Is the NJ State Long Trail dog-friendly?

Policies regarding dogs can vary by specific park, preserve, or municipality that the NJ State Long Trail passes through.

It's always best to check the local rules for the area you plan to visit.

What is the best time of year to hike the NJ State Long Trail?

The best time to hike depends on the section and your preferences. Spring offers blooming wildflowers and milder temperatures, while fall provides stunning foliage.

For example, segments near Frenchtown are noted as "Easy," and a 5.7 km loop in Lebanon includes part of the Highlands Trail.
