Grassy Slope by the Walls. The broad grassy slope below the enclosure, with the church and the old walls lining the crest. Even with visitors, the hilltop keeps a deep calm: wind, birds and the faint sound of the rivers far below. Jvari is about 20 km north of Tbilisi, an easy half-day trip that pairs naturally with a walk through Mtskheta’s old streets.
