Bring sunscreen and plenty of water! I did this loop counterclockwise. Arthur’s Rock Trail is a well populated trail. I arrived at 8:30am and the upper parking lot was almost full. It took about 50 minutes to reach the summit of Arthur’s Rock. Timber Trail / Westridge Trail have less people traveling on it. The trees create a nice break from the direct sun. These are multi use trails and I did see a handful of mountain bikers however, I had Westridge practically to myself (only passed one other person). Howard Trail / Mill Creek Link Trail winds you down variety of switch backs where you can enjoy a plethora of wildflowers getting closer to the reservoir. You can easily truncate this loop into a 6.5 mile outing by eliminating the South Valley Loop section. The valley though is very pretty and extremely mellow, so it’s a nice add if you’re looking for the extra mileage. I also tacked on Shoreline Trail, just a quick little trail but that is the closest to the reservoir that you can get during the loop. All in all, I had a fantastic morning exploring this Colorado State Park! RT it took me 4 hours and AllTrails recorded 10.5 total miles.

Mostly shaded, nice and easy
