Portage Pass is a snowkite spot in south-central Alaska, between Portage Lake and Passage Canal (Whittier). This mountain pass offers spectacular snow-covered terrain surrounded by glaciers and alpine peaks. Katabatic winds descend from the glaciers (notably Portage Glacier) and funnel through the pass, creating reliable winter wind conditions. The terrain is relatively flat at the bottom of the pass, ideal for snowkiting. Access is from Whittier via a hiking trail (Anton Anderson tunnel). Snowkite season runs from November to April depending on snow coverage.

Extreme cold — risk of hypothermia and frostbite. Extreme cold weather gear mandatory (dry suit, thick gloves, face mask). Avalanches possible on surrounding slopes — check avalanche bulletin before each session. Glacier crevasses in the glacier area. Portage Lake ice may be unstable — check thickness. Wildlife: bears (brown and black), even in winter (occasional wake-ups). Weather conditions changing rapidly — sudden blizzards possible. Remoteness — rescue services very far away.

The frozen lake surface offers an extended flat area but check ice thickness before venturing out. Typical winter temperatures from -15°C to -5°C (5°F to 23°F). Extreme cold weather gear mandatory.
