Walden Pond, in the north section of Lynn Woods, is Lynn Wood's largest reservoir, offering serene water views and wildlife. No swimming, fishing, or boating is permitted as this is a drinking water source for Lynn.

The Lynn Woods Reservation was founded in 1881, the second largest municipal park in the United States, is a 2,200-acre municipal forest park located in Lynn, Massachusetts. The Woods offers over 30 miles of scenic trails for hiking, running, horseback riding, mountain biking (not allowed during the winter), cross-country skiing, and nature walks. Three active reservoirs provide pretty pond-like scenery among natural forestland, as well as clean water for the City of Lynn. Dungeon Rock is a well-loved underground tunnel with a history of pirate lore and treasure seekers. The Rose Garden, Houghton Horticultural Garden, and Amphitheater areas provide more formal settings to explore.
