Beaver Brook offers 35 miles of well-maintained trails. Be sure to take a map! Well-behaved dogs are allowed on a leash.  Multi-purpose trails permit horseback riding, and mountain biking .


The Maple Hill gardens include 13 beautiful theme gardens, a Victorian gazebo, a wisteria arbor, 350 species of flowers and shrubs and a demonstration compost court.
