Snoqualmie Valley Trail
The Snoqualmie Valley Trail is one of the longest rail-trails in Washington State and passes through some of the most beautiful countryside in the Puget Sound region. The trail surface is mostly gravel and dirt, with some paved sections near towns. It passes through the towns of Carnation and Snoqualmie, where you can stop for food and water. The trail's south end at Rattlesnake Lake is a stunning destination, with the lake, surrounding mountains, and the Snoqualmie River. The trail is part of the regional Mountains to Sound Greenway trail network.

Early Morning (7–10 AM)
The best time to ride in Aspen. Trails are fresh, temperatures are cooler at altitude, and you'll beat the afternoon crowds on popular routes like Maroon Bells.
Late Morning (10 AM–Noon)
Great for longer rides when fully acclimatized. Aim to be off exposed ridgelines by early afternoon as afternoon thunderstorms are common in summer.
Avoid Afternoons in Summer
Aspen summers bring rapid afternoon thunderstorms, especially above treeline. Start early and plan to return before 2–3 PM. Always bring a rain layer.
A gravel bike or mountain bike is ideal for the Snoqualmie Valley Trail. The surface is mostly gravel and dirt, so road bikes with thin tires will struggle. Bring water and food—there are services in Carnation and Snoqualmie but long stretches between towns. The trail is mostly exposed in farmland sections, so bring sun protection in summer and rain gear in winter.
- •Wear a helmet: Always wear a properly fitted mountain bike helmet — Aspen trails are technical
- •Acclimatize first: Aspen sits at 8,000 ft — give yourself 1-2 days to acclimatize before hard rides, especially if flying in
- •Watch for thunderstorms: Afternoon summer storms build fast in the Rockies — start early and be off exposed terrain by 2 PM
- •Bring water & snacks: High altitude increases dehydration. Bring more water than you think you need plus energy snacks
- •Know wildlife etiquette: Aspen has bears, moose, and elk. Make noise on blind corners and know how to react to wildlife
