Head south out of Glenallen, AK on the Richardson Highway. After you reach the summit of Thompson Pass you will drop down into the entrance of Keystone Canyon about 14 miles north of Valdez, AK.
Visiting during the spring and summer is probably the safest time but a winter visit will give you some stunning winter vistas as well. Just bring chains and drive careful!
This is the entrance to Keystone Canyon just north of Valdez, AK. Beyond the canyon entrance are multiple waterfalls and breathtaking views.
