Lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver.[19] The boom ended by 1883 with miners deserting their claims.[20] The railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U.S. Route 34 from Loveland to Estes Park—was completed in 1904.[21] The 1920s saw a boom in building lodges and roads in the park, culminating with the construction of Trail Ridge Road to Fall River Pass between 1929 and 1932, then to Grand Lake by 1938.[22]
Grand Lake is arguably the biggest attraction in the town of Grand Lake, offering boating, sailing, fishing, swimming, kayaking and yachting – it even hosts a Regatta Week in early August.

Plus, as it sits near the western entrance of Rocky Mountain National Park, you’ll be steps away from one of the country’s most spectacular wildlife-filled parks too.
The Rocky Mountain National Park Act was signed by President Woodrow Wilson on January 26, 1915, establishing the park boundaries and protecting the area for future generations.[2] The Civilian Conservation Corps built the main automobile route, Trail Ridge Road, in the 1930s.[2] In 1976, UNESCO designated the park as one of the first World Biosphere Reserves.[6] In 2017, more than 4.4 million recreational visitors entered the park.[7] The park is one of the most visited in the National Park System, ranking as the third most visited national park in 2015.[8]
Brian and I descended back to ~7,000 feet for dinner in a small-town Indian restaurant in Nederland, Colorado, west of Boulder. By then, both our heads ached like a bad hangover, and my lungs literally burned when I tried to inhale anything but shallow breaths. Add generalized joint pain, and I had a full-blown case of altitude sickness. Given that I am a noted hypochondriac, I expected the worst.
