If you stay on the Centennial side it's a 6 mile trailer up to Greenrock parking. From there you follow the trail, it goes over Libby Flats about 4 miles out, past there you're golden. I never go over Libby, most of us will cut off the trail thru Libby Creek and make a short cut below the mtn and meet back up to the trail at Belamy Lake.
Now on the west side you have Saratoga, lots places to stay and about a 30 minute trailer to riding. The Rondesvous, 10 Mile Inn, and Medicine Bow Lodge are all on the trail and you can ride from your door.
Gotta go, looks like it snowed all night............headed up now.
