I parked my car at the hiker parking lot at Wild River Campground Oct 1 -3, 2022 I did a backpacking trip into the Wild River Wilderness and up to Mt. Moriah. Since I didn't actually camp here or use any other facilities (except the bathroom, which was fine/clean/typical) I can only say of the campground itself that it looked very clean and nicely laid out, with attractive and large sites. However I want to share a few updates others may find helpful:
a. A sign at the start of the gravel rd around 5 miles N of the campground says there is no potable water at the campground.
b. At the time I'm writing this review, google maps shows the road ending near where Bull Brook meets the Wild River, about 0.7 mi north of the campground's location (down near Blue Brook meets the Wild. This is not true. The road actually continues all the way to the campground.
c. The cable-suspended wooden walking bridge shown in Jim Armstrong's review from 3 years ago is no longer there. That bridge used to go over the Wild River, connecting the Campground side to the Moriah Brook Trail. Alas it has been washed away, and the only way to get from the east side of the river to the west down at the campground is to ford the river (walk through it). That was easy to do with care in early Oct 2022, but I can imagine it might be quite dangerous or impossible in higher water. Cross at your own risk!
d. Nadja Mayumi's review says "There is no hiking from the parking lot to the spot." That may be related to my comment b above, as google maps makes it look like you have to take a trail from the end of the road to reach the campground. But, just to be clear, there is tons of beautiful hiking in the area, on many trails that start there, or pass right by. The Basin Trail heads SE from there, and the Wild River Trail SW, both on the east side of the Wild River. And if can ford the wild river, the Moriah Brook, High Water, and Shelburne trails lead W, S and N.
