Superb access, sounds and sights.
This review is especially helpful for those who have or use the following: Powerchair
The gardens offer something for all the senses - including taste and touch of spices on the spice trail. Flat access, mostly smooth trails and smooth paving apart from deep in the woods. I've visited a few times as the place covers a large distance - literally miles.
Transport & Parking
We parked near Kew Road - walk to the gate on the opposite side of the garden wall as it is is horrifically bumpy. My brain nearly fell out. Alternatively we have parked at the rear garden entrance where there was plenty of accessible parking on a first come first served basis (rocks and compacted dirt surface). Parking I believe is now free in their carpark for blue badge holders.
We were caught out visiting this year on a date when there was a night event on - and the park shut extra early! Their web site is not clear on this. The only inaccessible part is the underground aquarium - but be prepared for long walks and the heat of the tropical houses can get to pass out levels. The tree canopy walk way is not clear on weight restrictions for powerchairs so I didn't chance it. Terrain is undulating around the rockery area and in the woods. Carers go in free, I had a discount - but once we both got in free!
Wheelchair accessible toilets around the park. They have a Changing Places toilet (called adult changing facility) near their carpark gate entrance at the back of the park. (See picture). It looks like a portacabin.
No problems - no real interaction.
Anything else you wish to tell us?
The tropical houses played a role in my power chair motor overheating and blowing up when I was their! You might need to be aware of the humidity and heat if you go on a hot day. However, on a cold day this will keep you warm!
