The Great Idaho Bikepacking Loop: Gravel Roads, Rugged Mountains, and Zero Cell Service

The Great Idaho Bikepacking Loop stretches nearly 700 miles through Idaho’s wild heart, challenging riders with a mix of gravel roads, steep mountain passes, and stretches where the silence is broken only by the churn of your tires on dirt. This route refuses to be tamed; it demands respect and readiness. If you’re chasing solitude far from cell signals, and an experience where nature dares you to keep moving forward, this is it.

Starting near the small town of McCall, the loop weaves through thick forests where pine trees lean over the trail like old friends watching your progress. Rivers cut across your path, pushing cool currents that invite you to pause, unwind, and refill. Elevation gains are relentless—expect to climb over 40,000 feet total, with technical sections that test your bike-handling skills on rocky, uneven gravel. Days can stretch to 60 or 70 miles between resupply points. Hydration and nutrition planning aren’t a luxury but a necessity.

Practical planning is as critical as the thrill of discovery. Pack lightweight, durable gear and bring reliable navigation tools since GPS signals can falter here. Cold mornings in the mountains shift swiftly to warmer afternoons, so layering is key. Footwear with solid tread is a must to handle varied terrain that ranges from smooth gravel paths to loose scree on long descents.

This loop moves through mountains fiercely protective of their silence. Wildlife like elk and black bears may cross your path without ceremony, reminding you that you’re a visitor. Camping spots offer dome-shaped clearings framed by towering idol-like trees—perfect for catching stars that scatter across the vast night sky.

Timing your ride between late June and early September maximizes good weather and minimizes snow hazards, but be prepared for sudden storms that can sweep through like a test. Cell service is near nonexistent; let that sink in. Each mile is an engagement with a landscape fiercely itself, offering challenge and reward to those who answer its call.

If you seek a trip defined by solitude, strenuous climbs, and wide-open spaces, the Great Idaho Bikepacking Loop delivers all that—and more. Bring your grit, your curiosity, and a readiness to embrace the unexpected. Here, adventure is not just in the miles but in the moments of silence and sweat, when the mountains seem to speak and you listen.
