Llanddwyn is a popular spot due to the outstanding natural
beauty of the beaches and forest.
Approach
From Caernarfon, follow channel to C1/C2 then head directly for S
Cardinal buoy off south-west corner. (From Holyhead, pass 1 cable
south of buoy). Turn when light tower bears north. Approach
anchorage 50 metre off southern Prong and anchor in 5 metres SW of
awash rocky patch, or inshore of patch close by Mermaid Cove. To
anchor in Mermaid Cove enter mid-channel leaving Ynys-y-Clochedd to
starboard and anchor in 1.8 m. in centre of pool. Dangers
In fresh to strong onshore winds, it is inadvisable to attempt to
cross Caernarfon Bar. Rock (awash) 2 cables east of Pilot’s Cove
(marked occas. by S. Cardinal). Two rocks (awash) south of islet off
Mermaid Cove. Shelter
Pilots Cove and Mermaids Cove are sheltered from west through north
to north-east. A swell makes them uncomfortable in strong
south-westerly winds. Fair to good holding on mud and sand.
