Jumbo Mine Trail

The Jumbo Mine Trail typically starts from the historic Kennecott Mill Town area within Wrangell-St. Elias National Park & Preserve. Parking is available in McCarthy, and visitors usually take a shuttle across the Kennicott River to reach the Kennecott area, which serves as the trailhead for many hikes, including this one. For detailed information on access and shuttles, it's best to check the official NPS website.

The best time to hike the Jumbo Mine Trail is generally during the summer months, from late June through early September, when the snow has melted and the weather is most favorable. Wildflowers are also plentiful during this season. Early summer might present challenges with higher water levels in Bonanza Creek, potentially leading to wet feet.

While Wrangell-St. Elias National Park & Preserve generally allows pets, specific regulations apply, especially in developed areas and on trails. It's crucial to check the current pet policies on the official NPS website. If dogs are permitted, they must always be on a leash to protect wildlife and ensure the safety of other hikers.

The terrain on the Jumbo Mine Trail is varied and challenging. It begins on a relatively well-maintained path, sharing a section with the Bonanza Mine route. As you ascend, it becomes rockier and sandier, eventually leading to a scree slope where the trail fades out in the last half-mile. Hikers will encounter loose rock, may need to cross Bonanza Creek, and will traverse diverse Alaskan terrain, including a rock glacier.

Hikers are rewarded with magnificent views of the Kennicott Valley, the Chugach Range, and the Kennicott and Root Glaciers. You'll get stunning alpine vistas, including close-up views of Castle Mountain. The trail also leads to the historical remnants of the Jumbo Mine site and artifacts, offering a glimpse into early 20th-century copper mining operations. You'll also pass by the historic Kennecott Mill Town and a View of Kennicott Glacier from Kennicott Mine.
