We went to villa de Leyva and liked it so much….we went back. A great little town with hiking right out your door. Enjoyed an opera in the town square one evening. I could spend a lot of time there for sure.Hey I am going to make another suggestion.
If you can swing it go to Villa de Leyva. Some of the most awesome fossils found in this hemisphere there. I bought a piece of coprolite there and had some excellent trout too. Very nice little village, at least when I was there in 2008.
I was going to also suggest a dip in the mud volcano, its pretty awesome. You have already passed it though.
