How much is the entrance ticket price for foreign tourists at Peradeniya Gardens?

The entrance ticket price for foreign adults who visit the Peradeniya Botanical Gardens is now 3,000 Sri Lankan Rupees (LKR), whereas foreign children pay 1,500 LKR.

These set rates do get small revisions by the Department of National Botanic Gardens, so it is wise to carry a little extra local cash. Also, unlike many other tourist places in Sri Lanka, you can buy the tickets straight at the designated counter for visitors at the main gate, no need to pre-book online beforehand.
