Half Dome Loop via Clouds Rest from Tenaya Lake

While the initial sections near Tenaya Lake might be jog-able, the overall route is extremely strenuous and challenging for continuous jogging. It involves significant elevation changes, technical terrain, and exposed sections like 'The Spine' on Clouds Rest, which are not suitable for running. This 37.6 km loop with 1817 m of elevation gain is considered a difficult hike, even for experienced trail runners, and many sections will require power hiking or walking.

The terrain varies significantly. You'll start with relatively flat sections through forests and meadows near Tenaya Lake before encountering steep ascents with switchbacks, especially on the approach to Clouds Rest. The path includes rolling granite formations and intricate old trail work. The final approach to Clouds Rest features 'The Spine,' a narrow granite ridge with steep drop-offs. If you continue to Half Dome Summit, expect further rigorous climbs, including the iconic Half Dome cables. Snow can also be a factor, particularly earlier in the season.

A permit is required to ascend the Half Dome cables. This is a highly competitive lottery system. While a permit is generally not needed for Clouds Rest itself, if your loop includes the Half Dome cables, you must secure a permit in advance. Always check the official Yosemite National Park website for the latest permit requirements.

Yes, Yosemite National Park charges an entrance fee per vehicle or per person. This fee grants you access to the park for a set number of days. You can purchase passes at the park entrance stations or online in advance. It's always a good idea to check the current fee schedule on the official NPS website before your visit.

This loop typically starts from the Tenaya Lake area. Parking is available near Tenaya Lake, but it can fill up quickly, especially during peak season. Arriving early in the morning is highly recommended to secure a spot. Always check for any specific parking regulations or restrictions in the area.

The best time to hike this loop is generally from late spring to early fall (typically June through October), after the snow has melted and before new snow arrives. Always check current trail conditions and weather forecasts, as snow can persist at higher elevations well into summer, and early season conditions can be challenging. The Half Dome cables are usually installed from late May/early June to mid-October.

This loop offers incredible scenery. From Clouds Rest, you'll get 360-degree panoramic views, often considered superior to those from Half Dome, including a unique perspective of Half Dome Summit itself, Tenaya Canyon, Tenaya Lake, and vast expanses of the Sierra Nevada. The trail also traverses beautiful forests and meadows, offering diverse natural beauty throughout.

No, dogs are generally not permitted on unpaved trails in Yosemite National Park, including this loop. While dogs are allowed on paved roads, in developed areas, and on some specific paved trails, they are restricted from wilderness trails to protect wildlife and natural resources. Always check Yosemite's official pet regulations before bringing your dog to the park.

Yes, the route utilizes significant portions of the Clouds Rest Trail (60%) and the Half Dome Trail (12%). It also passes through sections of the High Sierra Camp Loop (16%), the John Muir Trail (22%), and the Sunrise Lakes Trail (2%).

Clouds Rest is often highlighted for offering even better and more comprehensive views than Half Dome, including a spectacular vantage point of Half Dome Summit from above. It stands at a higher elevation (9,926 feet) than Half Dome and typically experiences fewer crowds. The narrow, exposed granite ridge known as 'The Spine' leading to its summit is a thrilling and unique feature.

Given the length and difficulty, you should pack plenty of water (at least 3-4 liters), high-energy snacks, a headlamp, a first-aid kit, sun protection (hat, sunscreen, sunglasses), layers of clothing for varying temperatures, and sturdy hiking boots. If you plan to ascend Half Dome, you'll also need gloves for the cables. Always carry a map and compass or a reliable GPS device, as cell service can be unreliable.

This is a very long and strenuous loop. While the tour data suggests a duration of approximately 6.5 hours for jogging, for most hikers, especially considering the technical terrain and significant elevation gain, it will take much longer. Plan for a full day, likely 10-14 hours, depending on your fitness level, pace, and time spent enjoying the views. Starting very early is crucial to ensure you finish before dark.
