Guided Hike of Bunsen Peak

Guided Hike of Bunsen Peak

Overview
Named for Robert Bunsen, the inventor of the Bunsen burner and early supporter of Yellowstone’s geothermal studies, this moderately strenuous hike offers a powerful mix of scenery, science, and sweat. You’ll ascend through areas shaped by the historic 1988 Yellowstone wildfire, gaining insight into how fire reshapes an ecosystem while hiking through a landscape rich in geologic and botanical diversity.

Along the way, we’ll pass towering volcanic pinnacles and budding wildflowers and look for elk, marmots, and raptors. Your guide will highlight Bunsen Peak’s unique volcanic history and the stories behind Yellowstone’s ever-changing terrain.

Route Details
The trail begins a few miles south of Mammoth Hot Springs and Fort Yellowstone, ascending via well-maintained switchbacks through a regenerating forest. Bunsen Peak itself is the eroded core of an ancient volcano, offering sweeping views as you gain elevation.

At the 8,527-foot summit, you’ll feel the air thin and the breeze pick up—but the 360-degree panoramic views of Electric Peak, the Gallatin and Washburn Mountains, and the Mammoth Hot Springs basin will more than reward your effort. We’ll take time at the top to enjoy a picnic lunch, take photos, and savor the scenery before descending the same trail.
