Dirk,
The hike through Enchanted Valley and Lacrosse Basin is one of the most (at least IMO) beautiful trips in the Olympics….A couple of others I've enjoyed is Seven Lakes Basin over Appleton Pass to Boulder and Happy Lakes ending at Observation Point……Dear Park to Grey Wolf River to Cedar Lake…….The transverse of Elwha River to North Fork Quinalt…….A couple of shorter ones (Good weekend trips – overnighters)….Upper Lena Lake and Scout Lake…..Royal Lake/Basin – one of my favorites. I'm partial to the Olympics for its diversity (Alpine Lakes to the Rainforests) and IMO unmatched beauty.
Hope to see you on the trail,
Christopher
