What to expect on Green River loop from Upper Green River Lake

As you traverse this route, you'll be treated to continuous, dramatic views of Squaretop Mountain, a granite monolith that dominates the landscape. The trail skirts the pristine Green River and its lakes, winding through varied terrain from sage-covered slopes to spruce-pine forests. Expect sections of exposed trail and gentle ups and downs, but the overall difficulty comes from the length and potentially rugged sections beyond the main Highline Trail. This route is best for hikers comfortable with longer distances and some navigational challenge, especially if venturing off the most established paths.

Planning your visit

Access to the Green River Lakes area is typically via the Highline Trailhead. While a short loop directly around Upper Green River Lake isn't a standard, well-marked path, this route likely incorporates sections of the Highline Trail, offering stunning views. Be prepared for potential navigation challenges and carry bear spray, as this is grizzly bear habitat. Mosquitos can also be relentless, so pack bug spray. The best time to hike is generally late summer once snow has melted and before early autumn weather sets in.
