You do not want to stay on the west side of Rocky Mtn NP as all the major activities are on the east side; some 45 miles away and up over the Cont Divide.
We had dinner with former neighbors from Estes Park last night. Hwy 34 up is in pretty good shape but some sections lack the guard rails and all. Think it can be done in an RV with some real caution. REAL caution.
I understand Fall River Road will be closed all 2014.
If you are going to the "mountains" I am not sure why you are looking at Central City - mainly a lower level gambling area. Depends on what you are looking for.
If you can, head over to Buena Vista / Leadville area. We really love that area and Black Canyon and all.
Estes can use all the support it can get but make sure to check out things you want to do and places you want to visit very carefully before making decisions.
