We're doing a long weekend in Jackson in February. We're planning on snowshoeing in the Elk Refuge and possibly GTNP. Are there other areas that are good for either snowshoeing (we're bringing our own) or cross-country skiing (we would probably rent)? The Snow King website mentions both cross-country skiing and snow shoeing, but it's hard to tell if it's actually on their property. We're staying in a townhouse near Snow King.
