Winiger Ridge at Gross Reservoir offers 30 dispersed camping sites along Forest Road 359, approximately 17 miles from Boulder. Sites accommodate both tent and RV camping, with clearance requirements varying by location. The area sits at 8,000 feet elevation, creating significant temperature drops at night even during summer months. Most sites require 4WD vehicles for access due to rough forest service roads, which often become impassable after rain or snow.
What to do
Trail access for non-equestrian hikers: The Forsythe Canyon Trail starts near the campground area and leads to the northwest side of the reservoir. "It is a great 1 mile loop that ends at the north west side of the lake. I took a hammock with me and planted myself on one side of the lake's perimeter, overlooking a nice section of the reservoir," notes Daniel B.
Paddling options: Water sports are popular at the reservoir despite restrictions. "Gross Reservoir is not gross! It is an awesome SUPing, kayaking, or canoeing option close to Denver and Boulder... There are a lot of inlets to paddle into and trails to explore," shares Karl G. Note that launching watercraft is only permitted at the designated boat launch on the southeast side, not from campsites.
Scenic driving routes: The Golden Gate Canyon State Park area provides road-based exploration opportunities within 30 minutes of Winiger Ridge. "The drive up can be a bit breathtaking, but it can be done!" according to Minette and Ron G., who found the natural beauty abundant in the surrounding region.
What campers like
Proximity to Boulder: Many campers value the accessibility of Winiger Ridge at Gross Reservoir given its location. "Stayed Sunday night and there is a Mine or Quarry on the other side of the 'lake'," reports melissa M. This mining operation creates a notable difference from more remote campgrounds despite the site being just outside Boulder.
Secluded campsites: The layout provides more privacy than many established campgrounds near the city. "All-wheel drive and higher clearance car helped getting in, as the road is pretty bumpy. Stayed in the last park-in campsite. Had to hike in to the lake, but was much easier than bringing in camping gear to the lake-side campsites," notes Dorothy.
Wildlife viewing: At Hermits Hollow Campground within day-trip distance, wildlife observation opportunities complement Winiger Ridge experiences. "Moose and black bear apparently frequent but haven't caused any problems. This is our 3rd stay here, and one of our favorites," reports Wade R. These wildlife viewing opportunities extend to the Winiger area.
What you should know
Strict regulations: The reservoir has enforced rules regarding recreation. "There are a lot of rules that are strictly enforced. There is no swimming in the reservoir... You can only launch your boat at the boat launch on the southeast side of the reservoir that is monitored by a ranger. He requires you to have a life vest, whistle, and your name written on your boat," explains Karl G.
Seasonal construction noise: Recent reservoir projects create periodic disruption. "There is a Mine or Quarry on the other side of the 'lake' and they worked non stop for 24 hours, which means non stop noise. Once it got dark they had 3 bright spot lights that traveled across and lit up most of the campsites so you can't see any stars," warns melissa M.
Trail conditions: Unlike the equestrian trails mentioned in the existing description, hiking paths have their own characteristics. At East Portal Campground, a visitor shared: "There is a trailhead near the front of the campground that leads to several trails. Very pretty place to stay." These trail conditions are typically less maintained than official park systems.
Tips for camping with families
Plan for minimal facilities: Unlike developed campgrounds, Winiger Ridge offers no permanent restroom facilities. "Primitive camping with one porta potty on the way in," notes Dorothy. Families should bring portable toilet facilities and waste disposal bags.
Safety considerations: Wildlife awareness is essential when camping with children. "Also there are mountain lions in the area so the national forest recommends not bringing your dogs which also isn't mentioned here at all," cautions melissa M., highlighting the need for proper food storage and wildlife precautions.
Alternative family-friendly options: For families seeking more amenities, Golden Gate Canyon State Park provides structured campground alternatives. "Our family loves this spot, the privacy and natural beauty all easily accessible for a 1 night trip for a family breaking in some unruly toddlers to the camping experience," shares andrew B.
Tips from RVers
Vehicle requirements: Access challenges extend beyond equestrian considerations. "Gnarly ass road, not for trailers/sedans... I wouldn't try this with a camper/RV, or anything that doesn't have high clearance and power," warns Graham S. Most RVs larger than 20 feet will struggle to access the majority of sites.
Site selection strategy: The first few sites offer better RV access. "Camp sites are nice, but except for a few (~5) the rest require a serious climb (drive) up a gnarly hill with deep ruts," continues Graham S., suggesting RV campers should arrive early to secure one of these limited suitable spots.
Water access limitations: No water hookups exist, and reaching the reservoir from campsites presents challenges. "You cannot access the lake from any campsite, it's a steep drop off from the area. So if you are looking to kayak or paddleboard, or camp lakeside this is not where you want to go," explains melissa M.
