Union is a wakeless lake, providing a perfect spot for sail boats, canoes, wind surfers and paddle boats to glide across the water without concerns about loud motors and disruptive waves. On the sandy beaches (yes, there really is sand!) families frolic and swim while friendly, well-behaved dogs can splash happily nearby in a designated off-leash area (note: the dog beach is not fenced in). There are also campgrounds, a playground, grills, a volleyball court and more.
Union reservoir is also home to the Union Sailing Club, an active sailing club with weekly races, and the Longmont Sculling Club which caters to both new and experienced scullers.
