If you only do one hike in Alaska, it has to be this one! We clocked 10 miles to a stunning Lost Lake view (more if you go to the lake). My feet hate me and it took me all day, but it's worth every minute. The trail is well maintained. There will be a few muddy patches after several days of rain, but not a real issue. You will travel from lush rainforest to above the treeline for jaw-dropping vistas. The approach from Primrose is less aggressive but still plan for a serious hike. Bring bear spray because it's Alaska - not one sign of bear though. You can also grab a great shot of a really cool waterfall just off the trail. Blueberries are everywhere!
