San Marcos La Laguna is a pretty, small, spiritually oriented pueblo on the banks of Lago Atitlan.  However, those who wish to pursue spiritual matters should come with a pocket full of cash as well.  There are less amenities than in other pueblos (for example, there is no ATM machine here) and accommodation costs a lot more.  I only stayed for one night as I want to get to Xela, get a little settled, and be able to work a bit more than I have been.
