This collection of traditional, mostly wooden houses, collected from all around Georgia, is spread over a wooded hillside with good views, and makes for an enjoyable visit. The most interesting exhibits are in the lower section (near the entrance), where the buildings are kitted out with traditional furnishings, rugs and utensils, and the attendants can often explain things in English. A Georgian lunch at Rachasubani is a nice idea while you're here.
You can walk up to the museum through large, verdant Vake Park (reachable by bus 61 from Tavisuplebis moedani or northbound on Rustaveli), or stay on the bus until the petrol station 200m past the large Iranian embassy, then walk or take a taxi 1.4km up the road opposite.
