[6] The 11.5 miles (18.5 km) length of coast path through Bridgend County Borough was officially opened on 17 October 2013.

The path then travels through Cardiff Bay, along the coastline to the River Usk which requires going inland along the river to the bridge at Newport[9] and further on to Newport Wetlands National Nature Reserve (with more than 100,000 birds), on the banks of the Severn Estuary, which has the second highest tidal range in the world at 15 metres (49 feet).

It ends at Chepstow where it meets the 177-mile (285 km) Offa’s Dyke Path, alongside the Anglo Welsh border, linking the Severn estuary with the Irish Sea at Prestatyn.

[10] In addition to the Glamorgan Heritage Coast, the path takes in three national nature reserves: Kenfig Pool & Dunes (Bridgend), (Merthyr Mawr Warren) Bridgend, and Newport Wetlands (Newport).

It also passes through three Heritage Landscapes: Merthyr Mawr and Kenfig Margam Burrows (which stretches from Neath Port Talbot through Bridgend to Vale of Glamorgan), Caldicot and Wentloog Levels (Cardiff, Newport, Monmouthshire), and Lower Wye Valley (Monmouthshire).
