The weather in RMNP is extreme—and unpredictable. Ranging from snowstorms in the winter to hot, clear days in the summer, Rocky Mountain’s got it all. Summer is quick—just July and August—but beautiful, as temperature ranges from 40s at night and up to the 80s during the day. The rest of the year, expect snow at most elevations, and definitely up on Trail Ridge Road.

After your fireside meal, retreat to one of the private, wooden hot tubs tucked in the middle of the woods. A hand-held stroll along the forest path to a bubbling tub overlooking the city's lights will set the perfect mood. Take it to the next level and request a night's stay in the old firehouse on the tip-top of the mountain. There's no better view — maybe anywhere in the state.  
Sleep helped the altitude sickness, and after a full night in one of the research site’s cabins, I felt much revived. Brian fished in the morning and I scrambled up a rocky outcropping with a graduate student studying pikas through their poop (a non-invasive way to analyze stress levels of this small mammal that looks like a cross between a rabbit and a mouse): but our afternoon was free. What to do?

Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]
