Our offering of free tours will end on Saturday 28 September 2024 and will re-launch again in 2025. Thank you to everyone to joined our tours in 2024!

General information

Tours are free to the public without prior booking, though the maximum group size will be 15 and you may be asked to come back another at a later time if the group is full.

Please see our Visit page for information on transportation, parking and accessibility.

Please note that under 18s must be accompanied by an adult and that dogs are not permitted in the glasshouses so unfortunately the tours are not dog-friendly.
