difficult Difficulty

The High Sierra Circle presents a challenging yet breathtaking backpacking loop through Kings Canyon, offering sweeping alpine views, rugged climbs, and serene forest trails. This guide covers essential preparations and what to expect, helping adventurers gear up for a memorable Sierra experience.

Adventure Tips

Hydration is Non-Negotiable

Water sources are frequent but require reliable filtration or purification to stay safe. Carry enough water between sources, especially at higher elevations where vegetation thins.

Wear Durable, Supportive Footwear

Expect rocky, uneven terrain. Sturdy hiking boots with ankle support reduce injury risk and improve stability on steep ascents and descents.

Start Early Each Day

Mountain weather can turn fast—early starts also allow you to cover more ground during cooler temperatures and avoid afternoon storms.

Pack Layers for Rapid Weather Changes

Temperature swings are common; lightweight insulating layers combined with waterproof shells prepare you for rain, wind, and cold nights.

The High Sierra Circle: A Backpacker's Ultimate Route Through Kings Canyon

The High Sierra Circle weaves a demanding yet rewarding trail through some of Kings Canyon’s most stunning and diverse landscapes. Spanning roughly 70 miles, this backpacking loop challenges hikers with an elevation gain topping 15,000 feet across rugged granite passes and lush forested valleys. The trail captures the raw personality of the Sierra—rivers that dare you to keep pace, cliffs that stand fiercely in your path, and alpine meadows waving in slow breezes inviting moments of calm.

Starting near Road’s End in Kings Canyon National Park, hikers ascend gradually into a world carved by ancient glaciers and lightning storms. The terrain shifts unpredictably—boulder fields give way to pine-shaded paths where sunlight filters in restless beams. Crossing pivotal landmarks like Bishop Pass, the trail tests endurance with demanding climbs, while rewarding vistas open expansive views of towering peaks and shimmering lakes.

Be prepared for intense variations in temperature and weather, as the High Sierra’s atmosphere is a force unto itself—quick to shift and unapologetically exacting. Adequate hydration is essential; streams and lakes beckon but must be treated or purified. Solid, broken-in boots with firm ankle support are a necessity for negotiating rocky terrain, while layered clothing will help you respond to rapid weather changes.

Timing your journey between July and September offers the most reliable trail conditions, after late spring’s runoff subsides but before early season snow returns. Being an expert navigator benefits anyone tackling this route, as trail markers can fade and the wilderness remains fiercely independent of human convenience.

Camping spots abound but come with strict regulations to protect the fragile wildlands. Take only memories and leave no trace.

For the backpacker seeking an immersive taste of the Sierra’s wild edge—one that balances grit with grandeur—the High Sierra Circle through Kings Canyon delivers an adventure both practical in its demands and rich in natural rewards.
