Fodor's Expert Review Royal Botanic Garden Edinburgh
Explore Britain's largest rhododendron and azalea gardens at this beautiful 70-acre botanical garden. Founded in 1670 as a physic garden, it now has a range of natural highlights such as soaring palms in the glass-domed Temperate House and the steamy Tropical Palm House, an extensive Chinese garden, and a pretty rock garden and stream. There's a visitor center with exhibits on biodiversity, a fabulous gift shop selling plants, books, and gifts, and two cafeterias. The handsome 18th-century Inverleith House hosts art exhibitions.
It's free to roam the gardens, though it costs extra for greenhouse admission, and you can splash out even more for guided garden walks and private tours. It takes 20 minutes to walk to the garden from Princes Street, or you can take a bus.
