Beautiful but pricey. The first cave is huge and worth the visit. The museum is tiny. The second cave and "quest" is simply a short walk through a smaller cave. The tower and hike are for the views.
Try out The Black Dog saloon bar. Just opened. Very friendly staff, reasonably priced beer & amazing interior design. Will be serving food in here very soon.
Town is very touristy & the caves are expensive at £17.50 per adult, though one can revisit within the next 10 years to visit parts of the attraction not seen the first time, so keep the ticket safe
Don't park in the marked bays, park on the grassy rocky area. They can only legally charge you in the linedbays. (Done this for the last 8 years without fail, or paying a parking fee)
