Puerto Williams is a small Chilean city on Navarino Island, south of the Beagle Channel, and it calls itself the world's southernmost city, though nearby Ushuaia also claims that title. Surrounded by dramatic, snow-dusted mountains and the Dientes de Navarino, it was originally home to the Yaghan people. Founded as a naval base in 1953, it now serves Antarctic travel and offers a quiet, village-like alternative to bustling Ushuaia.

Ushuaia, the "End of the World," sits on the Beagle Channel beneath the Martial Mountains. A lively but remote resort, it's the last taste of city life before Antarctica or the wilds of Tierra del Fuego. Nearby, National Park Tierra del Fuego offers dramatic peaks, glaciers, fjords, and wildlife like penguins and whales, with excellent hiking and views. Local food features king crab, fresh sea bass, and cholgas (mussels).

Punta Arenas, Chile's "City at the End of the World," is a windy, remote but surprisingly cosmopolitan gateway to Antarctica. Built around Plaza de Armas, it offers views from Cerro de la Cruz, customs-free shopping, and history tied to Scott and Shackleton. It's also a base for Antarctic research, with nearby highlights including Torres del Paine, Alberto de Agostini, and penguin-filled Magdalena Island.

Set amid the raw, untamed beauty of Chilean Patagonia, Aguila Glacier offers a spellbinding encounter with towering ice, mirror-like waters and forested mountains. As your ship glides through this remote wilderness, keep watch for dramatic ice formations, soaring birdlife and the hushed, elemental atmosphere that makes this corner of South America so unforgettable.

Tortel is a commune in Southern Patagonia, Chile, known for its rugged wilderness, islands, channels, and striking wooden walkways that connect piers and houses above the vegetation, earning it the nickname "footbridge city." It is the sixth largest commune in Chile yet has only about 531 residents. The area was once inhabited by the nomadic Kawesqar; the town was definitively founded in 1955 and declared a Picturesque Zone of National Heritage in 2001.

Puerto Cisnes offers a glimpse of Chile's wild southern coast, where sheltered waters, forested hills and snow-dusted peaks create a dramatic Patagonian setting. This small port town is a gateway to the pristine landscapes of the Aysén region, with chances to enjoy fresh seafood, local hospitality and the untamed beauty of fjords, islands and abundant wildlife.

Windy Puerto Montt was long the end of the line in the Lake District; today the Carretera Austral continues south, but it remains the region's last major outpost and a hub for fishing, textiles, and tourism. The fast-growing city center has malls, condos, and offices, while the rest is mostly low clapboard houses above the Seno de Reloncaví. On sunny days, visit Playa Pelluco or other beaches, or drive the shoreline for views of the hills.

Valparaiso has long inspired writers, poets, musicians and artists. Though a bit rough, its bohemian charm, street art, nightlife, live music, colorful clifftop homes and striking architecture make it one of Chile's most beloved cities. Founded in 1536 by Juan de Saavedra, it still has colonial buildings despite fires and earthquakes. Nearby are Pablo Neruda's ship-shaped house and the Casablanca Valley vineyards, while Chile's wine culture also gave rise to pisco.
