Open GardensGardens you can visit

Well, it was once someone's garden! It was the childhood home of Lady Jane Grey, and a favourite place to ride and hunt for Henry VIII and Elizabeth I.
A beautiful country park with many ancient trees, wild deer, upland areas, and a tearoom.
Don't miss it if in Leicestershire.

A wonderful example of an alpine garden, we visit regularly

An interesting lakeside garden created by John Ruskin and his descendents. Dante's ascent from purgatory, a physic garden, fern collection, alpine walk and many more areas to explore. Strange and compelling, with stunning views. Cafe.

Went a couple of years ago in July. The island beds were amazing, and it shows how big some grasses can grow. There is a lot to amuse as well as the gardens there are trains, if you like that sort of thing. I spent my day in the gardens and found it instructive. I also went to the nursery, the plants were reasonably priced but not all you see in the gardens are available. There was a water centre but I did not visit. Would say its worth the visit if your that way but not as varied as a day out at Barnsdale.
