Isla del Cano

December 8 – 16, 2018 | 8 nights

Part of the Osa Conservation Area, Isla del Cano lies 10 miles (17 km) from the western shoreline of the southern Osa peninsula in Costa Rica. This scenically stunning, biologically intense part of the country hosts what has been called the crown jewel of the national park system – Corcovado National Park – with some of the last remaining primary forests in Central America. Not surprisingly, due to its protected status and lack of human settlement, it also makes up one of the best hidden diving destinations on the continent. Allow the land and sea to overtake your senses with its grand display of pure life. You will practically be guaranteed sightings of white tip reef sharks, sea turtles, and dolphins, as well as several species of pelagic fish, barracuda, trevallys, and rays. Occasional visitors also include several species of whales, including the longest Humpback whale season in the world, and whale sharks. With white sand beaches (rare for the area), lush surroundings, and intense biological richness, it is a must-do for any nature lover and adventure enthusiast.

Day 1 | SAT. | 8 DEC

You will arrive into Costa Rica’s capital city of San Jose, sitting at an elevation of 1,172 meters above sea level. After settling into our hotel set into one of the more peaceful hillsides of the city, we will enjoy the panoramic vista and have a moment to rest, acclimate, and get to know other participants during our first evening’s Welcome Dinner.

Day 2 | SUN. | 9 DEC

The next morning, we will rise early for the adventure filled drive from San Jose to Sierpe, located in the southern zone of the country. This four-hour drive runs across the western portion of the Central Valley, traversing the famed Tarcoles river packed with crocodiles, and continuing past surf meccas and beach towns which dot the Pacific coast. The further south we travel, the more undeveloped our surroundings will be, with lush green mountains lining one side of the highway and the ocean lining the other. Once arrived at the small township of Sierpe on the banks of the Sierpe river, we will stop for lunch and transfer our belongings to a motorboat which will transport us down the river. An adventure in it of itself, the boat ride will take us down the towering mangrove-lined banks, over the dramatic river mouth meeting with the Pacific Ocean and arriving with a “wet landing” directly to our hotel with sweeping views of Drake Bay and the sea.

Day 3 | MON. | 10 DEC

We will be picked up early in the morning by boat from our hotel dock to head out for our first day of diving (two air dives) in the waters surrounding Isla del Cano. Located 15 km from the mainland, approximately a forty-minute boat ride away, this island is surrounded by fringing reefs, as well as sandy and rocky bottoms. It has enjoyed protection terrestrially as a Biological Reserve since 1976 and since 1984 for marine habitats. Hosting one of the most abundant coral reefs in the Eastern Pacific, the dive sites as varied as the species we have the potential to see. This ecologically rich and pristine coastline is waiting for you to explore its beauty. The average visibility can change daily due to currents, tides, and environmental factors, but averages 20 meters (60 ft). Common sightings include dolphins, sea turtles, white tip reef sharks, and several species of schooling pelagic and reef fish appearing as silver clouds within the water column. It is also famed as having the longest Humpback Whale season in the world, receiving both north Pacific and south Pacific pods at their respective migration times during the year. A homemade lunch will be enjoyed during our surface interval on the beach. *Please note that Nitrox (Enriched Air) is not available in any dive centers in this area.

Day 4 | TUE. | 11 DEC

The adventure is just beginning as we depart early morning for San Pedrillo Ranger Station, located within Corcovado National Park on the edge of the Osa peninsula. Having been named one of the most biologically intense places on Earth by National Geographic, the park is home to all four species of monkeys, as well as jaguars, tapirs, toucans, macaws, and more than 150 butterfly and 5,000 plant species. After another daring wet landing, led by our naturalist guide, we will trek from the beach through primary and secondary forest teeming with enough life to hold 2.5% of the world’s total biodiversity. We will stop for lunch at the ranger station after our first two-hour walkabout, continuing afterward down a second trail head taking us to a waterfall with a crystalline bathing pond. We will be back to the hotel in the late afternoon for dinner and to enjoy the grounds of our hotel.

Day 5 | WED. | 12 DEC

We will be picked up from our hotel dock once more for another two-tank dive surrounding Isla del Cano. What will the ocean hold for us today? Keep your eyes peeled for resident dolphin pods, false orcas, and devil rays jumping out of the sea into the air as the boat makes its way to our dive sites. A homemade lunch will be enjoyed during our surface interval on the beach. *Please note that Nitrox (Enriched Air) is not available in any dive centers in this area.

Day 6 | THU. | 13 DEC

After our last day of diving, we will come in for dinner before departing again for a two-hour, slow-paced night hike into the forests in the outskirts of town. Become acquainted with the amazing nocturnal fauna of the area in this popular night tour where you will be able to learn about and spot different species of insects, amphibians, reptiles, birds and mammals that are active at night. *Please note that Nitrox (Enriched Air) is not available in any dive centers in this area.

Day 7 | FRI. | 14 DEC

Our last day will be taken at leisure! Take part in a half-day horseback riding tour along the beach, with a ride up towards the hills into a small traditional Costa Rican farm. We may have the chance depending on conditions to take a refreshing dip in a natural pool located in a small river quietly hidden in the jungle. After relaxing along the river, we will ride back to the hotel. The remainder of the day can be spent leisurely in the comfort of one of many campus hammocks, taking a swim in the pool overlooking the bay, or a short hike into town.

Day 8 | SAT. | 15 DEC

We will rise early for our hotel check-out and return to San Jose via the Sierpe River. Along the way, expect to make a stop for lunch at a small black sand beach town lining the Pacific Ocean before heading into the city. The town hosts various surf competitions and is home to some of the most consistent surf breaks in the country. Once we have arrived in the city and checked into the hotel, we will have our last farewell dinner – with the opportunity to participate in some salsa dancing and live music before calling it an evening!
