The Pacific off Manuel Antonio is not just a backdrop for beach photos. It is part of a marine corridor along the Central and South Pacific coast of Costa Rica that attracts humpback whales, several kinds of dolphin, sea turtles and plenty of seabirds. A whale and dolphin watching trip puts you on a boat in that water, with a guide who knows where to look and what the behaviour of the animals means. This option adds snorkeling, which makes it a broader day on the water than a pure watching trip, and it has earned a rating of 4.8 from nearly forty reviews. Humpback whales visit this coast in two seasons because the populations from the northern and southern hemispheres each travel to the warm tropical water to breed and give birth. As a general guide, the southern hemisphere whales are present from about July to October, and the northern hemisphere whales from about December to March, so the visiting window is wide, though the best months and the numbers vary from year to year. Dolphins, including spotted and bottlenose, are present throughout the year, and a boat trip in the green season still has a good chance of seeing them. Nothing is guaranteed, because these are wild animals and the ocean has its own schedule, and a good operator will say so honestly.
What the day looks like
A typical outing leaves from the Quepos marina or a nearby departure point in the morning, motors out past the headlands of the national park and spends a few hours searching the open water. When a whale or a pod of dolphins is spotted, the captain slows down and approaches carefully, following rules designed to keep the animals undisturbed.
There is usually a stop at a sheltered spot for snorkeling, and many trips include drinks, fruit or a light meal. Check the operator's description for what your option includes and how long you will spend on the water, because trips of this type commonly run for several hours.
Responsible watching
Choose an operator that keeps a respectful distance, never chases the animals and follows the local rules. If whales approach the boat of their own accord, the captain will usually stop the engine and let them pass. Never ask a guide to get closer than is safe, and do not try to touch or feed any animal. In the water, snorkeling happens in a different place from the whale watching, and you should not enter the water near whales.
What to bring and how to prepare: sunscreen that is reef-safe, a hat, polarised sunglasses, a light waterproof jacket for spray, a towel and a camera with a strap. If you are prone to seasickness, take a remedy before departure and sit near the centre of the boat, because the open ocean is rougher than the estuary or the sheltered bays near Manuel Antonio. A morning start offers the calmest water in most seasons.
Book early in the whale season, from July to October and December to March, because boats can fill up, and remember that tours can be rescheduled if the sea is rough. Pair the trip with the park on a different day, but do not plan it for the day before an early flight, in case the schedule runs long.
