Mary Minerva McCroskey Memorial State Park Loop Trail is a 4 mile loop trail located near Potlatch, Idaho that features a great forest setting and is rated as moderate. The trail is primarily used for hiking and is best used from May until October. Dogs are also able to use this trail.
The area is absolutely beautiful, but there are little winding bits of trail all over and none of them are marked. The main gravel road had informational signs and mile markers regularly, but there is nothing along the trails themselves and nothing at the main park stops that tell you where the official trail heads are. There was a print-out map there so I used that and got royally lost on what was supposed to be a clear in-out trail according it. There are constant forks, splits and dead ends all over as well as defunct service roads - none of which are on their map. So what looks like a few clear trails is more of a spiderweb of paths and you're left guessing which is the 'right' one just to go the direction you'd originally headed out in. I had expected some sort of organization on-site but there simply wasn't any; I won't head out there again without either a proper map/compass or a GPS.
This park is full of opportunities for exploration. We hiked the "Mineral Mountain" trail today. It is really an old road, but very pleasant and we were the only people on it today. Evidence of other users (elk, deer, etc) abounded, however. The views from this trail were wonderful and my kids loved the ease of the hike. The gradual, circular climb led to the remains of an old fire lookout. We had lunch there and enjoyed the beautiful views from all sides. We got to hike through a bit of snow to get to it but it was just enough to be fun, not daunting and most likely won't be there much longer. You could backpack in and camp at the lookout site, but there isn't any water, so come prepared.
