Penzance is the most westerly major town in Cornwall, enjoying a mild microclimate that allows subtropical plants to thrive in Morrab Gardens. The harbour and promenade offer views across Mount's Bay to St Michael's Mount, accessible by causeway at low tide. The neighbouring village of Newlyn has been home to an important art colony since the 1880s. Penzance serves as a base for exploring West Cornwall and the Isles of Scilly, reachable by ferry or helicopter.
