Tortuga Island from Jaco

Tortuga Island is the postcard beach day of this region. The small island sits in the Gulf of Nicoya, off the Nicoya Peninsula, with a crescent of white sand, turquoise water and palm trees leaning over the beach. The full-day trip linked here is designed for visitors based in Jaco: a road transfer carries you to the departure point on the gulf, a boat crosses to the island, and the day is spent swimming, snorkeling, walking the sand and eating a long lunch. Many trips also include extras such as banana-boat rides, kayaks or paddle boards, and some stop at a secondary cove with excellent snorkeling. The appeal is simple. After the energy of Jaco, an island with calm, clear water and no traffic feels like a different country. The snorkeling is gentle, with small tropical fish around the rocks at the edges of the bay, and the water is warm and shallow near the beach. Dolphins sometimes accompany the boats, and seabirds are common along the route. Meals are normally served on the island and often include fresh fish or chicken, rice, salad and fruit, with soft drinks included, so the day is easy and social without any planning.

Be realistic about the logistics. From Jaco, the trip begins with an early pickup, a drive of well over an hour to the gulf departure point and a boat ride of around an hour, and the return follows the same route in the afternoon, so the day is long.

Seasickness can affect sensitive travellers on the boat, so take medication in advance if you are prone, sit near the rear or middle and stay hydrated. Operators run groups of various sizes, from large catamaran-style groups to smaller boats, and the vibe changes accordingly, so choose carefully if you prefer quieter days.

Check what is included before you book. Park or island access fees, lunch, drinks, snorkel gear and activities vary by operator and package, and some trips charge extra for kayaks or banana boats. Bring sunscreen, a hat, a swimsuit, a towel, water shoes and a waterproof bag, and wear reef-safe sunscreen to protect the coral.

The sun is strong on the water and there is limited shade on parts of the beach. The dry season, from December to April, is the most reliable season for calm seas and clear water, while the green season, from May to November, can bring rougher conditions and visibility changes.

The trip suits couples, families with older children and groups of friends who want a relaxed beach day. If you prefer a private experience, a private boat tour is available separately from Jaco, with snorkeling and meals, and it gives you more control over timing and pace. Otherwise, treat the group trip as an easy, fun escape that pairs well with a slower day after, and keep expectations realistic: this is a beach day with a long journey on either side, not a hidden wilderness.

For those travelling with children or older relatives, a few small tips make the day smoother. Bring snacks for the road transfer, a hat for each child, a spare dry shirt and plenty of water. Ask the operator about the boat's life jackets and the landing, which can involve stepping from the boat into shallow water. If the group is large, move away from the crowd along the beach to find a quiet spot, because the island has several shaded corners that are calmer than the main lunch area.
