Turnagain Arm

Overview

One of the biggest draws to Alaska is its unparalleled natural scenery, and Turnagain Arm is one of the most beautiful—and potentially dangerous—places to visit near Anchorage. Turnagain Arm is a waterway that empties into the northwest portion of the Gulf of Alaska, and it is one of two branches of Cook Inlet that are known for their extreme tide ranges, dangerous mud flats, and stunning views.

About Turnagain Arm

Arguably one of the most beautiful stretches of American highway, Turnagain Arm can be seen from Seward Highway that hugs its dramatic shorelines. With some of the largest tides in the country, the waters of Turnagain Arm can rise 40 feet at high tide—with low tide exposing expansive mud flats cut by stream channels.

Geography & History

Turnagain Arm was named as a result of an expedition party in 1778 that was on a mission to find the Northwest Passage. William Bligh led a part up Turnagain Arm only to report back that it led to a river—in frustration, the Bligh named the body of water “Turnagain River”.

Turnagain Arm flows east to west and is over 40 miles long, forming part of the Kenai Peninsula’s northern border.
