Valley RV, or Arrowhead Point. Both on north end of town, Arrowhead a little farther out. Stayed in Valley for a month, and loved it! Best rates. Friendly folks!
Routes - you can take US24 west out of Colo Spgs. It's a steady climb to Divide, and a steady climb ro the top of Wilkerson Pass. Take your time, don't push your engine, enjoy the views. Cross South Park, watch for Pronghorn on the road, another small pass, and you're there.
OR...
If you don't have to go through Colo Spgs... Exit I25 the north end of Walsenburg, fuel up, and take CO69 towards Westcliffe, to Texas Creek, on the Arkansas Rvr. West on 50 to Salida, then north on 285 to Buena Vista. Maybe stay overnight at Grape Creek RV, 1 mile south of Westcliffe.Small park, neat as a pin. Gorgeous views. We just came up 69 this weekend, north of Westcliff is as breathtaking as you'll find in CO!! NO steep passes this route.
Actually, if you watch for CR1a, just north of Hillside, on the way to Texas Creek, you can go to Cotopaxi, instead of Texas Creek. This will shave about 5 miles off, and the road is just as good. PAVED ROADS all the way, I have travelled this with our Bighorn 3670 - it's a nice easy drive!
