All NJ state parks are $25 for non-residents.
Even for cyclists setting up a tent for the night? Wow. I realize every motel in the northeast is $175 minimum. But it still seems exorbitant.
Yep. Just did a three-day to a NJ state forest campground this past weekend. It's $20/night for residents and $25/night for non-residents. And dig this: They now use Reserveamerica.com for reservations. It charges a $9.50 transaction fee on top of the nightly rate. I live in PA, so my two nights of camping cost me $59.50. I consider reserveamerica to be the TicketMaster of campground reservations. The site for NJ state parks is really obnoxious in that it doesn't list a reservation phone number. They obviously want to frustrate people to the point where they will set up an account and reserve on line. The obvious reasons are: they get your email address and it saves on labor costs.
But wait! There's more! If you don't make a reservation and simply show up and request a site at the office they charge you a "reservation fee" even though you didn't make a reservation. IIRC, when I did that at the same state forest last year they charged me a fee of $5/night.
Neither PA not NJ have hiker-biker sites. PA parks tend to be a bit less expensive. It varies by park. I think the fees are usually in the high teens to low 20s. Same rate for non-residents. When I crossed PA last year I stayed in mostly private places. I think I paid $26/night for the most expensive place, $18 or $19 for one state park and between $22 and $24 for the other private places. One place--a township park along a popular trail--was free.
You can find cheap motels if you know where to look. I know a couple of places in the Delaware Water Gap area that are $100/night or under depending on the day.
