Mount Tom State Park is a public recreation area lying south of US Route 202 in the towns of Washington, Litchfield, and Morris, Connecticut.

[5] A condition of the Senff gift was that a permanent observation tower be maintained at the summit of Mount Tom.

The State Park Commission recommended that a stone tower be built to replace a wooden structure that had stood at the spot since 1888.

Visitors can climb to the top for views that extend to Mount Everett in Massachusetts, the Catskills in New York, and Long Island Sound.

[5] The park is notable for the presence of the metamorphic rocks gneiss and schist, the minerals quartz, garnet and hornblende, and boulders carried to the site by Ice Age glaciers.
