Enos Mills, the main figure behind the creation of Rocky Mountain National Park, enjoyed walking to Lily Lake from his nearby cabin. Wildflowers are common in the spring and early summer. In the winter, the trail around the lake is often suitable for walking in boots, or as a short snowshoe or ski. Other lakes in the Wild Basin include Chasm Lake, Snowbank Lake, Lion Lakes 1 and 2, Thunder Lake, Ouzel Lake, Finch Lake, Bluebird Lake, Pear Lake, and Sandbeach Lake. Many of the lakes have backcountry campsites. Waterfalls include Ouzel Falls, Trio Falls, Copeland Falls, and Calypso Cascades.[47]
The famous hot springs of Glenwood is a must-see and do for all romantics. Located in Glenwood Springs, less than 3 hours from Denver, the historic and local family-owned Hotel Denver spans more than 100 years with many stories to tell, including Colorado immigrants, prohibition, gangsters, world wars, and even a Wild West shooting or two. This Colorado hotel has bragging rights to prime real estate in historic downtown Glenwood Springs, close to the train, many restaurants, shopping, the Hot Springs Pool, and our personal favorite, the Iron Mountain Hot Springs. 
At 265,000 acres, Rocky Mountain National Park isn't the country's largest national park, nor is it the most-frequented with about 4 million annual visitors (compared to Great Smoky Mountains National Park's more than 11 million visitors). But there is something definitively magical about RMNP, which rises 12,183 feet into the Colorado sky. The main attraction is hiking its 350-some miles of trails that wind through pine and spruce forests, glittering alpine lakes, swaths of wildflowers and if you're lucky, some elk or bighorn sheep. And maybe it's the thinner atmosphere that goes to visitors' heads, but even the most jaded report feelings of awe and wonder after a day or two of breathing in that refreshing mountain air.
Update on Jan. 14, 2019: A Rocky Mountain National Park spokesman said Monday the park began using recreation fees to temporarily pay about 10 percent of furloughed workers to clean up the park. They’ve been plowing roads, cleaning restrooms and collecting trash since Saturday. Other staff, such as law enforcement rangers, continue to work without pay during the shutdown. The park is expected to reopen to vehicle traffic on Tuesday, said Kyle Patterson, a Park spokesman who is on furlough.
