The first time I went was summer of 2002 for the Fourth of July, had a great time riding bikes playing with radio controlled cars and hanging out by the pool. We drove down to Crater Lake as well which was incredible. Theres also a great candy store in town. I came back for new years eve the same year and went snowboarding at Mt Bachelor. SunRiver is a great place any time of year, and just the drive from Portland is worth it.
