Section 2 – Porth Trwyn (Llanfaethlu) to Cemaes
Crossing of outlet of Cemlyn lagoon (SH329 935)

This beach is accessible apart from up to an hour either side of high tide. The inland alternative is a convenient walk up a lane to St Patrick’s church.
Section 4 – Amlwch Port to Moelfre
Traeth Dulas (SH478 884)
As this is an estuary access is available apart from about an hour either side of high tide. However it should be remembered that the tide does come in very quickly.
Section 5 – Moelfre to Pentraeth
Porth yr Aber (SH512858)
Benllech – around Benllech Isaf Café (on joining Ffordd Cynlas) (SH522 827)

The short section of shore at Red Wharf Bay, just before joining the sea wall is accessible apart from at high tide, on tidal ranges above 30ft / 9 metres.
The Lleiniog to Fryars Bay section is accessible apart from up to an hour either side of high tide, but remember it is about 2km in length so you’ll need to allow ½ an hour.
Section 7 – Beaumaris to Menai Bridge / Llanfairpwll
