Mount Arriva is an 8,215 ft (2,500 m) elevation mountain summit located in the North Cascades in the U.S. state of Washington. It is situated in North Cascades National Park, on the shared border of Chelan County and Skagit County. Despite its position only 1.55 mi (2.49 km) southwest of Easy Pass, and 3.7 mi (6.0 km) west of the North Cascades Highway, it is not visible from either. Its nearest higher peak is Black Peak, 2.57 mi (4.14 km) to the southeast. Mount Arriva has a secondary summit, called East Peak (8,160+ ft), which was first climbed in August 1940 by Fred Beckey, Jim Crooks, and Ed Kennedy. The first ascent of the true summit (West Peak) was made July 6, 1966, by Joe and Joan Firey, John and Irene Meulemans.
