Further along Tran Phu beyond Mulberry Beach, a pretty but rough road winds up the hillside to some old French field guns. There are six of these massive cannons, all with support trenches, demonstrating how strategically important Cap St Jacques was to the colonial authorities as it guarded the waterways to Saigon. Look out for Hem 444 in the fishing village, about 8km from Vung Tau, and turn right on a small track.
