Come Walk the Newly Restored Trails at the Woodfield Reservation

Saturday, October 15th, 10 a.m. to 12 p.m.
Free Guided Walks & Refreshments

The Princeton Environmental Commission and Friends of Princeton Open Space invite you to celebrate the major trail improvements that have been made in this 100+ acre preserve over the summer. Meet at 10 a.m. on Saturday, October 15th at the park entrance on the Old Great Road for guided walks and refreshments.

Join us to walk the ¾ mile Scout Loop or walk a longer 2 1/2 mile loop to visit Tent Rock and Council Rock.

The trails have been cleared and clearly marked and boardwalk has been installed over spots that get muddy when it rains. The work was done by 18 volunteers organized by Friends of Princeton Open Space who spent 317 labor hours in 22 workdays clearing 1.5 miles of trail, constructing 1,000 feet of new trail and installing 220 linear feet of boardwalk.

This trail renovation was made possible by a $1,500 Open Space Stewardship Grant from the Association of New Jersey Environmental Commissions supplemented by $500 each from Friends of Princeton Open Space and the Princeton Environmental Commission. Support was also provided by Hamilton Building Supply Company.

Please wear shoes appropriate for hiking as the trails run through the woods and cover uneven terrain and bring a water bottle. Free. RSVP at Eventbrite.
