My wife and I are visiting my sister in Denver at the end of September. My wife and I have from Friday through Tuesday (flight leaves Wednesday morning, so 4 nights) and my sister can join us just for the weekend (Friday and Saturday nights). Ideally my wife and I would be able to make full use of the 4 days for a more immersive experience, but my sister will need to be able to duck out via a hopefully not-too-long possibly-solo hike back to her car. This makes for an interesting trail-finding constraint. Any suggestions?
RMNP is out due to road construction and their annoying regulations. All three have us have some experience mountaineering (and I have lots) so some scrambling or snow travel is no obstacle (though climbing is not the main intent on this trip). It's not totally necessary, but drives under 3 hours from Denver will be awarded bonus points!
Thanks for any suggestions!
