However, when the neophyte hiker has completed the day hikes, one at a time, the next challenge will be to repeat the whole performance as one 42-mile overnight hike. Some additional equipment will be needed but there is enough time before the fall to acquire what is needed. It's worth it. The trail in the fall is especially beautiful and secluded and the hiking temperature will be ideal. There is little on the New Jersey section that can be considered dangerous if some common sense is utilized.
Snakes are rare.
I've never seen a poisonous one on the trail in New Jersey but some hikers have. Treating them with respect is certainly sensible. Bears are around but they're skittish and are seen occasionally. Some years ago I did a little hiking on the trail in Maine, confident that in Maine, at least, I'd spot a bear. With any overnight hiking it is a good idea to bring along a light tent in case of rain.
