We'll be lodging in Estes Park from Oct 13-18, after the shuttles cease operation. Which hikes (under 10 miles and appropriate for people with a fear of heights) should we consider? We have 4 days, no kids, and would like to incorporate a horseback riding trip at some point. We are in good shape, but would prefer nothing over a high moderate rating as we will have to acclimate to the elevation. I'd love to find some compliment of lakes, falls, wildlife, and panorama, if possible. Thanks.
