I can assure you that despite my utterly inadequate photography skills, the gardens are definitely worth a visit. They’re still in really good shape, despite the long hot summer. And the artwork on display is always interesting and beautifully sitatuated, even if it’s not always to your taste. Definitely worth a visit.
The only trouble is the distance to travel. If you’re near southampton, it’s great, but unfortunately it’s a 2 hour drive from Brighton. Along that deservedly hated road, the A27.
