June 18, 2025, Dixon Reservoir

This little reservoir is dwarfed by the nearby Horsetooth Reservoir. Still, Dixon is a fun destination in its own right with a non-motorized boat launch and some easy mountain biking trails. There is also good fishing here (check local regulations).

The Dixon Reservoir is a small body of water at the base of the foothills below Horsetooth Reservoir surrounded by a protected Natural Area. The reservoir is a great fishing spot where many fish are stocked annually including pumpkinseed sunfish, bluegill, bass, channel catfish, black crappy, and grass carp.

The Pineridge Natural Area offers a handful of hiking trails and its own lake (Dixon Reservoir) on the eastern banks of the super popular Horsetooth Reservoir. You can connect to the Fossil Creek Trail using the trails on the property in case you want to stretch out your walk a few more miles.

The Dixon Reservoir is a small body of water at the base of the foothills below Horsetooth Reservoir surrounded by a protected Natural Area. The reservoir is a great fishing spot where many fish are stocked annually including pumpkinseed sunfish, bluegill, bass, channel catfish, black crappy, and grass carp. In addition to fishing, you can swim at a small beach on its northwestern shore, take out non-motorized boats, and hike around the reservoir on an attractive 1.8 mile loop, which links up with other trails in the Pineridge Natural Area.

September 11, 2023, Mount Olympus

Mount Olympus stands over the Big Thompson Canyon at 8,595 feet just outside of Estes Park. From the treeless summit you get some of the best, if not the best, views overlooking the town and some of the most famous peaks Colorado in Rocky Mountain National Park including the Diamond on Long's Peak and Mount Meeker; it truly is an amazing view. In large part due to the proximity of Estes and RMNP, Mount Olympus is somewhat overlooked. It is a great option, however, if you want a shorter hike at a lower elevation, want to escape the massive crowds often found at RMNP in the summertime, and get some great views. You can also hike with your dog here, which is not allowed in the National Park.

Molly Lake is a small, pretty lake just off the Granite Ridge Trail. You can camp at this lake, but please remember to pitch your tent at least 100 feet away from the water to help keep it clean for future users.
