Update: I tried both the John Muir Trail and the Colorado Trail last summer, and one was a clear winner for me.
I did the JMT over 21 days in July and the CT in 28 days starting in August. The scenery on the JMT is unreal, no question, but the sheer number of people and the permit hassle really wore me down. I felt like I was in a line half the time. The Colorado Trail had way more solitude after the first 100 miles, and the trail towns like Salida were way more hiker-friendly. The ability to just start walking without a lottery win made the whole trip feel more free. For a long distance hike, the vibe and logistics of the CT made the experience way better for me. Anyone else done both and have a strong preference on which trail gives a better overall experience?
