Hydrate Before and During the Hike

Water sources can be sparse and unpredictable; bring at least 2 liters of water and consider a portable filter if you plan to refill from streams.

Temperatures can shift rapidly. Carry moisture-wicking base layers and a waterproof jacket to adapt to sun, wind, or rain.

North Fork Trail to Lost Twin Lakes: An Essential Adventure in the Bighorn Mountains

The North Fork Trail to Lost Twin Lakes offers a rewarding journey deep into Wyoming’s Bighorn Mountains, where the landscape demands respect and rewards careful exploration. Spanning roughly 8 miles round trip with an elevation gain near 1,200 feet, this trail threads through dense stands of spruce and fir, their tall trunks whispering with the wind as you press onward. The path challenges your stamina yet unfolds with steady climbs rather than steep scrambles, making it accessible for hikers with some experience.

From trailhead to twin sapphire lakes, the route engages you with a varied terrain of mixed soft earth, rocky patches, and occasional creek crossings. Pushed onward by the current of the nearby North Fork Creek, the environment feels fiercely alive. The forest floor cushions your steps, while glimpses of snow-capped peaks appear as windows through the trees.

Planning your timing is critical. Early morning starts can catch the mountain in cool, muted light before the sun burns through the forest canopy. Pack enough water to keep ahead of thirst — the effort is steady, and streams at the higher elevations can be unreliable. Bring sturdy boots to handle the often uneven, root-speckled soil and protect your ankles on the rocky stretches.

Arriving at Lost Twin Lakes, you’ll find your effort rewarded with clear, cold waters reflecting the surrounding cliffs and evergreens. These lakes seem to sit quietly, daring you to pause and absorb their calm under the watchful eyes of circling raptors. It’s a place for reflection but also for practical safety — remember to pack out all trash and leave no trace, preserving the lake’s natural edge.

The North Fork Trail doesn’t simply offer a walk; it invites you into a dynamic exchange with a wilderness both generous and exacting. It asks for preparation, respect, and a readiness to move mindfully through terrain that is unfalteringly itself. Whether you come seeking quiet lakeside moments or a vigorous mountain trek, this trail stands as a compelling encounter with the Bighorn’s rugged heart.
