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 LakeApproximately 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 SafetyGiven 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 StretchThe loop eventually brings you back to the Hetch Hetchy Reservoir, completing the circuit.
