House of Marbles constitutes a full day out. I wouldn't recommend a long drive specifically to sample what this attraction offers unless you're a marble buff (it houses the largest collection in the world). For us, it's just two miles from home, an easy cycle ride, and is a a place where a couple of hours can be whiled away quite pleasantly even on a rainy day. There's also no admission charge which is alway a bonus! It is essentially a large gift shop with knobs and whistles, a glass blowing studio, displays and interactive exhibits. I'll keep mum about how the giant spider may be enticed to move down its web.
