Hubbard Park is a popular outdoor recreation destination. The park is crossed by a number of hiking trails, most notably the blue-blazed Metacomet Trail (maintained by the Connecticut Forest and Park Association), which traverses East Peak and West peak the park. Trails are open to hiking, backcountry skiing; roads are open to bicycling and mountain biking. Swimming and rock climbing are prohibited. From the top of Castle Craig it is possible to see most of the Quinnipiac Valley region, Long Island Sound, and the distant higher peaks of southern New England. East Peak is often cited as the highest mountain within of the coastline from Cadillac Mountain in Maine to Florida, however, nearby West Peak is higher.
