Bok Walk Gorge
The name Bog Walk is derived from the Spanish words Boca de Agua which means water's mouth. It is not known when the Spaniards entered this area of the island though they had an active involvement up to the time of the conquest of the Island in 1655. During the 1660s, after the British occupation, the Bog Walk Gorge or Rio Cobre Gorge was discovered by Carey Helyar.

In 1770 the first road was cut through the Gorge. The first bridge, connecting both sides of the gorge, was of wood but was later replaced by the present structure, the Flat Bridge, which is constructed from cut stone and mortar.
