Silver Mountain Resort is a year-round resort in Kellogg, Idaho, located 70 miles east of Spokane and 30 miles east of Coeur d'Alene. In the winter, families can go skiing, snowboarding, and tubing, while popular summer activities include chairlift-assisted mountain biking and hiking and geocaching. But this summer, the big buzz has been all about the brand new, giant indoor waterpark where the temperature is always a balmy 84 degrees. Silver Rapids Waterpark has a lazy river, multi-activity pool, family raft ride, several single and double tube rides, dozens of interactive waterplay features, a gigantic tipping bucket, and a FlowRider surfing machine. From now through September 30, the End of Summer Sale offers a stay-and-play package starting at $149 a night for family of four. For each night at the Morning Star Lodge, you get two days of admission to the waterpark.
