Timber Gap, Big Five-Little Five Lakes, and Monarch Lakes Loop

This is a challenging multi-day backpacking route. Most hikers plan for 3 to 5 days to complete the entire loop, depending on their pace and desired camping locations.

The loop is rated as difficult to extreme due to its significant length and substantial elevation changes, with an overall gain/loss of around 10,000 feet. Hikers will encounter intense climbs, such as gaining 3,000 feet in 3 miles to Black Rock Pass, and navigating steep, rocky descents. Unpredictable high-alpine weather and diverse terrain also add to the difficulty.

You'll traverse a diverse range of terrain, from steep, brush-covered hillsides and red fir forests to open slopes with numerous switchbacks and rocky outcroppings. Expect meadows, sections that are avalanche-scoured, and creek crossings. Earlier in the season, snowpack can be present at higher elevations and passes, and the footing can be loose in parts.

The loop offers breathtaking panoramic views. Highlights include vistas of the Mineral King Valley, the East Fork Kaweah River Valley, and prominent peaks like Vandever Mountain. From Timber Gap, you can see towards Alta Peak. The trail leads to stunning alpine lakes such as the Big Five Lakes, Little Five Lakes, Columbine Lake, and Monarch Lake, often nestled beneath peaks like Sawtooth Peak. From Blackrock Pass, you'll be treated to views of Mount Whitney and the wider Sierra Range.

The ideal time to hike this high-alpine loop is typically from late summer to early fall. Early summer can bring significant mosquito activity and lingering snowpack at higher elevations and passes, potentially requiring specialized gear like ice axes and crampons. Always be prepared for unpredictable weather, including cold nights, hail, and snow, even outside of winter months.
