Route overview

Most itineraries use Ashford, Trout Lake, and Castle Rock as the key access bases for Mount Rainier, Mount Adams, and Mount St. Helens, with summit days linked by transfers rather than one continuous trail. Arrivals from the UK usually begin with london -> seattle (or portland), then self-drive/van support before the route moves on between the mountain bases.
