Thunderbird Falls is only 30 minutes outside of Anchorage right off the Glenn Highway. It's a short hike that ends at a picturesque 200ft high waterfall.
Thunderbird Falls is just 1 mile from the parking area off the Glenn Highway. The trail starts off with climb but quickly levels off. It skirts the Eklutna Canyon through a birch forest with viewing decks overlooking the cayon and falls.
The trail splits near the end. If you stay to the right you will reach the overlook which is only about 100yds further on the boardwalk. Going left will take you to a creek side trail leading to the base of the falls.
The Alaska environment changes drastically with the climate. In the colder months the falls freeze and create blue ice formations. During this time the trail may be extremely icy. Be very careful and make sure to bring a pair of crampons.
