42 Walks. The Isle of Anglesey - Ynys Mon, is renowned for its stunning coastal scenery and maritime history. Most of the coastline falls within a designated Area of Outstanding Natural Beauty (AONB) covering nearly one third of Anglesey - the largest in Wales - and including Holyhead Mountain, Anglesey's highest point. In addition North Anglesey, Holyhead Mountain and Aberfraw Bay carry Heritage Coast status. The 42 linked circular walks in this NEW REVISED EDITION explore the beautiful diverse landscape of the AONB and its fascinating history. The routes, which range from a 2.5 mile Copper Mine Trail to a 10.5 mile exploration of Holy Island, are well within the capability of most people. Many routes contain shorter walk options. A key feature is that individual walks can easily be linked with others to provide longer and more challenging day walks if required. They follow public rights of way or permissive paths, and cross Open Access land.
