Plymouth sits on England’s southwest coast, where the River Plym meets the sea, forming a wide natural harbor that has shaped the city’s identity for generations. The waterfront remains central to daily life, with views stretching across Plymouth Sound and boats moving in and out of the marina. Visitors often begin along the historic Barbican, an area of narrow streets and old buildings that survived past conflicts and now house independent shops, galleries, and small cafés.
Buck Island is a small uninhabited island off the northeastern coast of St. Croix in the U.S. Virgin Islands.

Tikal is one of the most extraordinary ancient cities in Guatemala, hidden deep in the Petén region’s tropical forests. Once called Yax Mutal by its Maya builders, these ruins reveal thousands of years of history in carved stone stelae and towering limestone structures, some of which rise more than 60 meters above the jungle floor. Today, visitors can walk among the Great Plaza and gaze up at the Temple of the Great Jaguar and the Temple of the Masks, reminders of the city’s long legacy.
Chiba, located just east of Tokyo, is a dynamic prefecture that blends modern attractions with serene coastal and rural landscapes.

One of the major rivers of the Iberian Peninsula, the Douro in north-central Spain and Portugal just might be the world's most beautiful wine region. Most of the river on the Spanish side isn't navigable, so river cruises generally travel roundtrip from Porto, on the coast of the Atlantic.
