1. Ynys Llanddwyn, off Ynys Môn/Anglesey

There’s much more to this volcanic tidal island besides its fame as the home of St Dwynwen, patron saint of lovers. Wander across the sandy beach from the densely wooded Newborough Forest and you’ll join a 1½-mile circular path around the island that takes in all its many highlights.

The first stop is at the bare ruins of a church – all that is left of a mediaeval Benedictine Abbey that once flourished here. Further on, at the isle’s southern tip, sit two small lighthouses, Tŵr Bach (‘Little Tower’) and Tŵr Mawr (‘Big Tower’). The latter is remarkably photogenic, having been modelled on the windmills that were once common on Anglesey. Nearby stands a terrace of neat little pilots’ cottages, where you’ll find an exhibition about the island (open most days in summer). The small cannon outside summoned the crew to the lifeboat that was once stationed here.

Pause a while here to soak up some gorgeous views of Snowdonia. Do also look out for Soay sheep, wild ponies, and roseate, Arctic and little terns. Come in spring and you can witness the spectacle of a huge colony of cormorants taking over the islet of Ynys yr Adar (‘Bird Rock’).
