I was hoping to see Moth and/or Jane's answer to this question.

Oh well, here's mine:

Looking back, it was a rock arty year for me.

I became one of the volunteers on the CSI: Rombalds Moor rock art recording project, which should keep me busy for the next year.

On these Isles, I eventually got to see Ormaig at the third attempt at trying. Even then, my luck was in as there were a lot of logging operations going on in the area and even at Ormaig itself the trees were coming down.

I must confess, I've fallen in love with the American Southwest; its deserts, canyons, mountains and wilderness. This year, amongst many sites visited, I got to the cliff dwellings of Mesa Verde and the pueblos of Chaco Canyon. However, my "best site visited in 2011", without doubt, is the rock art within Horseshoe Canyon. It took careful planning to get to, as the rim of the canyon is a 30 mile drive on a sand road across the San Rafael Desert, the floor is 830 feet below the rim and the main panel of rock art, the Great Gallery, is a 6.5 mile round trip along the bottom of the canyon.
