Best garden toys?

[feedmenow]

I have an 11 yo, 8 yo and 18 mth old and want to get some stuff for them for the garden.

We have a sandpit and paddling pool and a ride on dumper truck.

But I'm trying to think of something that they will all get some use out of! Like a mini trampoline with handle, or a swing set.

What outdoor toys do your kids actually play with and what have they got bored with within no time at all?

climbing frame with more challenging stuff, eg climbing wall, trapeze rings, monkey bars would be well used

DS (6) a bit bored of swing/slide but has discovered skateboarding down the slide
