Aleutian Range
Mountains Volcanic mountain range across southwestern Alaska
A volcanic mountain chain along Alaska’s peninsula, notable for active stratovolcanoes and glaciated peaks. Adventurers travel for remote mountaineering, backcountry skiing and viewing volcanic landscapes and coastal fjords, often accessed from regional hubs by small aircraft.
The Aleutian Range is a major mountain and volcanic arc in southern Alaska that extends from the Alaska Peninsula toward the Aleutian Islands. It forms the northern half of the Aleutian Arc and contains numerous stratovolcanoes and high peaks.
The range is characterized by rugged mountains, active volcanoes and glaciated valleys; it is a significant feature for geology, volcanology and remote wilderness recreation. Transportation and access are limited, with many parts reachable only by boat or aircraft and via sparse roadheads.
Geographically the range runs southwest from the Alaska Peninsula into the Aleutian chain and constitutes a key segment of Alaska’s Pacific coastal mountains.
- Volcanic arc activity: Many peaks in the range are volcanic and part of the Pacific Ring of Fire, so volcanic activity and seismic events are common in the broader region.
How to Get to Aleutian Range #
Access is via small Alaskan hubs. Major entry points are Anchorage or other regional airports; many parts require charter flights or boat travel from coastal towns like Unalaska or Cold Bay.
