I have only been to Denver once, almost 10 years ago, and visited Golden, Boulder and the RMNP.
We will be in Denver for a meeting, but will have two weekends to visit other areas.
I'm interested in the mountains, hiking, walking...
Are the gondolas, cable cars etc., running during summer?
Been trying to read about the different areas, but they don't seem as simplified as the Berner Oberland area (for example), in Switzerland so I'm a bit confused.
