Camping at Union Reservoir has been discontinued since 2018, when the municipal facility converted former campsites into additional day-use parking and recreation areas. The reservoir sits adjacent to Longmont and previously offered tent camping with fire pits on Friday and Saturday nights only. Sites were located next to a dirt access road and large paved parking lot.
Past campers noted the proximity to water activities and boat rentals, though tent spaces lacked privacy due to their placement near vehicle traffic areas. The city plans future development of a modern campground with full hookups and amenities, but no timeline has been established. Campers can find places to camp near Longmont at nearby private facilities like G & T Farms while enjoying day use of the reservoir's swimming and paddling opportunities.
