I like to be outdoors most of the time on vacation, preferably long-distance trekking on trails that are new to me. Part of the point of this is to get into a meditative state, so I like the trails to be well signposted so that I'm not stressed by having to navigate, and I like to walk either on my own or with people who can do the "companionable silence" thing. boxcat is always top of my list. I also particularly like trails that end up or pass through places that have a spiritual significance for me.

For environmental reasons, I prefer trails I can reach by train in a reasonable time (for values of "reasonable" that can include an all-day train and a sleeper train along the way.) That said, there are some trails in the US and in Asia that I'd love to do some time, perhaps combined with a work trip so that I feel less guilty about the CO2 footprint.
