Just back to UK after US holiday where this location was next on the list after a Seattle city-centre corporate hotel stay. Something of a contrast!!
Our tent-cabin was a wooden "shed" with mesh on the window openings (no glass) and a tarpaulin roof. No electricity, just a parafin lamp; all other facilities in the ranchhouse. This sounds quite spartan but don't be put off - its fine.
Food (we had a full-board tariff) is served in the ranch-house on long polished log tables and sawdust floor in front of log fire. Lots of choice and all very good. Help yourself to coffee from the big "always boiling" enamel jug on the fire. All overseen by the owner's family who make a point of keeping in touch
There is a shuttle bus along the valley from the boat jetty included in the tariff - this opens up the walking even for the most reluctant hiker and the commentary is fascinating, with the option to hop off at the patisserie.
And the location is of couse the real reason for going - remote, no access roads, just the 50-mile ferry ride along Lake Chelan, lots of hiking trails and adventure opportunities. We missed seeing the bear at Coon Lake, but probably just as well!
