Portage River is about a forty five minute to hour long drive from Anchorage. It is right past Girdwood. Portage often has warmer temps than other ice climbing areas, so conditions here might not always be the best. The climbs range from single pitch to multipitch climbs. Climbs up to WI6 and mixed conditions.
Drive South on the Seward Highway past Girdwood, you will see signs on the road talking about the Portage Glacier. Turn there. The climbs will be on the left and primarly the right side of the road. Ski or hike to all of the climbs. Beware of avalanche conditions.
