Don’t let the name turn you away. Gross Reservoir camping offers an amazing getaway, just outside Boulder, Colorado.
However, if you want a place with lots of amenities, look elsewhere. On the other hand, for unspoiled natural beauty in the heart of the Colorado Rockies, head toward Gross Reservoir. It’s a lesser-known area for recreational activities like hiking, camping, fishing, and certain kinds of boating.
About Gross Reservoir
Like many of our great modern lakes in the United States, Gross Reservoir manages water for the surrounding areas. Specifically, they designed and engineered it to handle the massive runoff from the Rocky Mountains to the west. Dwight Gross headed up the project, and the high mountain lake carries his name.
Abundant recreation opportunities followed after its completion in 1954. Many people enjoy hiking, camping, fishing, and rock climbing. Sorry, they don’t allow swimming or wading in the reservoir, but you can in nearby streams.
Gross Reservoir, 7,282 feet above sea level, sits in the Roosevelt National Forest and is owned and operated by Denver Water. Water pumps into this 440-acre lake through a structure called the Moffat Tunnel. The reservoir’s 340-foot concrete dam is being expanded to 471 feet (from the stream floor). Gross Reservoir will hold an estimated 25 billion gallons of water after construction.
When Is the Best Time to Visit?
Unless you like skating or ice fishing, summer is the best time to visit. Even during the hottest months of the year, it can get very cool at night. The water itself stays extremely cold year-round.
Because of Gross Reservoir’s proximity to the continental divide, you can have extreme and unpredictable weather. Dangerously high winds can pop up with little or no warning. For this reason, keep an eye on weather forecasts when Gross Reservoir camping.

Things to do at Gross Reservoir
Other than Gross Reservoir camping, you have many other recreation opportunities along its shore. Here are some of the most popular ones.
You can use non-motorized boats that you don’t need a trailer for at Gross Reservoir from May to September. This means “car-top” watercraft like smaller rowboats, canoes, kayaks, and inflatables.
The state regularly stocks the reservoir with several kinds of fish. They include three types of trout (rainbow, brown, and lake) and splake and kokanee salmon — also called silver trout, a close relative to sockeye salmon.
Many people love hiking the Forsythe Trail, which leads to a small waterfall. You can locate the trailhead on the National Forest Service System Road 359. The 3.2-mile trail (out and back) follows Forsythe Creek through a wooded area to a rocky canyon. You can even take kids on this easy hike. However, you might need a four-wheel-drive vehicle to get there on the rough road.
There are lots of reasons they call the place Boulder, even though it’s actually closer to the town of Nederland. You can find many irresistible rock formations here, perfect for climbing. You can try your luck with bouldering near the lake’s eastern shore.
