We are two 30 year olds visiting Denver this coming week (July 19 pm -22 am). We'll really only have 2 full days to explore (Wednesday and Thursday) and would like some suggestions for day trips? We'd like to do some brewery tours/beer tasting, I heard New Belgium in Ft. Collins was good but their tours are booked, I've done Coors before, we were thinking maybe we should just head to Boulder for the day? Also, perhaps the other day, we should go to Estes Park and RMNP? What would be a good itinerary for one day in each of those places? (We have to return to downtown Denver each night). Or Ft Collins? Or something else in downtown Denver? (Anything going on this week in particular?) We are up for anything (I like history too) but are budget-minded. Thanks!
