On the border region between Argentina and Chile is Volcan Lanin, a volcano that is wildly popular with hikers and rock climbers. The truly adventurous can seek permission at the Lanín national park office, show proof of supplies, and then trek to the summit on an often snow-capped route. Alternatively, a short walk of under an hour can take visitors to the Volcán Lanín’s Cara Norte, or north face, which also offers views of the lake called Lago Tromen and the surrounding forest.
