Located in Greenville in Plumas County, Round Valley Lake Nature Trail offers a serene escape for outdoor enthusiasts and their dogs. The drive there is straightforward: head north on Highway 89 from Quincy, then turn left on Hideaway Road just before entering Greenville. After about three quarters of a mile on Hideaway Road, you’ll turn left onto Round Valley Road, which climbs up to the lake and the trailhead parking area.

The well-maintained path circles Round Valley Lake at a gentle pace, making it accessible whether you’re looking for a leisurely stroll or want to introduce your dog to hiking. The lake itself is the main attraction—the water reflects the surrounding forest and mountains, and the trail stays close enough that you get views throughout the walk. The terrain is easy underfoot, with no steep sections or technical footing to navigate, so you can focus on the scenery rather than watching your step constantly.

The area feels genuinely quiet, which makes it appealing if you want to avoid crowded trailheads. Your dog will appreciate the shade from the surrounding trees and the chance to explore at a natural pace. The proximity to the parking area means you’re never far from the car if you need to head back early, though most people find they want to complete the full loop.

The trail works well year-round, though spring and early summer offer the most pleasant weather. The U.S. Forest Service maintains this area, so you can check their official website for any current trail conditions or seasonal closures before you go. It’s worth noting that the road up to the trailhead can get rough in winter, so timing your visit for drier months makes the drive easier and more reliable.
