Just added the Chena Dome Trail to our list of best hikes in the world.
Chena Dome is a very challenging 3-4 day adventure, 29.5mi (47.5km) loop mostly on ridgetop above the treeline.
It’s famed for great views and tasty berries in August. Finding water can be a problem late in the season.
About 50mi from Fairbanks, Alaska, this hike can be combined with a visit to Denali (Mt. McKinley), the highest mountain in North America.
I’m considering a trip to Alaska for summer 2007.
I started my research with Lonely Planet Alaska
.
Next I’ll need Lonely Planet Hiking in Alaska (Lonely Planet Walking Guides). I always start with Lonely Planet when planning a trip.

It is a good hike….if you come up here again try the St Elias Parks systems…specifically the Nabesna areas…good hikes…I’m planning a few down there in July
Thanks Mark.
I note a new train in the area called Mt. Sanford Plateau. THAT looks interesting.
