I used Rainbow House for a brief stay at NCNP as part of a long-form hiking trip that spanned the PNW. This house could not be better suited for people looking to relax and/or enjoy daytrips around the greater national park area. It is very conveniently located between Cascade River Rd. & the Ross Lake NRA, making it easy to feel like you're never far away from any of the more accessible views & trails.
As far as the house goes, this is a spacious, very well-maintained property and honestly better than I was expecting, given its rural nature. Huge open yard, lots of space inside, OUTSTANDING views, and everything I used was in working order - not that I used many things in the house, because all I really ever did in the evenings was sit on the covered porch and enjoy the scenery with a cold beer. Washington will never be able to complete with Big Sky country for sunset vistas, but Rainbow House comes close - it feels like you're sitting in a PNW version of the Yellowstone Ranch.
Many thanks to Steve for his quick response to my inquiries and allowing me to use his outstanding property. I don't know when I'll be able to make it back to North Cascades again (too many other places to see!), but when I do, I'll be looking this place up again.
