We went on a two week self-supported bicycle tour in 2010 and rode into Walden after covering 73 miles on loaded touring bicycles, up from Grand Lake. The Antlers Inn is a wonderful surprise in such a quiet town. The hotel doesn't look like that much from the outside. It looks like a good bar rather than a quiet, well priced, nicely appointed hotel and restaurant. We don't make reservation when traveling on the bikes but it was "no reservations, no problem" and the staff was very polite and accommodating. They let us lock our bikes up in an unused storage area which was great. The hotel rooms are well done and quiet. You'd be hard pressed to find hotel rooms like this in similar towns found in the region. We ate at the attached River Rock Cafe for lunch and dinner and it was pretty good overall but not as much of a bargain as the hotel rooms are. The wait staff were very nice.
While I'm not sure what would draw me to Walden, for those passing through in need of a good night's rest, The Antlers Inn is your best bet within several hours drive, or a day's bike ride.
