Gustavus is split by the Salmon River, across which there is a bridge for the paved road running out to Glacier Bay National Park. Coho salmon, Dolly Varden, and other fish are commonly caught in this river. Gustavus lies on the outwash plain created by the glaciers that once filled Glacier Bay. It is located 48 air miles west of Juneau, Alaska's state capital. You can arrive by plane or boat as there are no outside roads connected to the area. Attractions include saltwater fishing and natural history boat charters, kayaking, flightseeing, whale watching tours, golfing, biking and hiking. Gustavus also has local cafes, galleries and gift shops. Summer temperatures range from about 52–63°F (11°C-17°C) and winter temperatures are 26-39°F (-3°C to 4°C).
