Tintagel is a village on Cornwall's north coast, set among rugged cliffs overlooking the Atlantic Ocean. The area is best known for Tintagel Castle, whose remains occupy a dramatic headland connected to the mainland by a footbridge. The village itself has a traditional Cornish character, with stone buildings, small shops, cafés, and places to stay along the main road.

Adak Island lies in the central Aleutian Islands of southwest Alaska, where steep volcanic mountains meet the North Pacific. The community of Adak occupies a sheltered harbor on the island and is one of the few remote Aleutian locations accessible by commercial airline. Much of the island consists of open tundra, rugged slopes, coastal wetlands, and rocky shorelines shaped by strong winds and frequent rain.

Antipaxos is a small Ionian island southeast of Paxos, separated from its larger neighbor by a short boat journey from Gaios. Covering roughly 4.5 square kilometers, it has a gently rolling landscape of vineyards, olive groves, pine trees, and low Mediterranean vegetation. The island has no large settlement and is known mainly for its beaches, particularly Voutoumi and Vrika, where white sand or pale pebbles meet clear blue-green water.

Some of the most spectacular scenery is found on a trip to the San Juan Islands. No wonder. This 100-million-year-old mountain range turned archipelago, located a few miles northwest of Seattle, changes dramatically with the tide. There are 743 islands at low tide--and 428 at high tide.

Dorrigo National Park lies on the escarpment of northern New South Wales, about an hour from Coffs Harbour, where subtropical rainforest covers steep valleys and high country. The park forms part of the Gondwana Rainforests of Australia World Heritage Area, protecting plant communities that preserve links to ancient forests. Its elevated position creates broad views toward the Bellinger Valley and the coast, while dense forest keeps many walking tracks cool and shaded.
