I see the huge value of this experience. Combining walking with talking is something I often experienced to be very effective for deep conversations. You don't keep eye contact but nevertheless you are very close. For some topics it helps to just talk without having to look someone in the eye. Long pauses are not a problem because there is the landscape passing by that removes the awkwardness. Also walking in a slow pace occupies a part of your mind and gives you the opportunity to communicate and think even better. I don't remember the reason for it but I think it was related to subconsciousness. I also made the experience that biking and talking also works very well as long as the road you are taking is broad and empty enough. Traveling by bike also makes it more simple to carry on some luggage and to cover more distance between stays.
