During the summer they offer guided horseback trail rides.
During winter they do guided snowmobile tours and also offer snowmobile rentals. Ever year they buy an entire new fleet of top-of-the-line snowmobiles. They run them through the winter and then sell them all during the spring and summer, to make room for a new fleet that fall.
They are open year-round and also offer other activities, depending on the season.
I highly recommend them for lodging, horseback riding and snowmobiling. They run a first-class operation. (See photos of the lodge below.)
