Day 88 - Altitude sickness?

Cusco

K was suffering from something that we think was altitude sickness, a surprise after having avoided it so far, but the symptoms (lack of energy, nausea) and the fact that we'd just come back to Cusco after being at a lower altitude in the Sacred Valley for a few days all seemed to add up.

While K spent the day barely being able to drag herself around, M visited Saksaywaman, an old Inca fortress on the outskirts of  the edge of Cusco that was within walking distance (though the way was pretty much all uphill).

Stone walls with closely fitting stones .... that's gotta be Inca work

K was feeling a bit better, so we walked to San Blas again and had a nice lunch in the sun in the courtyard of a lovely cafe, then had what M thought was perhaps the best fun of the whole trip so far with a spot of souvenir shopping.
