We spent four nights here and really liked it. Nicely maintained campground (impeccably clean washrooms). It was very obvious that lots of energy has gone into building this relatively new campground. In a few more years when some of the trees mature and provide shade, this will be high on our list of recommended campgrounds in the area. Only knocks would be very poor Wi-Fi and I wished they would have used a finer aggregate for the campsites. We camped here in a Travel Trailer.
We were in the group camping area for a rally. Regrettably, the sites in this area were relatively small back-ins with a fairly steep grade. Our site was much higher in the rear but others in our group were very low in the rear. Also these sites were only 30 amp & did not have sewer service. The park has pull through sites with sewer, water, and a mix of both 30 amp & 50 amp service. A little surprised that a new park doesn't have 50 amp & sewer at all sites. The RV park is part of a Garden Center with a 1887 Pullman Dining Car that is used as a restaurant. Mossleigh is less than an hour from Calgary. We camped here in a Fifth Wheel.
