Byron Glacier Trail

OutAndBack • 2 mi • 100 ft

A short day hike to a view of a mountain glacier near the Begich, Boggs Visitor Center. Portage Valley is one of the most popular visitor destinations in Alaska, but don’t let that scare you away. The valley’s blue ice and glacial scenery is outstanding, and many visitors simply stop at the Begich,Boggs Visitor Center, enjoy the surroundings a bit, and leave for the next attraction. If you stick around for a short hike to Byron Glacier, you won’t be disappointed. Be sure to bring rain gear along, however, in case the valley’s frequent, pelting rains strike while you’re on the trail. Special features: A mountain glacier and a permanent snowfield.

BE ADVISED: this trail has been mismarked (submitting correction to editors). This is the Portage Pass Trail. Byron Glacier Trail is located near the Portage Glacier Visitors Center. Portage Pass Trail is located several miles east of Byron Glacier. Restricted access from the Visitors Center is through a tunnel ($12 car). The trail itself is quite easy. (I've seen plenty of non-hikers use the trail.) It takes just 20 min. to reach the high point of the trail with a reward of an incredible view of Portage Glacier.
