There is so much fun to be had in Weston-super-Mare that you might never want to leave, but if you're an adventurous soul who enjoys daytrips, why not try the following:
Cheddar Gorge is a mere half-hour drive away and really is a spectacular place that you'll remember forever. An area with cliff top walks tops the gorges, and underneath there are plenty of caves. Why not also visit the lookout tower? The views here are simply astounding, but if that's not exciting enough for you, why don't you go explore the caves in detail or participate in Cheddar Gorge X-Treme? - rock climbing, caving, down deep and dirty or up high on the cliff walks - with graded climbs and caving expeditions, this is an experience suitable for many. You can also combine both into a day package and return to your holiday home exhausted and happy.
Here's another one for the children, and again, only half an hour away - why not visit Bristol Zoo and their over-400 species in 12 acres of gardens and animal houses. There are even 12 animatronic dinosaurs and something fascinating for the older kids - a rope climbing experience called ZooRopia, complete with grown-up safety harnesses. This is a brilliant day out for your entire family!
With just a short drive you could also get to a good number of semi-local museums in Wales - the Cardiff Story Museum, the National Museum Cardiff, the Museum of Welsh Life in Cardiff, and even Newport Museum. Or you might prefer Bridgwater's Blake Museum, or even the privately owned Oakham Treasures Museum, full of memorabilia from times gone by (mainly the twentieth century) from consumer goods to tractors and farm items. They even have a large Wurlitzer and some new Wallis and Gromit pieces.
And perhaps you might like to take the 23 mile trip inland to Glastonbury. Sitting on the ancient Isle of Avalon, within the Somerset levels, and famous of course for its enormous festival held at Worthy Farm in Pilton, Glastonbury is just as interesting because of its Abbey, the Tor and the delightful village itself. Glastonbury Abbey is a mainly ruined abbey in 36 acres of parkland, reputedly the burial ground of King Arthur, and the holder of the Holy Thorn - the tree sprung from the staff of Joseph of Arimathea. Re-enactments of the medieval life are held throughout the Summer months, giving the visitor a sense of life for the monks in past times.
Glastonbury Tor is a large distinct and powerful landmark which looks out over Wales, Wiltshire, Somerset and Dorset. With a reputation for being "one of the most spiritual sites in the country", it is definitely worth taking a quiet and contemplative tour, whatever your beliefs about its history. Then kick back with some well-brewed ales from Glastonbury Ales. Try Holy Thorn - amber and smooth, celebrating the Thorn's flowering - or Black as yer 'At, a dark chocolate-tasting Winter ale! Glastonbury's town tourist guide or information centre will give you further information including about the Lake Village Museum, the Tor, the Haynes Motor Museum, the Chalice Well, the Show Museum, caves at Wookey Hole, and much more.
