Boasting glittering white-sand beaches and dotted like pearls in the vast blue Caribbean Sea, Rosario (one of the prime highlights of Colombia) is an archipelago of 27 small coral islands, just minutes away by boat from the vibrant colonial town of Cartagena.

Tucked away in the northeastern part of Costa Rica, Tortuguero National Park (one of the key highlights of Costa Rica), and possibly one of the finest national parks of the country, is an ecological treasure-trove luring nature-seekers around the globe with its unadulterated elements and exotic wildlife.

After telling you all about Costa Rica's beaches and national parks, it's time to list out its hidden and beautiful waterfalls that attract travelers from over the globe. 

Located in the fertile northern lowlands of Costa Rica, Arenal Volcano National Park, one of Costa Rica's premier highlights, spearheads the country's tourism scene by offering an abundance of thrill-junkie adventure activities and the stuff of dreams for even the casual sightseer.

A strong rival the Arenal Volcano National Park is undoubtedly the Poas National Park, home to the eponymous Poas Volcano, and also a prominent highlight of Costa Rica. Of the six active volcanoes calling this miniature-sized nation home, Poas is arguably the most active of them all.

Costa Rica, a tiny country by any yardstick (just about the size of West Virginia) holds 5% of the world’s biodiversity; almost 25% of its land is protected by wildlife parks or game reserves, each of which offer a different kind of experience; some showcase magnificent wildlife viewing, while others provide scenic displays of tropical volcanoes and waterfalls.
