The table below lists, from East to West, the access points, landmarks and other special features along our part of the coast which all members of CG-Service should be familiar with.
The path on the cliff-top along most of our part of the coast is maintained by an organisation called the ''Heritage Coast''. Their members know the area extremely well and have always been very cooperative. A key for all the Heritage Coast gates should be in each landrover.

Something to think about: if the earth turns underneath the moon once every 24 hours, and high tide is due to the moon attracting the water in the sea, why are there two high tides per day, i.e why is the water high on the opposite side of the earth from the moon as well?When the sun and the moon are 'pulling in the same direction', High Water is especially high and Low Water especially low; in practice these spring-tides occur two days after a full or a new moon, i.e. about every 14 days. The opposite are neap-tides: half-way between two spring tides, High Water is less high and Low Water less low. The highest spring tides occur in spring and in autumn, when the earth is closest to the sun.
It is important to keep in mind how quickly the water level changes at certain times between High and Low Water: fastest when it is half-way up or down. The Rule of Twelfths states that in the approximately six hours between Low Water and the next High Water (or between High Water and the next Low Water), the water rises (or falls) by 1/12 of the total height difference in the first hour, by 2/12 in the second hour, then by 3/12, 3/12, 2/12, and 1/12 in the remaining hours.
I used to have a table of the times of High Water at Barry on this website, for use at the College. The information came from WXTide32, a convenient Windows port of a Linux program. But having been informed by Miss T J Wenham, the Assistant Copyright Compliance Officer at the UK Hydrographic Office, that using the harmonic constants required by WXTide32 infringes Crown copyright, I have had to remove this service from my page.2nd-year students in CAVRA should in general know the approximate time of the next High Water, especially of course when they are on call-out duty, and perhaps also whether it is spring- or neap-tides. Note that tides are also especially high when the wind is blowing from the West.
