Ushuaia is the hub for finding tours heading to the region's most popular spots, as well as its most hidden treasures. In summer, agencies concentrate on taking visitors out to remote estancias, fishing expeditions and multi-day treks. Come winter, operators arrange skiing, dog sledding and other winter snow adventures. Ushuaia is also from that most-southern city travelers should arrange for cruises to the last great frontier, Antarctica.
Tolhuin also has some local guides. Most specialize in fishing excursions. Others arrange boat trips across Lago Fagnano, a backdoor way to Ushuaia, and trekking excursions. Although RÃo Grande has many travel agencies, none do tours to local attractions. A few companies can book visits and stays at regional estancias.
