Lewis Morris Park is a medium-small sized park with a very high level of maintenance. There is hardly ever a stick in the trail, let alone a log. In the fall the leaves are literally blown from the trails. There are nicely constructed micro gravel paths yet many sections with an overload of roots. Plenty of climbing, steep but short, nothing sustained. The high quality of the trails makes the descending fast and fun, especially the last half of the yellow trail going clockwise.
From 287 take exit 30 to Childs Road. Make the first right onto 202/N Morristown Road. After about two miles make a left onto Temple Wick, and eventually a left onto Corey Lane. In 1.5 miles turn Mendham Road, and the parking lot will be on your left in about a mile.
