Historic city-owned park overlooking Watertown from atop a hill with multiple access points. The park was designed by Frederick Law Olmstead, the architect who designed Central Park in New York City. Thompson Park has acres of picnic and open space, is home to the New York State Zoo at Thompson Park, an 18-hole golf course, playground, stone stairways and pavilions, tennis courts, walking and cycling trails and an outdoor skating area. Picnic areas can be reserved for gatherings. The park contains the Thompson Park Vortex, a constantly relocating location said to mysteriously teleport visitors to other areas of the park without explanation; a favorite among spooky enthusiasts. The park is open 7 a.m.-9 p.m., year-round.
