This is a very busy park in summer, & we arrived without a reservation & wanted 30 amp. Nevertheless, the staff found us a site. The park has expanded their 50 amp area, & it's nice, but you'll probably need a reservation. The private showers are terrific, & really clean.
This is a great park for big rigs! Wide, level, pull-through sites & easy access were a hit with us. The owners, were so friendly & helpful on our first visit that we kept adding days to our stay so we could experience more of the Terry MT area. And we have kept coming back! Do we recommend this park? Yes!
