Turnagain Arm is a scenic waterway located in Alaska, just south of Anchorage. It is known for its stunning views of the surrounding mountains and its unique tidal phenomena, which can create dramatic changes in water levels. The arm is part of the Cook Inlet and is approximately 30 miles long. The area is also popular for outdoor activities such as hiking, wildlife viewing, and photography. Visitors may spot beluga whales, sea otters, and various bird species. The Seward Highway, which runs alongside the arm, offers easy access to its breathtaking landscapes and recreational opportunities.
