Pack your sense of adventure and head to Costa Rica’s west coast for a spectacular, sustainable vacation.

Guanacaste has been an eco-tourist haven for decades.

If you haven’t been to Guanacaste, be warned: it may change you forever. 

For the eco-traveler, Guanacaste is a playground of natural places to explore with extraordinary biodiversity. It’s one of the world’s most pristine stretches of wilderness where you can observe wildlife and immerse yourself in different terrains and enjoy a variety of activities in a sustainable way.

Eco-vacations have skyrocketed in popularity recently as travelers discover how responsible travel helps local communities and economies. And travelers have also discovered, to their delight, that eco adventures are even more satisfying and enriching than their more traditional trips.

Costa Rica is renowned for its commitment to ecotourism principles and its leadership in ecotourism initiatives, setting standards that the rest of the world follows.

This commitment to ecotourism in Costa Rica has been fundamental in protecting Guanacaste’s natural spaces, turning them into parks, reserves and refuges, and also initiating programs that enrich local communities.


Guanacaste is diverse and filled with natural beauty.

Spanning over 10,000 square miles of varied climates and terrain, the province of Guanacaste stretches from the west coast to La Fortuna and from the northern border with Nicaragua down to the Nicoya peninsula.

Packed with parks, beaches, volcanoes, caves and charming little towns, Guanacaste is full of opportunities to hike, swim, surf, snorkel, visit caves, birdwatch or just bask on one of the many pristine beaches.

Guanacaste’s Treasure: the National Parks

Full of beauty and adventure, Guanacaste’s national parks offer full immersion into nature.

Guanacaste’s national parks and reserves are extraordinary. Each offers a unique experience to duck out of civilization and dip into nature for a good break. Adventures Under the Sun incorporates Guanacaste’s national parks into our itineraries on a regular basis, and we know them well. 

In the parks, see plants and animals unique to the region, volcanoes and vistas renowned throughout the world, forests, rivers, streams and so much more. Here is a list of some of our favorite parks.

Palo Verde National Park

Palo Verde supports an impressive variety of plants and animals, including a number of endangered species and over 300 species of birds. It’s no wonder that this park is renowned for its birdwatching, so be sure to pack your binoculars!

From dry forests to wetlands, Palo Verde is perfect for adventuring with numerous hiking trails that wind through varied terrain. Always exciting and fun!

Rincón de la Vieja National Park

Rincón de la Vieja spans an area that includes dry forests, wetlands, and volcanic areas , with hiking trails to suit all levels, from easy hikes to more challenging ones. You’ll also find hot springs and gorgeous waterfalls along the way to enjoy. Notably, the Oropendola Waterfall and hike nearby is a favorite for any traveler visiting Costa Rica!.

Arenal Volcano National Park

The views of Arenal Volcano and the surrounding landscape are stunning, and a big draw for visitors. The views are easily accessible from the many hiking trails, some of which lead to Arena’s wonderful hot springs.

In the park, you’ll also find a wide variety of interesting plants and animals, as well as Arenal Volcano, one of Costa Rica’s most active.

Barra Honda National Park

If you’re interested in caves, breathtaking Barra Honda National Park is a must. This park is famous for its system of naturally formed underground caves, shaped by erosion over millions of years. They’re a rare, unique and fascinating natural wonder not to be missed.

When touring the caves, you’ll hike to the cave entrance, then drop down into the caverns (with provided headlamps and helmets). You’ll learn about the geology and history of the caves, as well as the plants and animals that manage to thrive in that environment.

Guanacaste’s parks committed to research and conservation

In addition to their natural beauty, the national parks of Guanacaste are also home to a number of research and conservation initiatives, making them an important destination for those interested in sustainability and environmental protection.

Guanacaste has a beach for every mood.

We love hosting whitewater rafting trips on this exciting river, and many of our adventurers enjoy including a stop at the Golden Bean Plantation to keep everyone’s energy up as we explore and challenge ourselves in the great outdoors.

While known for its rafting, there are also lots of other activities to experience in the region.

Can Guanacaste boast for a minute? It is home to some of the most beautiful beaches and crystal clear waters in all of Costa Rica.

Guanacaste has drawn surfers for decades with amazing waves and perfect surf spots. The sand is pristine, the water is clear, and the sun is warm.

Animals in Guanacaste

If wildlife is your thing, you’ll fall in love with Guanacaste’s unique and varied wildlife, including a number of species not found anywhere else.


Monkeys are playful, and Guanacaste’s troops can be seen in the trees and often heard echoing across the mountains as one groups talks to another. During your journey, you may see howlers, capuchins or maybe even spider monkeys.  Remember – please do not feed the wildlife!


Adorable sloths are one of the most iconic animals of Costa Rica, with their graceful, slow movements and distinctive coats. Depending on your location you may see the two or three toed sloths…  Keep your eyes peeled, they are not easy to spot.


Costa Rica is unparalleled when it comes to birding, and Guanacaste is home to some of the most spectacular birds on the planet, including toucans, parrots, and a variety of tropical birds.

Many other species will migrate to Costa Rica for the winters. Keep an eye out for brightly colored birds while exploring the region, especially the Roseate Spoonbill or Long-tailed Manakin.


Lizards abound all over Costa Rica, soaking up the sun and hiding in the rocks. Guanacaste is home to a number of different species of lizards and snakes (not all are harmful!), including iguanas and anoles. Look for them sunning on rocks or branches, or scooting away as you walk by.
