Well you have St Michaels Mount, which is always a good spot for photos, Mousehole for the postcard harbour shots, Lizard itself for the wild south coast and plenty of scope nearby for prehistoric monuments, ruined tin mines, sweeping rugged moors and bird thronged cliffs. Incidentally, you'll be in sunny Cornwall, not Devon! Don't want to upset the locals! Sinnejohn was in this neck of the woods recently, so I'm sure he will have some hands on suggestions too. Penzance itself is a bit bland and metropolitan, but the villages nearby are much more picturesque.
The Lizard is a haven for exceptional plants and flowers and a coastline dotted with little fishing harbours and gorgeous sandy bays fringed with rare rock formations and caves; perfect for your next outdoor adventure!
