I'm enjoying this discussion because I sometimes wonder how this comes across to my guests. We're a little over a mile from downtown Mystic, where the shops, restaurants (Mystic Pizza), bascule bridge, etc. are. This is no biggie for me; as a matter of fact, I get cranky if I don't have time to walk to downtown and have to bring my car and try to park. I understand, however, that plenty of guests aren't necessarily willing or able to walk into town, so I give the approximate distance and label it "walkable," since it IS walkable for some people, but not for others. There aren't sidewalks for about a third of the route, but it's a spectacular ramble along the river and through the historic district and many guests who are runners, walkers and/or nature lovers have enjoyed it. I think I had a couple of reviews that said it was "too far" to walk and one who complained about the lack of sidewalks, but that's about it.
Nothing to do with walking, but I'm always surprised that I don't get more kayakers. The boat launch is just down the road and people who travel with their 'yaks could drive there in a minute flat.
