Batumi’s Botanical Garden, 8km northeast of town at Mtsvane Kontskhi (Green Cape), is well worth a trip. With many semitropical and foreign species, the 1.13-sq-km gardens cover a hillside rising straight out of the sea. It takes about 1½ hours to walk the main path at a leisurely pace.
You can get there by marshrutka 15, from Rustaveli and Gogebashvili, or 31 from Gogebashvili east of Chavchavadze.
