Frelinghuysen Arboretum is the beautiful arboretum in Morristown, NJ. We've picniced on the large lawn, walked the trail, visited the gardens and toured the gift shop all with small children in tow. It is a calm place to get inspired to work in your own garden. The gift shop has many unique gifts for the whole family. Well worth a visit during the gingerbread house display during the holiday season, as well.
