reef within Tobago Cays Marine Park, east of Mayreau. Four cays sit inside Horseshoe Reef, while Petit Tabac lies outside it. Protected first as a fisheries conservation area in 1987 and established as a marine park in 1997, this 50-square-kilometer marine landscape protects coral, conch, lobster, iguanas, nesting birds and green and hawksbill turtles; it exists as a national park rather than a developed resort island.
This is the Grenadines’ signature water-based landscape: turquoise shallows, reef snorkeling, sandy cays and turtle viewing around Baradal. It is most rewarding for swimmers, snorkelers and boat travelers who can spend several hours moving between the turtle area, Petit Bateau’s calmer beginner-friendly east beach and the reef. Skip it if you need step-free facilities, dislike small-boat transfers or seasickness, or want restaurants, shops, roads and a serviced beach.
Before you go
There is no timed entry ticket, gate, ticket office, or advance park-entry reservation. However, Tobago Cays Marine Park (TCMP) charges an entry fee of XCD 15 per person for up to 24 hours in the protection zone; its schedule also lists XCD 5 per person for “local excursion” visitors. For an organized day trip, ask the captain before paying whether the XCD 15 TCMP fee is included or will be collected separately. TCMP PAY can issue an emailed receipt/QR code that rangers may check on arrival. Fee | Payment/update
You can reach Tobago Cays only by boat: water taxi, day tour, charter yacht, private yacht, or cruise-ship excursion. There is no airport, road, bridge, car access, public dock, or scheduled public ferry to the cays. Union Island is the most practical independent-traveler base, about five nautical miles away, with the widest choice of boat services; Mayreau is another nearby departure point. Arrange a licensed boat before arriving rather than expecting transport at the cays.
Confirm in writing: departure point and time; whether the TCMP entry fee is included; whether masks, fins and life jackets are supplied; whether the itinerary includes Baradal’s turtle area, a beach landing and snorkeling time; whether lunch and drinking water are included; maximum passenger count; sea-condition limits; and the cancellation, refund, and rebooking policy. Prioritize an early departure from Union Island or Mayreau to reach Baradal before the late-morning day-boat concentration. A boat’s weather window and capacity—not park tickets—are the usual limiting factors.
An independent booking service advertises Union Island private/shared Tobago Cays speedboat trips from US$330–600 total round trip, varying with group size and itinerary. This is transport/guiding, not park admission, so confirm the TCMP fee and inclusions before paying. Booking
Allow at least 4–5 hours on site, plus boat transfers. A better first visit is a 6–8-hour day trip from Union Island or Mayreau, with time for the Baradal turtle area, shallow snorkeling at Petit Bateau, and a beach stop. The best version is an overnight aboard a yacht or charter boat, which gives you quieter early morning and late afternoon; there is no accommodation ashore.
February through April are the strongest all-round months for dry-season sailing, swimming and snorkeling, though trade winds can make the water choppy and boat traffic is high. May is a useful shoulder month. June through November brings more showers, squalls, and tropical-weather disruption; September and October are the least dependable months for a fixed-date boat trip. December improves as dry-season conditions return, but Christmas and New Year are busy. Do not force a crossing in unsafe sea conditions, thunderstorms, or a tropical system.
