Backpacking the John Muir Trail (Starting Here) in Happy Isles, Yosemite Valley

Backpacking the John Muir Trail (Starting Here) in Happy Isles, Yosemite Valley

Introductory Overview

Happy Isles in Yosemite Valley marks the official start of the iconic John Muir Trail (JMT)—a 211-mile journey through some of the most stunning landscapes in the Sierra Nevada. Beginning here provides a memorable prelude to this epic trail, as you'll embark near the Merced River and pass through awe-inspiring granite cliffs that Yosemite Valley is famous for. Backpacking the JMT from Happy Isles is a unique experience because it combines convenience (proximity to Yosemite Village) with the challenge of ascending over 6,000 feet to the summit of Cloud’s Rest or Half Dome in the early stages. With permits required and logistics to plan, this guide provides essential details to get you started on the right foot.

Adventure Guide to Backpacking the John Muir Trail (Starting Here)

• Happy Isles Trailhead and Vernal Falls Footbridge:
  Starting at Happy Isles Trailhead, hikers ascend the Mist Trail toward Vernal Fall. This section offers breathtaking views, providing an invigorating start to your JMT journey. The rushing Vernal Fall is particularly stunning in late spring and early summer when snowmelt is at its peak. Plan for significant foot traffic here, so begin your hike early to avoid crowds.

• Little Yosemite Valley (First Camp Area):
  Approximately 4.3 miles from Happy Isles, this is a popular first-night camping spot. The designated backpackers’ camp offers amenities such as bear-proof lockers for food storage and nearby access to the Merced River for water (apply filtration). The designated camping zones also help preserve the wilderness while providing a safe and comfortable resting point.

• Nevada Fall and Clark Point Detour:
  Before reaching Little Yosemite Valley, the junction near Clark Point allows for loop options via the Mist Trail or the John Muir Trail proper. Take time to stop at Nevada Fall, which provides panoramic views from its 594-foot drop. The smooth granite landscape here is both dramatic and a preview of the terrain you’ll encounter later on the trail.
