Distance from Glasgow: 50.5 miles
Lat & Long: N56.039604 W-5.293683
Tides: Tide tables
Site entry/exit: Walk through the gap in the Bushes as in the picture below and down the rocks to enter the water.
Underwater directions: head straight down to 22m and turn right until you come to the wall. Wall runs down to about 36m where it turns into a boulder slope we stopped at 40m. There is a nice big mushroom anchor and chain that hangs over the wall at about 25m.
Site Hazards: Can be a long swim back to shore if following it all the way down. Entry and exit can be tricky if there is a bit of a swell. If there is a flood or ebb tide you have to work hard to stay on the reef.
