Callahan State Park is a 820-acre day use area located in Northwest Framingham. Callahan has seven miles of marked trails and is used for activities including fishing, hiking, horseback riding (horses not provided) and cross-country skiing. Within the park are nearly 100 acres of open fields, 70 acres of which are currently under an agricultural lease.
No trail maps were available at the North gate, and the signage was poor. There were many side trails and it was not always obvious which way to go. The EveryTrail GPS guide often had a problem getting readings. The dogs had a great time even though we never made it to the lake.
