What better way to rough it in style than to bunk down in a fire lookout on forested slopes? Built from the 1920s to '40s, cabins come with cots, tables and chairs, have panoramic views and can accommodate four people. Details about Little Mt Hoffman, Girard Creek and other lookouts can all be found on the national forest website.
Note that these cabins have become very popular and you'll need to reserve far in advance.
