NFS staff spread misinformation
Visited 8/2020
We really like this area! Tarryall Reservoir is an awesome location. To update from a different review; the ONLY camping is dispersed. There is a day use only area next to the reservoir with no overnight camping. Also, there is no water available, so bring plenty of water with you.
We were camped initially just off of an established 2-track road that was connected to Tucker Gulch Rd/County Rd 23. Members of our party had been camping in the exact same location for over a decade. Our campsite was consistent with every other dispersed camping I have ever done on NFS land.
After our first night, NFS staff came into our camp stating that we were camped illegally, couldn't make our own roads (again, we were off a 2-track road that was marked on maps of the area), and could not be more than 25 feet from an established and marked NFS road. After we packed up to move to another location, we noted brand new signage that was most certainly not there until after the staff members informed us of our "violation".
After relocating we parked within 25 feet of a marked NFS road. This was right next to other camps that were at least 200ft from the same road. Camping within 25 feet of the road brought with it heavy dust and noise from vehicles and UTV/ATV traffic.
With all of this said, the area is amazingly beautiful and the distance from the metro area is perfect. The area is huge with plenty of 4WD and non-4WD (one member in our group had a travel trailer) roads to find the perfect camping spot for you. We will definitely be going back even with our sour run-in with the NFS. And just to throw it out there; I love the NFS and I believe they're generally pretty awesome!
Note: After getting back in town and re-educating myself on San Isabel NF specific rules and regulations, I could not find anywhere where it states the 25 foot rule. Plus, I confirmed that we were not violating any rules.
