Before going in, we asked about the accessibility for wheelchairs. It was ok, we were told. Well... forget it! Maybe if it's only the wheelchair but if somebody sits in it, you have a problem. The roads are very steep. The map is very unclear. The people from the garden do not accept any complaints. In our case it was due to the bad weather. They give 2,50 discount for the minusvalidus, the person pushing the wheelchair only benefits in loosing weight. I have suggested to the cashier to try push somebody themselves. Maybe then they will give a correct advice. You have been warned!
