Dominica, known as the “Nature Island of the Caribbean,” is a haven for eco-tourists and adventure seekers. Nestled between the French islands of Guadeloupe and Martinique, this lush island boasts a remarkable landscape of volcanic mountains, dense rainforests, and stunning waterfalls. Dominica’s most iconic natural wonder is the Boiling Lake, the second-largest hot spring in the world.

Hidden in the northern region of Costa Rica, the Celeste River (Río Celeste) winds through Tenorio Volcano National Park with a color so vivid it seems unreal. The river’s striking turquoise hue is caused by a natural chemical reaction between two mineral-rich streams, Quebrada Agria and Río Buena Vista, which merge at a point known as "El Teñidero." This one-of-a-kind phenomenon creates the illusion that the water has been dyed blue, even though no pigments are present.

Castries, St. Lucia's capital and a busy port city, is an idyllic Caribbean wonderland. Tourists will find craft and fruit markets, photo-ready murals and a general cozy charm here. One must-do activity is getting to the top Morne Fortune (Hill of Good Luck) to drink in the lovely panoramic views. Be sure to visit the museum at Derek Walcott Square, and soak up the sun on Vigie Beach!

Fraser Island, or K’gari as it is known to its Traditional Owners, the Butchulla people, is a gem off the coast of Queensland, Australia. The world's largest sand island, stretching over 120 kilometers, is a place where nature dazzles and adventure beckons. Renowned for its unique ecosystems, Fraser Island offers a diverse landscape of lush rainforests growing on sand, crystal-clear freshwater lakes, and expansive sand dunes.

Martha’s Vineyard, located just seven miles off the coast of Cape Cod, feels like a world apart. This island has long attracted artists, presidents, and vacationers seeking something quieter than the mainland. With six distinct towns, each with its own style, visitors can explore everything from the stately streets of Edgartown, once a prosperous whaling port, to the laid-back vibe of Chilmark, where stone walls and sheep pastures stretch to the sea.
