Panum Crater Rim Trail

The trail primarily consists of loose, pea-sized pumice gravel, which can feel like "squishy footing." The path leading up to the rim is described as "ashen slopes." While there are mellow inclines and declines, the loose nature of the pumice means stable footing and good ankle support are essential, especially for jogging. It's more like running on soft sand or gravel than a firm path.

While the full loop is about 4.5 kilometers (2.8 miles), jogging it can take around 30-40 minutes, depending on your pace and how often you stop to enjoy the views. Circumnavigating the crater can take up to an hour if you're walking or taking your time.

From the Rim Trail around Panum Crater, you'll get stunning panoramic views. Look north to Mono Lake, west to the majestic Sierra Nevada mountain range, and across vast sagebrush plains. You can spot landmarks like Negit and Paoha Island, Black Point, and the South Tufas. The volcanic landscape itself, with formations of obsidian, pumice, and rhyolite, creates an "otherworldly" environment.

The trail is generally rated easy to medium difficulty. While the distance and elevation gain are modest, the loose pumice surface presents a moderate challenge for jogging. Beginners should be prepared for the "squishy footing" and ensure they have appropriate footwear for stability. It's a good option for those looking for a unique, slightly challenging soft-surface run.

The trail is completely exposed, so spring and fall offer cooler temperatures and more comfortable conditions for jogging. Summer can be very hot and windy, making an early morning or late afternoon visit preferable. Always carry water, regardless of the season.

Yes, dogs are generally allowed on the trail. However, as part of the Inyo National Forest, it's crucial to keep your dog on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Remember to pack out any waste.

No, there are no specific permits or entrance fees required to access the Panum Crater Rim Trail itself. It is part of the Inyo National Forest, which generally does not charge an entrance fee for day use. However, always check for any updated regulations or fire restrictions before your visit.

The trailhead for the Panum Crater Rim Trail is easily accessible. There is a dedicated parking area at the base of Panum Crater, which serves as the starting point for the loop. The trail is well-marked from the parking lot.

Yes, while you'll primarily be on the Panum Crater Rim Trail, the route also passes through sections of the Panum Crater Plug Trail, Panum Crater Road, and Panum Crater West Road. The Panum Crater Plug Trail, which ventures into the crater's interior, is significantly more challenging with volcanic boulders and rubble, and not suitable for jogging.

Panum Crater is a perfect example of a rhyolitic plug-dome volcano, formed relatively recently about 650 to 680 years ago, making it part of the youngest mountain range in North America. Its formation involved an outer pumice rim and an inner jagged core of obsidian and pumice. The area is part of the geologically active Mono Craters, which are dormant but not extinct. Visitors are prohibited from collecting obsidian or any other rocks.

Given the exposed nature of the trail and potential for high winds, it's essential to bring plenty of water, especially on warmer days. Good quality trail running shoes with ankle support are highly recommended due to the loose pumice. Sun protection like a hat, sunglasses, and sunscreen is also advisable.
