Lake Minnetonka’s glory days began after the Great Northern Railway extended their line into Spring Park around 1882. More than fifteen trains per day pulled into Spring Park bringing hundreds of tourists to the area. In 1885, James J. Hill began construction on the Hotel Del Otero. Visitors either arrived by steamer to the hotel’s dock, or by train. The railway depot was located just a few yards northwest of the hotel.
Hotel Del Otero was a sprawling three story structure situated on a large knoll. It boasted a large ballroom, screened promenade, and well appointed sleeping rooms. For recreation, the hotel provided sailboats, lawn bowling, croquet, private beaches, a casino, and a dancing pavilion with live music. In 1906, James J. Hill sold the hotel to George F. Hopkins and Company. Hopkins maintained the hotel, the dance pavilion, a ball park, and picnic grounds until 1918 when Adam King became the proprietor.
Hotel Del Otero burned down on July 4, 1945. The fire-scorched shell of the hotel stood as a reminder of Lake Minnetonka’s heyday well into the 1960s. Today, the Mist Apartments on Shoreline Drive occupy the site of the hotel. Just to the east were the hotel’s rental cottages, and the casino was located where the Hennepin County Water Patrol headquarters are located today. The railroad tracks were removed and turned into the Dakota Rail Trail for recreational use.
