Las Baulas National Marine Park is best known for its leatherback turtles, but it also protects a patchwork of mangrove forest, tidal channels and estuary that fringe the northern edge of Tamarindo, and the best way to see that world is from a kayak. The tour we link is a guided paddle that heads into the heart of the park, away from the beach crowds and into water where the only sounds are paddle strokes, birdsong and the click of crabs among the roots. Mangroves are among the most productive habitats on the coast: their tangled roots shelter young fish and shrimp, their branches host herons, egrets, kingfishers and other waders, and the mud banks at low tide attract a parade of feeding birds. Guides know where to look for howler and white-faced monkeys, iguanas basking on branches and, with luck, a crocodile resting on the bank. Kayaks are stable, double or single, and a briefing on technique means that beginners can manage perfectly well. Tides matter in an estuary, so the operator plans the route around them, and the paddle can be gentle or quite athletic depending on the current. It is a refreshing change from beach and surf, and it gives you a different appreciation for why this stretch of coast was protected in the first place.
How it works
You book a date and time slot, and the operator meets you at a launch point near Tamarindo and fits you with a kayak, paddle and life jacket. Details such as group size, length of paddle, snacks and whether the route follows the estuary or reaches a particular channel depend on the option you choose, so read the inclusions on the ticket and confirm anything that matters with the operator.
What to expect
The route passes through calm, sheltered water with little wave action, though wind and tide can add effort on the way back. Guides stop frequently to point out birds, crabs, mudskippers and lizards, and to explain how mangrove roots filter water and protect the coast from storms.
Wildlife is never guaranteed, but early morning departures give the best chance of activity. Bring binoculars if you have them, and keep your voice low to avoid scaring animals. Crocodiles live in these waters, so follow the guide's instructions and keep hands and feet inside the kayak.
Making the most of it
Wear a hat, sunglasses with a strap and quick-dry clothes, and apply reef-safe sunscreen. A dry bag for your phone is wise. Morning trips avoid the heat and the strongest afternoon wind, and low light is better for photographs. Combine the paddle with a swim or a late breakfast in town, and with a night turtle visit if you are travelling in nesting season. If you enjoy the experience, ask the guide about other estuary and river tours, because the northwest coast has many.
Good to know
Tides shape everything in a mangrove estuary, which is why the schedule can seem odd. Paddling with the current feels effortless, while paddling against it can be tiring, and a good guide plans the outing so that the harder stretch comes early. If you have a waterproof camera, keep it on a lanyard, and avoid reaching toward branches where snakes or wasp nests may be hidden.
Footwear that dries quickly is more useful than flip-flops, and a light long-sleeved shirt prevents sunburn on shoulders and arms during hours of exposure on open water.
