I have been to RMNP a couple times but never found a good forum on the park. 14ers.com will cover some of the mountains there, and PMags.com is a great site for general Colorado backpacking. The Wild Basin area of the park is great for getting away from most of the crowds. Prior to entering that area of the park we stayed at The Dao House hotel as it was very close to our trailhead and kept us out of the giant traffic jam that is Estes park.
