What do you want to see? Lakes? Peaks? Animals?
How far are you wanting to hike? Ouzel falls isn’t bad effort wise and was mentioned earlier. Alberta falls and emerald are real popular I believe but can get crowded. Emerald is really a must do if you haven’t been there.
We will be doing plenty of long hikes (girls and wife are in good shape it's me I'm worried about!!) but looking for things to do that are more restful on a couple days. Either in Estes Park or we might spend a couple days at Grand Lake also. I loved the idea of going to the continental divide and watching a sunset.
Any secluded hot springs in the area or a good swimming hole?
