I entered Rocky Mountain National Park at the Grand Lake Entrance Station on the west side. My campsite was aaaall the way across the park at the Moraine Park campground on the east side. That meant that I had to cover nearly the whole length of the 48 mile Trail Ridge Road, cross Milner Pass at 10,758 feet, then the aptly named Highest Point on the Road at 12, 183 feet and travel through three ecosystems just to set up camp. Wahoo!!
Part of the appeal of Rocky Mountain NP is the diversity in terrain. Montane (below 9,000 feet) leading up to Sub-Alpine (9,000 – 11, 400 feet) leading up to Alpine (above 11, 400) with the flora and fauna that comes with each ecosystem. That and the plethora of spectacular views at 12, 183 feet.
