Garnet Trail

Explore the Garnet Trail

Garnet was named the Connecticut state mineral in 1977 by the General Assembly.  Our state is one of the finest sources of garnets in the world, found in several formations around the state.

The Garnet Trail was created by the state geologist in 2009 and updated in 2021.  While not a literal trail it is a series of notable locations where the state mineral (Almandine garnet) occurs along existing greenways, state parks/forests, and designated open space.

The state maintains a map of locations here:

Unfortunately, the accompanying guide to the Garnet Trail was lost when the state transitioned to their current online portal. The official guide has been updated by current state geologist Margaret Thomas in 2022.

Reminder: Please do not collect the minerals. Collecting minerals is prohibited on state land. These minerals are for all of the citizens of Connecticut to enjoy. Please be considerate of others and take nothing but photos.
