The most popular approach to Herm is from the west through the well marked 'Alligande Passage'.
Plot a course, allowing for tide, to a point approximately 100m north of Alligande beacon (green post topped with orange A). This passage passes through two groups of rocks - Petit Creux to the north and Alligande to the south. Keeping a little closer to Alligande , follow the transit 074
0 that puts Vermerette (yellow beacon topped with orange V) in line with the white patch on the end of the Herm Harbour wall.
Pass to the north of Vermerette beacon to bring the leading lights in line on an approximate transit of 078
0. In daylight the leading lights are two large white drums approximately 25m and 100m in from the shore.
