The bus slips out of Puerto Varas before dawn and the town’s color drains as the volcano grows in the windshield—a broad cone sharpening into a snowcap, a mountain that seems to change its mood with every cloud. By the time the trailhead at La Picada opens under your boots, you’re already in a different pace: a volcanic foothill where pebble and pumice crunch, and native lenga and coihue press close enough to catch your breath.
