This is just a preliminary question, so no need for readers to worry overmuch about the best answer.
I'm toying with the idea of persuading my partners to section hike a s bit of the CT next August. I'm attracted by the scenery, the high elevations, the promise of well-posted trails, and the absence of bear canister requirements (unlike Cali.)
So we would be interested in a scenic, high, and adventurous section 160 km (100 miles) or so long, to be done in 5 or 6 days. We're not afraid of steep trails, isolation, inclement weather, or navigation.
Less interested in sections that require packing large amounts of water or sharing the trail with motorized vehicles (ATVs, dirtbikes, etc.).
A loop trail, not necessarily on the CT, that doesn't require a vehicle shuttle would also be very atrractive.
I've already downloaded GPS tracks of the entire trail and a digital topo map of Colorado. We have 70+ years of mountaineering experience between the three of us and hiked a 95 mile (150 km) section of the Great Divide Trail, gaining and losing about 6000m (20,000 ft) of elevation and crossing 11 mountain passes over 5 days last summer.
Any suggestions, especially from Coloradans, welcome!
