We did the loop walk around Lake Estes on our first morning in town, I think the elevation change had gotten to me a bit and I wanted to take it easy the first day. As it was September when we visited, it was mating season for the Elk and there were plenty of them wandering around the lake, some even chilling off in the cool waters. We were warned not to get too close as they could be unpredictable that time of year so we did our best to keep a good distance. The walk itself was paved most of the way round and I think it was around 3.5 miles for a full loop. It was a very enjoyable way to ease into things. Seemed to be a popular place for jogging, cycling and dog walking too.
