Liveaboard Diving, Jungle Trekking & Magnificent Marine Encounters: The Ultimate Adventure in Costa Rica

Located in the heart of Costa Rica, the Central Valley is a smorgasbord of different environments including volcanic mountains, coffee plantations, dense rainforest and the capital of San Jose. There's a huge range of activities to get stuck into here - you could hike through forest reserves to spot the country's famous residents, including common pauraques, sloths and everything in between, or you might want to go white water rafting down the Pacuare river, visit a coffee plantation, or explore the active Poas volcano.

However you choose to spend your day, enjoy a delicious dinner back at your hotel before getting an early night ahead of tomorrow's adventure.

The journey takes around two-and-a-half hours, heading west, passing through Costa Rica's famed tropical rainforest and farmland. Upon arrival, you will be shown your cabin and given an orientation as the boat departs for the epic 36-hour voyage to the remote, wild Cocos Island.

The crew are incredibly knowledgeable about the area and will teach you all about the marine park and World Heritage Site. There are also videos to watch giving you a teaser of what to expect. This place is undeniably epic thanks it's incredible marine residents, from white tip, silky and silvertip sharks, marbled stingrays, manta rays, moray eels, huge schools of jacks and tuna, lobsters, sailfish, marlin, green turtles and even - if you're very lucky - a passing whale shark. The real stars of the show in this location are the scalloped hammerheads, which divers can witness in their hundreds when diving here.

If you haven't already got your Nitrox speciality, today is the perfect time to take the course, ahead of your upcoming diving adventure.

Over the next few days you'll be able to do at least three dives a day and you'll also have the option to go night diving. With 20 sites surrounding Cocos Island, you will have ample time to explore the underwater world surrounding the island.

One of the most famous sites at Cocos Island, if not in the world, is Baja Alcyone. The submerged seamount has earned its legendary status due to the huge schools of scalloped hammerheads that frequent the site, as well as the possibility of manta ray sightings. For a real exploratory adventure, join the few who have ventured to the ocean's depths in a deep-sea submersible, to spy some rarely seen deep sea creatures. There have also been sightings of tiger sharks in this area, so you might be lucky enough to catch a glimpse of this powerful fish on one of your dives.

Enjoy days of diving, followed by relaxing evenings sharing dive stories and looking forward to what the next dive will bring.

During the voyage back, take the opportunity to pick the brains of your dive guide, asking about the magnificent marine life that's visible when diving in Costa Rica - much of which you will have seen over the last few days. The guides are fountains of knowledge on the area and will be able to provide a unique insight into animal behaviour in the region.

You will be met at the hotel and transferred to the international airport in plenty of time for your flight to Golfito in the Osa Peninsula and the Golfo Dulce. The short flight takes 40 minutes and once you have landed you'll be met and transferred to your hotel.

Located on the Pacific coast, south of San Jose, the Osa Peninsula and Golfo Dulce are the perfect blend of beach and jungle. Known as 'the most biologically intense place on Earth', the Osa Peninsula boasts almost half of Costa Rica's wildlife species, as well as almost 750 species of trees - not to forget the region's sweeping beaches and mangrove swamps.

Once you've checked into your hotel, spend the rest of the day getting well acquainted with your local surroundings and relaxing after your long journey.

One of the most remote parks in Costa Rica, Corcovado National Park is an unspoiled paradise where dense forests harbour a stunning array of species, this green paradise is home to a whopping 2.5% of the world's total biodiversity. Spend the day exploring this incredible environment, hiking through the forests to find deserted beaches and stumbling across hidden inland rivers, waterfalls and lagoons.

Led by an expert naturalist, you'll paddle past thick mangroves and rainforest as your cruise along the river, spotting the tropical birds and other animals that reside here. Your expert guide will be able to answer any questions that you might have about the local flora and fauna and you'll want to make sure that you get plenty of pictures, capturing this amazing experience.

After your floating tour, head back to the hotel for a relaxing afternoon that is yours to spend as you like. You could head to the spa for a treatment, take a yoga session or take it really easy, snoozing by the pool.

As night falls this evening it's time to pull on your hiking boots, ready for a thrilling nocturnal rainforest hike. Accompanied by a naturalist, you'll be able to see the rainforest's nocturnal creatures as they arise from their slumber.

You'll arrive back at the hotel at the perfect time to enjoy a delicious dinner under the stars.

After a delicious lunch, either back at the hotel or picnicking on the beach, it's time to venture into the open ocean on a whale watching adventure. Keep your eyes peeled for bottlenose, spotted and spinner dolphins as well as humpback whales (between July and October), turtles, stingrays and if you're very lucky, false killer whales. As the sun begins to fall in the sky, the boat will head back to the mouth of the river, in time for you to see the sunset over the mountains, with a cocktail in hand.

For your final evening we can arrange a private candlelit dinner under the stars, toasting an incredible adventure exploring and diving in Costa Rica.

Your international flight will depart in the late afternoon and takes just over ten hours, landing in the UK following morning.
