Some Estes Park (east) and Grand Lake (west) entrance lodging options for Rocky Mountain National Park. I recommend staying in Estes Park the first two nights and Grand Lake the last night.
The first day in Rocky Mountain will be an easy, low key one. These easy walks make it great to adjust to altitude if you're visiting.
How to spend the second day at Rocky Mountain. The first four are all part of the same trail!
How to spend the 3rd day in Rocky Mountain National Park. This will include a scenic drive over to the west side for some easy hikes. *This day 3 itinerary works in summer months, as Trail Ridge Road closes in winter.
