Ely KOA is fine for an overnight stop. There is plenty of room to maneuver and facilities were adequate. Some with bigger rigs might have difficulty, so I would call if your over 40 foot.
The office staff was okay, not overly friendly but that may have just been her personality. I was impressed with the cable, lots of channels and pretty good reception. WiFi was fine for the price. We were there in mid November and it was cold, woke up to frost on every thing. We didn’t hook up the water and glad we didn’t as might have froze. There was no one there to help us with propane when we pulled out and that was a bummer.
If your coming in on Hwy 93, you won’t have any problem finding it, its on the west side of the highway just south of town. On the other hand, if your coming in on Hwy 6, turn south on 93 where Hwy 6 T’s and it’s about a half mile down the road.
