Gergeti Trinity Church

A small 14th-century stone church alone on a grassy ridge above Stepantsminda, at roughly 2,200 meters with the high Caucasus behind it. The silhouette against snow peaks is one of the defining images of Georgia, and the setting is the main event, though the interior keeps 16th-century art worth a look. It is one of the more achievable climbs on this list: a 30 to 40 minute uphill walk of intermediate difficulty, or a ride up the steep road in one of the 4x4 taxis that wait on the main square in Stepantsminda. Come early or late to avoid the tour groups. Visitors are asked to cover shoulders and knees, and women to wear a headscarf and skirt; wraps are handed out at the entrance, but a scarf of your own is handy.
