Williams Lake is a serene alpine lake in Pitkin County, nestled in the mountains between Marble and Redstone along the Crystal River valley. This is the kind of place that inspired John Denver to write songs about Colorado. Surrounded by towering peaks and dense aspen groves, the lake sits at high elevation in a setting that feels genuinely remote despite being accessible by dirt road from the Crystal River valley floor.
Fishing and camping are the two main reasons visitors come to Williams Lake. The lake supports trout populations, and both shore fishing and fly fishing are productive, particularly in the early morning before wind picks up across the water. The shoreline offers multiple casting spots, and the calm surface on still mornings reflects the surrounding peaks in near-perfect detail. Bring your own gear, as there are no rental facilities anywhere nearby.
Camping at Williams Lake is rustic and dispersed. Sites are informal, spread around the lake among the trees with no hookups, no potable water, and no formal facilities beyond the natural setting. This is genuine backcountry-style camping reached by vehicle rather than a long hike, which makes it appealing to families and anglers who want a remote experience without a heavy pack. Campfires are permitted in existing fire rings when fire restrictions allow, but bring your own firewood.
The area is managed by the Bureau of Land Management, and some visitors have noted that maintenance has declined in recent years, with litter and wear visible around popular camping spots. Practice leave-no-trace principles and pack out all trash to help preserve this beautiful location for future visitors.
The drive to Williams Lake follows unpaved roads that require a vehicle with decent clearance. The final approach can be rough, with ruts and rocks that worsen after rain. There is no cell service in the area, so bring maps and arrive prepared with everything you need. The nearest town with services is Carbondale, roughly 30 to 40 minutes away depending on road conditions.
Williams Lake is best visited from late June through mid-October. Summer brings wildflowers and warm afternoons, while fall transforms the surrounding aspen forests into a sea of gold. The lake sits high enough that afternoon thunderstorms are a regular occurrence in July and August, so plan to set up camp and get off the water before early afternoon. For visitors seeking a peaceful mountain lake with honest fishing and camping far from crowds, Williams Lake rewards the drive.
