Hidden hike in residential Clifton Park, formerly the "Round Lake Reservoir" The target of today's hike used to be known as the "Round Lake Reservoir" and was owned by the Round Lake Water Company. It's now a little-known Nature Preserve owned by the Town of Clifton Park. This spot has been an attractive place to explore for local residents for at least as long as the neighboring houses have been here, which is 1970. It's a short and pleasant hike, with the only known hazards being the legendary "North Woods Mosquitoes". They're small, but they can be numerous and VERY hungry!
