About Sunset-Union Valley
Overview
Sunset Campground is situated on the shores of Union Valley Reservoir, among the towering cedar and ponderosa pines of Eldorado National Forest. Aptly named, the campground is a fantastic destination for colorful sunset views over the lake. All water activities are popular here, but it's also fun to bring a bike and explore the neighboring bike trail.
Eldorado includes the famed gold mining territory of the 1800s. Remnants of the days of the California Gold Rush can be found all around the region.
Recreation
On the water, sailing, boating and swimming are very popular. For hikers and bikers, the Union Valley Bike Trail and Bassi Falls Hiking Trail are great for exploring. Fishing in the lake includes rainbow, brown, mackinaw trout and kokanee salmon.
The bike trail connects with the campground, near the boat ramp, and stretches for 4.8 miles along the eastern shores of the lake.
Facilities
The large campground has 121 single-unit sites including 30 tent-only spots. Amenities include a boat ramp with an accessible boarding dock, a paved parking area, dump station, vault toilets and drinking water. A swimming beach is also located onsite.
The First Come First Serve sites located at this campground remain listed as FF for the entire season. They will not show occupied/available as the status of these sites is ever changing. You must be on site at the campground to claim a FF site. No guarantees upon arrival that these FF sites will be avaiable.
Natural Features
Sunset Campground sits in the Crystal Basin at an elevation of 5,000 feet. Some sites are fully shaded while others sit in a meadow. The climate is similar to that of the Mediterranean with warm, dry summers and cold, wet winters.
Nearby Attractions

FAQ
How do I get a reservation at Sunset-Union Valley?
Campsite Sniper's current snapshot shows none of the 1,190 tracked site-nights open for online reservation at Sunset-Union Valley. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Sep 18, 2026 16:19 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
Which sites at Sunset-Union Valley fit a 35-foot RV?
17 of the 119 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 110 ft. 57 of those 119 sites have a recorded maximum length and 62 do not; they are not counted as fitting.
Does Sunset-Union Valley have online availability right now?
As of the Sep 18, 2026 snapshot, none of the 1,190 tracked site-nights are open for online reservation. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. A free Campsite Sniper alert tells you if any date opens online.
