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]
The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world.
Depending on when you choose to stay in an Estes Park vacation rental, you may be able to catch family-friendly events like the annual Teddy Bear Picnic or Longs Peak Scottish-Irish Highland Festival. If you aren't able to make it to those events, don't worry: you can always pick up some local history at the Lula W. Dorsey Museum or Stanley Steam Car Museum. Visit the local shops and galleries like the Wild Spirits Gallery or Alpenglow Images & Accents to see some local photography, woodworking, jewelry, and other crafts or pick up a souvenir or two for friends and family back home.  

The recreational activities are what draw most people to Maroon Bells. The hiking here is incredible, with all kinds of day hikes and backpacking areas. Mountain biking trails cover hundreds of miles. Fishing in lakes, ponds, rivers, and streams is popular in summer. In winter, people come here to ski, snowshoe, and snowmobile, making it a year-round outdoor playground.
The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.
