A major industrial area in the Loire Valley, it is an ancient city and was often visited in pilgrimages to pay homage to the tomb of St. Martin, a former bishop of Tours.

The Whitsunday Islands sit in the heart of Australia’s Great Barrier Reef, where more than 70 islands rise from wide blue seas and offer an invitation to explore. Whitsunday Island itself is the largest of this group, known internationally for its ribbon of white silica sand stretching over seven kilometers at Whitehaven Beach. This sand feels cool underfoot even in warm sunshine because it’s made of nearly pure silica carried there by ancient ocean currents.

Lake Powell, stretching across the Utah-Arizona border, is one of the largest manmade reservoirs in the United States. Formed by the flooding of Glen Canyon after the completion of the Glen Canyon Dam in 1963, it covers over 180 miles in length and contains nearly 2,000 miles of shoreline, more than the entire West Coast of the U.S. Despite its modern origins, the area has long been home to the Ancestral Puebloans and later Navajo communities.

Jellyfish Lake is a shadowed oasis hidden among the mushroom-like Rock Islands of Palau. This forest‑fringed saltwater lake invites visitors to float with millions of gentle, stingless jellyfish that glow like drifting amber clouds under emerald light. The lake formed about 12,000 years ago, when rising seas flooded an ancient reef basin that was gradually cut off from the ocean. Over centuries, its jellyfish evolved in isolation, shedding their stings and multiplying without predators in sight.

Bonaventure Island is a small island off the coast of Percé in Quebec's Gaspésie region, within the Parc national de l'Île-Bonaventure-et-du-Rocher-Percé.
