Girdwood is a resort town within the southern extent of the Municipality of Anchorage in the state of Alaska. Located near the end of the Turnagain Arm of Cook Inlet, Girdwood lies in a valley in the southwestern Chugach Mountains, surrounded by seven glaciers feeding into a number of creeks, which either converge within the valley or empty directly into the arm. Girdwood is typically accessed by the Seward Highway (Milepost 90), with the main line of the Alaska Railroad paralleling the highway. By road distance, most of the community lies within 35 to 40 miles (56 to 64 km) of downtown Anchorage. According to 2014 estimates, a little under 2,000 people live in the valley.
Founded as a community to supply miners during the Turnagain Arm gold rushes of the 1890s, Girdwood was mostly a small, quiet place until the middle of the 20th century. Two events drastically altered that. The first was the establishment of Alyeska Resort along the slopes of Mount Alyeska, which became an international destination coincidental with Anchorage's civic promotion of itself as "The Air Crossroads of the World". The second was the 1964 earthquake, which devastated the original townsite located directly along the arm. Following the earthquake, most of the town moved further up the valley to a new townsite, though a few homes remained and a strip mall was later constructed along the Seward Highway. Historically dominated in the years since the resort's opening by seasonally-occupied vacation homes and seasonal activity at the resort, the opening of the Alyeska Prince Hotel during the 1990s has shifted the resort, and hence Girdwood as a whole, more towards year-round activity and a year-round economy. This has led to periodic debates about community growth and affordability of housing for resort workers, many of whom over the years have resorted to camping illegally on public lands.
Girdwood still revolves heavily around seasonal activity, with skiing and snowboarding at Alyeska Resort bringing visitors and their money into the community. Summer activities are also popular, which include hiking, fishing and rafting. The Girdwood Forest Fair, held every July, is the community's most significant visitor attraction apart from resort-related activities. Girdwood is located within the northernmost extent of rain forest on Earth, and also serves as the closest point of access to Chugach National Forest from Anchorage proper.
