Rabat has fine Baroque churches, St Paul’s and St Agatha’s Catacombs and the Roman Villa. There are many interesting walks within close proximity to the town, such as the Chadwick Lake, Dingli Cliffs and Verdala Castle overlooking Buskett Gardens, the only wooded area in Malta. On the southwest shore is the Blue Grotto where, legend reports, sirens bewitched seafarers with their songs. Four caves reflect the brilliant colors of the corals and minerals in the limestone. The most spectacular is the Blue Grotto itself, which is best viewed in the early morning with a calm sea. Buses run to an embarkation point in Valletta where a boat can be taken to the caves.
