Roosevelt National Forest's western edge holds Winiger Ridge at Gross Reservoir, a free, first-come-first-served campground on Forest Road 359 that sits above Gross Reservoir outside Boulder. No reservations, no hookups, no toilets within the camping area itself. The road in is the first thing to understand: deep ruts, steep grades, and sections that have left low-clearance vehicles stuck. Kerrigan T. puts it plainly: "Not a good road for a trailer." High-clearance trucks and Jeeps handle it best, though a capable AWD vehicle can reach the first few sites. A schematic map near the entrance marks the designated plots, and that map is the last bathroom you'll see before reaching camp.
The campground has roughly six drive-in sites, a handful of walk-in tent sites near the parking area, and additional spots down by the water, about a half-mile hike from the lot. Sites are spacious enough for multiple tents and a couple of vehicles, each with a fire pit and picnic table. The walk-in area near the parking lot has reservoir views, but campers there should know the water treatment facility's lights run through the night and shine into that zone. There is also active construction or mining across the reservoir that, depending on the season and day, can generate noise and bright spotlights well after dark.
Gross Reservoir is the main draw. Paddleboarding, kayaking, and canoeing are common, though the reservoir serves as Denver's drinking water, so swimming is prohibited and rangers actively enforce that rule. Boats must launch from the southeast side, and each person needs a life jacket on board. Daniel B. notes, "Bring in your own water as well," since there is no potable water within the campground. The Forsythe Canyon Trail, a moderate one-mile loop, leaves from the parking area and reaches the northwest shore.
Proximity to Boulder means sites fill fast on Friday evenings, and late arrivals in peak season often find nothing open. Camping outside designated spots carries a minimum fine. November visits, by contrast, tend to be quiet, with far fewer campers willing to deal with the cold. Mountain lion activity has been noted in the area, which is worth factoring in for anyone bringing dogs. Nearby, Gross Reservoir Dispersed provides an alternative for those who find Winiger Ridge full, and campers planning a longer stay in the region can explore places to camp near Eldorado Springs for additional options.
Come with a full water supply, a plan for waste, and realistic expectations about the road conditions, and Winiger Ridge gives campers direct access to one of the more accessible reservoirs along the Front Range.
