My partner and I visited Monet's Garden last Sunday, 18 April 2010. I suffer from arthritis and have a mobility problem and find standing difficult. We arrived about 10am and already there was a very long queue to get in. Fortunately there are benches to sit on just across the road from the entrance. I sat down whilst my partner queued to get in.
Due to my disabilty we were charged for one entrance and he went free as a carer. There are steps both up and down at the entrance, so for anybody in a wheelchair would find it impossible. Having said that, there may be a separate entrance, but I didn't see one.
There are steps to get into the house and two narrow steep staircases to get to the first floor. Within the garden the pathways are suitable for wheelchair users. Due to the gardens being extensive I wasn't able to walk all around, but I enjoyed what I did see. My partner went and took photos of the places I couldn't walk to whilst I sat on a bench. The flowers and the colours were stunning.
After about half an hour the place had become very crowded, so would recommend arriving early. During the summer months I would imagine it to be extremely busy.
A thoroughly enjoyable visit and the surrounding area is also very pretty. I would recommend anyone to go, especially if they are interested in art and/or gardens.
