I hate to tell you this… because this is a favorite of ours.  We come here every year in the autumn.  We play on Kebler Pass, we have pizza at Stash in CB, and at night - the stars oh how the twinkle!  But you will pay a price for these autumn skies.  It is cold at Lake Irwin at night.  Bring a sweater and snuggle up!
The Camp Host is a delight.  So many sites that are good with peaks at the lake.  You are in the heart of the Rockies.  Wake up and pick a trail, or point towards a road.  It is bound to be beautiful!

We have stayed at this campground several times as it is convenient to Aspen and Maroon Bells, gives great access to Independence Pass, and each site has a secured bear box and tends to have some privacy.  However it has come to our attention that the information in the online reservation system regarding this campground is incorrect.  The Camp Host does nothing to alleviate the confusion, if fact she seems to take pleasure in adding to it, then announcing to campers they must depart once they have paid for their campsite and set up camp.  We witnessed this happen to about a half dozen campers over a recent weekend trip.  She behaves more like a Land Baron than a Camp Host, the title of her job.
I would take great care before setting up here, even if you have confirmed a reservation online.
