Hetch Hetchy Reservoir, Lake Vernon and Laurel Lake Loop

Nestled within the stunning landscapes of Yosemite National Park, the Hetch Hetchy Reservoir, Lake Vernon, and Laurel Lake Loop offers a challenging yet rewarding adventure for seasoned hikers. This 45 km (approximately 28 miles) loop trail boasts an elevation gain of around 1600 meters (about 5,250 feet), making it a demanding trek that promises breathtaking views and a deep connection with nature.

Getting There

The trailhead is conveniently located near Tuolumne County, California. For those traveling by car, you can reach the trailhead by taking Highway 120 to Evergreen Road, which leads directly to the Hetch Hetchy Entrance Station. From there, follow the signs to the O'Shaughnessy Dam, where the trail begins. If you prefer public transport, the Yosemite Area Regional Transportation System (YARTS) offers bus services to Yosemite National Park, though additional arrangements may be needed to reach the trailhead from the park's main areas.

Trail Highlights and Navigation

The loop begins at the O'Shaughnessy Dam, a significant landmark with historical importance. Constructed in the early 20th century, the dam was a controversial project that led to the flooding of the Hetch Hetchy Valley to provide water to San Francisco. As you start your journey, take a moment to appreciate the engineering marvel and the surrounding granite cliffs.

The trail initially follows the shoreline of the Hetch Hetchy Reservoir, offering stunning views of the water and the towering cliffs. As you progress, the path ascends through lush forests and meadows, providing opportunities to spot diverse wildlife, including black bears, mule deer, and a variety of bird species. Keep your eyes peeled for the vibrant wildflowers that dot the landscape, especially in the spring and early summer months.

Lake Vernon and Laurel Lake

Approximately 16 km (10 miles) into the hike, you'll reach Lake Vernon, a serene alpine lake surrounded by granite peaks. This is an ideal spot to rest and enjoy the tranquility of the wilderness. The trail then continues through dense forests and rocky terrain, leading you to Laurel Lake, another picturesque body of water nestled in the high country. Both lakes offer excellent opportunities for photography and reflection.

Navigation and Safety

Given the trail's difficulty, it's crucial to be well-prepared. Ensure you have a reliable navigation tool like HiiKER to track your progress and stay on course. The trail can be challenging to follow in certain sections, especially where it traverses rocky or densely wooded areas. Always carry a detailed map and compass as a backup.

Final Stretch

The loop eventually brings you back to the Hetch Hetchy Reservoir, completing the circuit. The descent offers sweeping views of the valley and the reservoir, providing a fitting end to this demanding yet unforgettable hike. Remember to pack out all trash and respect the natural environment to preserve the beauty of this remarkable trail for future adventurers.
