Krabi, located on the southwest coast of Thailand, is known for its towering limestone cliffs, warm Andaman waters, and a coastline dotted with over 150 islands. One of its most iconic sites is Railay Beach, which is accessible only by boat due to the cliffs that cut it off from the mainland. Railay is famous among rock climbers for its natural limestone formations, some of which hang directly over the sea.

Tonga is distinctly different to its neighboring island nations. This Polynesian kingdom, made up of 170 islands, carries a proud history that dates back over 3,000 years. On the main island of Tongatapu, travelers can explore ancient stone structures like the Haʻamonga ʻa Maui Trilithon—sometimes called the Stonehenge of the Pacific. Royal tombs in Lapaha offer a glimpse into the lineage of Tonga’s kings, while village life remains guided by customs that have changed little over centuries.

Death Valley, California, is a land of extremes that captures the imagination with its striking desert landscapes and surreal beauty. Located in the Mojave Desert, it is the hottest, driest, and lowest national park in the United States. Visitors are drawn to its iconic features, such as the vast salt flats of Badwater Basin, which at 282 feet below sea level, mark the lowest point in North America.

St. Lucia is an island of verdant landscapes in every direction: A dense rain forest rises up and covers The Pitons' twin peaks, and in the valleys, the sun's rays dance upon the large yellow-green leaves of banana plants. Beyond all the greenery, you'll find isolated coves, stunning beaches, colonial towns, quiet fishing villages and first-class yachting facilities.

Guatemala is a country where ancient history and living tradition meet in unexpected ways. The ruins of Tikal, once a major center of the Maya civilization, rise from the dense Petén jungle. Visitors can climb stone temples that pierce the forest canopy and listen for howler monkeys echoing through the trees. Tikal National Park, a UNESCO World Heritage Site, contains over 3,000 structures and still holds secrets under layers of earth and vegetation.
