There are some layout problems on an iPhone. The header background image isn't visible, same with each header section, so you only see the transparent overlay on a grey background, which is very hard to read (css opacity problem?). All internal or external links after each numbered item are offscreen, far to the right, as are many of the menu items at the top of the screen.
Aside from that, it looks good, and having comments from other local bloggers or organisations is a really nice touch. Otherwise though it seems a little empty of real value? Many items don't have any description, and those that do it is only a sentence or two, and the images all appear to be used elsewhere. Perhaps a smaller number with deeper content would work better? As it is, if I was using it as a guide because I was interested in staying in Cornwall, I would be forced to Google most of the items. The items where you have provided links to find out more (eg Tintagel Castle) work better, at least you are controlling where the customer goes off site, rather than just setting them loose on Google.
All IMHO of course.
