1) There is a dog park near Lake Estes, at the intersection of Hwy 36 & Community Drive.
2) Dogs are allowed inside Rocky Mountain National Park as long as they are leashed and kept by the roadside.
You cannot hike with your dog in Rocky Mountain National Park, but you can drive through with your dog and stop for a picnic, etc.
You can hike with your dog in Roosevelt National Forest, adjacent to Rocky Mountain National Park. Some of the trails mentioned below are on National Forest land.
3) Lily Mountain is a short trail (just over 3 miles round trip) to the summit of Lily Mountain. It is one of our favorite places for hiking with dogs in Estes Park.
The trailhead is located on Hwy 7, about 10 minutes south of Estes Park, on the right hand side of the road. The sign is fairly small but there are usually cars parked there. It is on Forest Service land just adjacent to the National Park.
4) Kruger Rock is another short trail, 3.4 miles round trip, with outstanding panoramic views from the summit.
The trailhead is located at Hermit Park, a Larimer County Park. The entrance fee is $6, but the hike is well worth it. Hermit Park is about 2 miles outside of Estes Park on Hwy 36, near mile marker 4.
There is another trail leaving from Hermit Park that accesses Homestead Meadows, which has an assortment of old homestead cabins and is very interesting.
5) You can also reach Homestead Meadows via the Lion Gulch trail, located at mile marker 8 on US Hwy 36. There is no fee to use this trail, but the hike is somewhat longer and steeper than the trail from Hermit Park. Note: this trail was heavily damaged in the 2013 floods, and the trailhead may not be open.
Many of the hikes on this Estes Valley trail map are good places for hiking with dogs in Estes Park; just pick the ones that are not in Rocky Mountain National Park.
