Where can we lock up 4 expensive bicycles securely while visiting the garden?

I would recommend calling them to ask. I didn't notice a bike area.

Don't bring your bikes. They own very nice bikes that they will let you use for a small fee. They are electric bikes ment only for bigger kids. At least 13.

There is only car parking that I saw there are several places to park but some are paid some are not but didn't see anywhere you could lock up bikes.
