Frost Woods Loop is a 2.5 mile lightly trafficked loop trail located near Spotswood, NJ that offers the chance to see wildlife and is rated as moderate. The trail is primarily used for hiking and mountain biking and is accessible year-round.
A good local place for mountain biking. Although the actual park is quite small there are many trail options, some steep but short climbs, a few log jams, jumps and twisty singletrack. We also night ride there and nobody has ever bothered us so it's a good local after work spot for those who want to keep in shape on the mountain bike.
