Prepare yourself for an immersive 5-day adventure in one of the most biodiverse places on Earth: the Osa Peninsula in Costa Rica.
Why did we specifically choose to go to this remote area ? Want to reconnect with nature, stay away from the crowds? Learn more about biodiversity ? Enjoy some fun outdoors adventures? Lets' tell you more.
The Osa Peninsula has been highlighted by National Geographic as 'one of the most biologocal intense place on Earth'
The Osa Peninsula is one of the most isolated and less-developed regions of Costa Rica.
It is a raw, remote with an untamed landscape surrounded by rugged mountains, dense rainsforests, but it is also a destination that is world-famous for its incredible biodiversity and pristine coastline. Just the perfect place to reconnect with nature!
So whether you're an intrepid explorer or just seeking peace amidst nature’s most majestic creatures, the Osa Peninsula offers it all.

With it's unique ecosystem where the rainforest meets the Pacific Ocean, this small strip of land, spanning about 1,800 square kilometers (700 square miles), is estimated to be home to 2.5% of global terrestrial biodiversity.
Day 1: Dive into the Wilderness
As soon as you touch down at Puerto Jimenez airport, no more than just a landing field or so, you instantly get a sense of where you've arrived. The sounds of the jungle surround you with parrots squawking, giant insects screeching, and monkeys howling right at your feet!

Arrival in Puerto Jiménez: Begin your journey with a flight to Puerto Jiménez, the gateway to Corcovado National Park.
This 15-seater aircraft operated by Sansa airline sets the tone for an epic adventure right from the start, soaring toward a remote, bush-like airstrip where it touches down.
Upon arrival, pick up your rental car across from the airstrip unless you have arranged a car transfer to your accommodation.

First Encounter with Nature: After settling in, we took a short hike through the surrounding rainforest listening to the sounds of the jungle. Expect to hear howler monkeys calling from the treetops, toucans squawking, and the distant chant of exotic birds.
We stayed the first night in Puerto Jimenez at the Botanika Hotel. It is conveniently located and was a good base to start planning our outdoor adventures for the coming days.
Beach sunset bliss: In the evening, enjoy sunset on one of the secluded beaches nearby andn stop by Los Delfines, a waterfront restaurant located a mile away from the hotel, to enjoy some delicious seafood.

Day 2: Experience deep-sea fishing
From the hotel, we booked a deep sea fishing tour the next morning to discover the coastline from another view point and hoping to catch some mahi mahi!

Morning deep sea fishing tour
Although it wasn't the season for marlin, there was a high chance of catching some mahi-mahi.
The kids were thrilled to try the experience, though we just wanted to make sure they could handle the catch!
By the time we reached deep water, about five miles from the coast, the fun could finally begin. Suddenly, the lines started to shake and tremble, and the fight was on!
Enjoy a deep-sea fishing excursion and let the hotel prepare your fresh catch for a delicious dinner.

Everyone was able to take the fight with some little help! At the end, we've decided to keep only one fish for dinner and release the other ones...
Early afternoon, we headed deeper in the Osa peninsula for our next adventure.
Once you get back from the tour around lunch time, ask your hotel to wrap the fish with ice and hit the road heading to your next destination - Cabo Matapalo.
Our next hotel, called Encata La Vida Lodge, was kind enough to prepare our catch of the day: we enjoyed a delicious ceviche as a starter, followed by a slow-cooked fish recipe for the main course!
Day 3: Hike the Corcovado National Park
The Osa Peninsula is also home to the Corcovado National Park accounting alone for 2.5% of the world’s biodiversity - a total of 250,000 species - including more than 500 species of trees, 140 species of mammals, and over 400 bird species!

Explore the Biodiversity
Today is dedicated to exploring the famous Corcovado National Park, one of the most biologically rich places on the planet.
We went on a full-day hike, guided by an expert naturalist who will help spot some of the park's incredible wildlife.
Look out for scarlet macaws, capuchin monkeys, jaguars (if you are lucky), Baird's tapirs which roam the trail, and a variety of amphibians, insects, and tropical plants some of them are endemic to the peninsula.

Guided Trek through Corcovado:
There are 6 entrance point to the Park: San Pedrillo, Sirena, La Leona, El Tigre, Los Planes, and Los Patos.
We drove 30 minutes from Matapalo to Carate on a dust road. Once you arrive there, you will have to walk 3km along the beach to reach the park entrance at La Leona station.
Start hiking the Madrigal trail through secondary forest until you reach the Hedionda creek where you can stop for a lunch break. At this point either you turn back or continue until La Sirena station,... but you will need to book a lodge to stay overnight. We went for the shorter hike but still saw tons of wildlife!
Our local guide was very knowledgeable about the wildlife and knew where to spot animals, amphibians insects, and endemic plants.

The Corcovado National Park is a sanctuary for animals such as jaguars, pumas, tapirs, and scarlet macaws—species that are increasingly rare in other parts of the world.
The day is now over and we spent the day reviewing our pictures and discussing this memorable day.
Day 4: Water Rappelling and outdoor adventure
When we visited the Osa Peninsula, it was right at the tail of the rainy season, so it was still very wet with rivers roaring! A good time to try some water rappelling!

Morning Waterfall Rappelling Adventure:
Gear up and make your way through the dense forest to reach one of the beautiful waterfalls that cascade down the mountains of the Osa Peninsula.
Here, you'll rappel down waterfalls for around two hours in a narrow canyon surrounded by lush surroundings.
It's an exhilarating experience, as you descend the waterfalls, feeling the rush & power of water all around you.
You will end the tour walking down the creek until you reach the beach. The tour and gear are provided by El Remanso lodge set within its private estate.
After some water rappelling, should we grab our boards and try to catch the waves?

Afternoon surfing on a secluded beach Later, head to one of the nearby secluded beaches for a surf session.
There are few spots on the peninsula from beginners to advanced, but we went for the easy waves on Playa Pan Dulce.
Whether you’re a skilled surfer or a beginner, the waves here are perfect for riding all year round with the best time being from March to October.
If you prefer something quieter, simply lounge on the beach, taking in the serenity of the surroundings.

Evening in the Jungle: As night falls, you might catch a glimpse of the nocturnal wildlife coming alive. Listen to the sounds of owls, frogs, and insects, and let the jungle's nocturnal symphony lull you to sleep.
Day 5: Reflection & Departure
It's time to leave and drive back to Puerto Jimenez to catch the return fligh for San Jose.
We will remember the unparalleled biodiversity of the Osa Peninsula and the Corcovado Park, the secluded beaches and all the jungle adventures from hiking to water-rappelling. It's the perfect trip for those wanting to reconnect with nature and truly immerse themselves in a place that feels very much untouched.
