Sunday River is a ski resort located in Newry, Maine, in the United States. It is one of Maine's largest and most visited ski resorts. Its vertical drop of 2,340 feet (710 m) is the second largest in Maine (after Sugarloaf) and the sixth largest in New England. Sunday River has the most terrain among the East Coast skiing destinations, including eight different peaks. The resort features 135 trails across eight interconnected mountain peaks, and is serviced by a network of 18 lifts. Sunday River and its sister resort Sugarloaf have been operated by Boyne Resorts since being sold by American Skiing Company in 2007 for a combined $77 million. The resort's land has been owned by CNL Lifestyle, then Och-Ziff Capital Management, and leased back to Boyne. In 2018, Boyne Resorts completed the purchase of all leased ski areas in New England from CNL Lifestyle, allowing Boyne to "accelerate and fine tune" investment in those areas (Loon, Sugarloaf, and Sunday River). In direct correlation with this event, Boyne announced a list of improvements for all three mountains, to be spread out over a span of 10 years.
