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.
