The Turnagain Arm is a waterway into the Gulf of Alaska, one of two branches of the Cook Inlet. The Turnagain Arm Drive is the 50-mile stretch from Anchorage to Portage Glacier, known for being one of the most scenic drives in the world. Snow-capped mountains and glaciers provide the backdrop along Chugate State Park. Some of the wildlife that can be spotted here includes bald eagles, beluga whales, moose, elk, and Alaskan wild salmon. There are numerous hiking trails along the Turnagain Arm, including the Turnagain Arm Trail which follows the highway.
Turnagain Arm is known for its high tides and particularly the bore tide, which is a series of waves reaching as high as ten feet as they travel from the bay to the shallower inlet. Because of the surrounding mountains and size of the waves, the bore tide at Turnagain Arm is considered to be one of the most beautiful in the world.
To visit the Turnagain Arm, head southeast along the Cook Inlet from Anchorage on Seward Highway.
