Easy access on the Portsmouth Road, on site parking is limited.
Entry for non members is a tenner.
Food in the cafe is reasonably priced and is ok. See photos.
Kids enjoyed the egg hunt, although not well attended.
Going around took around forty minutes or so. Muddy so take your wellies on a wet day.
Clive of India is listed as a famous name at Claremont, a man who was the cause of over a million deaths through famine in India???? and the cafe lists a Clive of India Curry!!!!

Visited this place expecting a variety of different experiences to see and large space,
instead a small park like pond and small hill!
worst was being harassed for membership which i did not need, i visit NT places about once a year .

This is a National Trust park that, as its name suggests, is more about the gardens than any historical buildings. I'm not sure if the Belvedere in the photo is ever open, but it wasn't when we were there (early March). There didn't seem to be a lot of formal planting but the carpets of daffodils were beautiful and there are a lot of rhododendrons which must be spectacular at bloom time. Although we visited on Mother's Day, the gardens didn't feel crowded and we were able to get a seat inside the small cafe (there is a lot of outdoor seating which must be pleasant in summer). The food was good, mostly sandwiches but there were a few hot dishes which looked tasty. We managed to get a parking spot even though the car park looked full; we got there around 11 and I'm sure parking would be problematic a bit later in the day. We had young kids with us and they really enjoyed the small thatched cottage, a single room filled with toys and games and dressing up clothes. There is also (separately) a children's play area, fairly limited (climbing frame with slide and a small "house"). We climbed the hill which gave views across the lake and was good for photos. There were mostly water birds on the lake and jackdaws on the grass; I heard a few parakeets and lots of robins but didn't see any unusual birds. Overall, a lovely spot to hang out for a couple of hours with family or friends, and plenty of flat areas for pushchairs and wheelchairs.

Lovely walk around the lake, beautiful daffodils. We were able to take the dog which made it very special.
However - beware of the bacon rolls in the café. They are microwaved, bacon was hardly cooked and the whole thing was a soggy mess. Very disappointed. Come on National Trust - they used to be freshly cooked.
