Summit Mount Hoffman & Swim in May Lake

Climb to Yosemite’s iconic Mount Hoffman with expert guides from The Lamplighters Adventuring Society and cool off with a swim in May Lake. A private, moderately challenging trip that reveals Yosemite’s backcountry beauty beyond the crowds.

Set in the heart of Yosemite National Park, California, The Lamplighters Adventuring Society LLC offers a standout private guided hike that leads adventure seekers beyond the usual crowds to the summit of Mount Hoffman. At 10,850 feet, this peak is widely regarded as one of Yosemite’s premier viewpoints, granting an unrivaled, sweeping panorama of the park's vast granite cliffs, alpine meadows, and shimmering river valleys. The journey begins at the May Lake Trailhead, where the trail threads through forests of towering Jeffrey pines and scattered rock outcrops, hinting at the granite that dominates Yosemite’s dramatic landscape.

What makes this trip exceptional is the balance of effort and reward: a moderately strenuous 5.5-mile round trip that includes a thrilling scramble near the summit. The guide’s expertise ensures safe navigation through rocky terrain, while providing insight into Yosemite’s unique ecosystems—like the subalpine flora clinging to life at high elevation. Upon reaching the summit, you’ll feast on a carefully prepared picnic lunch while absorbing unparalleled views that stretch across the High Sierra, including sights of Half Dome and Clouds Rest.

The adventure doesn’t end at altitude. On the descent, you’ll refresh with a swim in May Lake’s crystal-clear waters, a serene alpine basin surrounded by granite cliffs, perfectly cool after the exertion. This quiet backcountry experience is especially prized for steering visitors away from crowded valley floors into Yosemite’s tranquil, lesser-known wilds.

Lamplighters Adventuring Society’s tours blend local wilderness expertise with personalized service, making this hike a rare chance to connect deeply with Yosemite’s natural grandeur. For anyone seeking a rewarding day of hiking, scrambling, and swimming framed by some of California’s most iconic landscapes, this excursion delivers an accessible yet exhilarating outdoor experience designed for memory-making and breathtaking vistas.
