Kooser is a nice little park set amid large tracts of public lands. There's a pretty lake where people fish and picnic, though the swimming beach is probably not going to reopen. The cabins are beautiful and nearly always booked--despite the fact that they sit awfully close to a noisy state highway. There's only one hiking trail within the park's 250 acres. But it's a decent trail with sharp elevation gain. The campground is popular, so you have to book early for Memorial Day of Labor Day. But as a tent-camper, I didn't find Kooser to be ideal. The whole campground has been recently restructured to allow for more big rig camping. Most sites sit in the full sun, and they have electrical hookups for air conditioning and the bane of the forest: radios! There are really only three little tenting sites in a wooded area of the campground, a little higher up the hillside. But the place is well-maintained. The showers are nice. There's a great playground for kids. So if you've got a trailer and a pack of kids, this is your place. If not, consider a night of backcountry camping in the nearby Forbes State Forest.
