The Tallinn Botanic Gardens (Tallinna Botaanikaaed) lie a little over six miles outside of Tallinn’s city center in the quiet and picturesque valley of River Pirita. The gardens cover an area of 123 hectares that face the river and are surrounded by lush woodland.

The gardens boast 8,000 species of plants throughout a series of large modern greenhouses along a 2.5-mile (4-kilometer) trail. You will find displays of tropical, subtropical and desert plants, from Estonia and abroad, in specialized exhibits that change almost every month. One of the highlights is the rose garden, although you should visit in late spring or summer to see it at its best.
