Manuel Antonio & Quepos
Diving in Manuel Antonio & Quepos offers a unique underwater experience along Costa Rica's vibrant Pacific coast. Unlike typical coral reef destinations, the underwater landscape here is defined by dramatic volcanic rock formations, creating a maze of pinnacles, swim-throughs, and caverns. These structures are teeming with life, providing shelter for a rich diversity of marine species. Situated right next to the world-renowned Manuel Antonio National Park, this destination perfectly blends thrilling subaquatic exploration with incredible topside rainforest adventures, making it a quintessential Costa Rican 'Pura Vida' experience.
The diving conditions are suitable for all experience levels, with most sites being a short boat ride from the Quepos marina. While visibility can be variable due to the nutrient-rich waters, this plankton bloom attracts an impressive food chain, from massive schools of fish to graceful rays and reef sharks. Divers should visit for the chance to see prolific Pacific marine life against a dramatic volcanic backdrop and the convenience of combining a dive trip with encounters with monkeys, sloths, and tropical birds just steps from the ocean.

Frequently Asked Questions
What's the most popular dive site in Manuel Antonio & Quepos, Costa Rica?
The most popular dive site is undoubtedly Bajo del Diablo (Devil's Drop). This offshore pinnacle is famous for its impressive underwater topography, featuring a series of rock pinnacles with arches and swim-throughs. It attracts a huge diversity of marine life, including large schools of snappers and jacks, white-tipped reef sharks, and various species of rays. Its depth and potential for currents make it a thrilling dive for intermediate to advanced divers, offering a true taste of Costa Rica's wild Pacific diving.
What are the good and less popular dive sites in Manuel Antonio & Quepos, Costa Rica?
Besides the famous Bajo del Diablo, 'El Acuario' (The Aquarium) is another well-known site, perfect for all levels with its calmer conditions and abundant fish life. For a hidden gem, ask dive operators about the smaller, unnamed coastal rock formations. These less-visited spots often surprise divers with unique macro life like nudibranchs and harlequin shrimp, offering a more intimate diving experience away from the main sites. La Macha is another good option known for its resident white-tipped reef sharks.
What water temperature is it like throughout the year diving in Manuel Antonio & Quepos, Costa Rica?
Water temperatures in Manuel Antonio & Quepos are generally warm, averaging 26-29°C (78-84°F). However, from December to March, seasonal winds can cause upwellings and distinct thermoclines, where the temperature can drop significantly at depth, sometimes to as low as 19°C (66°F). During the rest of the year (April to November), the water is consistently warmer. Be prepared for these temperature shifts, especially during the dry season.
When is the best time to visit Manuel Antonio & Quepos, Costa Rica?
The dry season, from December to April, offers the best surface conditions with sunny weather and calmer seas. However, the rainy season, from May to November, often brings better underwater visibility and attracts more pelagic life like manta rays and eagle rays. For whale watching, visit between July-October for Antarctic humpbacks or December-March for North American humpbacks. Essentially, there is great diving year-round, with each season offering unique advantages.
What's the visibility like during the dive season in Manuel Antonio & Quepos, Costa Rica?
Visibility in this region is highly variable due to the nutrient-rich Pacific waters. It is not known for crystal-clear conditions. Expect an average range of 6-18 meters (20-60 feet). It can change daily based on tides, currents, and plankton blooms. Often, visibility is paradoxically better during the rainy season (May-November) as coastal runoff is washed further out to sea, though surface conditions can be choppier. Check with local operators for current conditions.
Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Manuel Antonio & Quepos, Costa Rica?
Yes, the main event is the migration of humpback whales. They can be seen from July to October (southern migration) and again from December to March (northern migration). While not guaranteed on a dive, their songs are often heard underwater. Giant manta rays are more commonly spotted during the rainy season (May-November) when plankton is most abundant. Whale shark sightings are very rare but not impossible. Eagle rays and mobula rays are also more frequent during these months.
What marine life can I expect to see in Manuel Antonio & Quepos, Costa Rica?
You can expect to see abundant white-tipped reef sharks, various stingrays, and majestic eagle rays. Large schools of fish are a highlight, including jacks, grunts, and snappers. Moray eels, octopus, and sea turtles are common residents of the volcanic rock formations. For macro enthusiasts, look for nudibranchs, harlequin shrimp, and other crustaceans. The biodiversity is impressive due to the nutrient-rich waters of the Pacific coast.
What thickness wetsuit should I wear in Manuel Antonio & Quepos, Costa Rica?
A 3mm full wetsuit is generally sufficient for most of the year. However, if you are diving between December and March, a 5mm wetsuit is highly recommended. During this period, strong thermoclines can cause water temperatures to drop significantly at depth, and the extra thermal protection will ensure a more comfortable and enjoyable dive. If you tend to get cold, a 5mm suit is a safe bet year-round.
How do I get to Manuel Antonio & Quepos, Costa Rica?
Most international visitors fly into Juan Santamaría International Airport (SJO) in San José. From SJO, you have two main options. You can take a scenic 2.5-3 hour drive via rental car or shuttle bus. Alternatively, for a quicker journey, you can take a 25-minute domestic flight from SJO to the local Quepos La Managua Airport (XQP), which is just a few minutes from the main town and hotels.
Should I book a liveaboard or stay on shore in Manuel Antonio & Quepos, Costa Rica?
You should definitely stay on shore. Manuel Antonio & Quepos is exclusively a shore-based diving destination. All local dive sites are relatively close to the coast and are reached via daily day-trip boats departing from the marina in Quepos. There are no liveaboards that operate in this specific area; liveaboard diving in Costa Rica is primarily focused on the remote and world-famous Cocos Island, which is a completely different trip.
