Britain's largest rhododendron and azalea gardens are part of this 70-acre garden just north of the city center. An impressive Chinese garden has the largest collection of wild-origin Chinese plants outside China. There's a cafeteria, a visitor center with exhibits exploring biodiversity, and a fabulous gift shop selling plants, books, and gifts. Handsome 18th-century Inverleith House hosts art exhibitions. Don't miss the soaring palms in the glass-domed Temperate House and the steamy Tropical Palm House. The hilly rock garden and stream are magical on a sunny day. Guided tours are available. Take a taxi to the garden, or ride Bus 27 from Princes Street or Bus 23 from Hanover Street. To make the 20-minute walk from the New Town, take Dundas Street (the continuation of Hanover Street) and turn left at the clock tower onto Inverleith Row.
