This national park is the major tourist attraction in the region. It covers 180,000 hectares on the Seno de Ultima Esperanza. The Park is located 150 kms. from Puerto Natales and 400 kms. from Punta Arenas.

There are many hiking paths that cross widely differing types of terrain, such as pampas and thick Magellanic forests, and run along lakes with huge glaciers and icebergs. The park is surrounded by huge, craggy mountains, including the famous Cuernos del Paine (Paine Horns).

One of the most interesting excursions is to walk along LAGO GREY to the GLACIAR GREY. Along the way huge icebergs that have broken off of the glacier can be seen floating in the lake, pushed by the wind. The area of the park can be reached by a road on the south side of . This road leads to the (Bull Mountains), where there is a good view of the Paine Massif, Monte Balmaceda and the lakes, rivers and plains spread out below. There are cabins and campsites in this area of the park.

Among other routes that can be taken is the road to LAGUNA AMARGA (Bitter Lake) and , which follows a mountainous area peppered with little lakes that runs between NORDENSKJOLD to the north to the Sarmiento to the south.

It is possible to hike to LAGO PAINE and to continue into the wide valley that ends with GLACIAR DICKSON. From this glacier the northerly slopes of the Paine chain can be seen. One of these peaks is topped by a black, carggy rock in the shape of a Tehuelche Indian face. The facial profile can be made out, complete with the traditional headband that the Tehuelches wear for restraining their horses. The headband is decorated with snowdrifts even in summer.

There are many other hikes in the park, with the most famous being the weeklong circuit around the Paine Massif. On this circuit it is necessary to camp or stay in the various refugios (shelters) along the way.

Pumas, guanacos, foxes, hares, woodpeckers, condors and native birds such as the aguilucho and the rare martin pescador abound in the park.
