Welcome To the Trevithick Trail

Skip to main content


Apart from the early drover’s paths, transport links from Merthyr Tydfil to the coast have nestled together closely following the line of the River Taff along the valley bottom. The Glamorgan Canal from Merthyr to Cardiff was completed in 1798 and the Merthyr or Penydarren Tramroad (along the route now largely followed by the Trevithick Trail) was completed in 1802 with the trains of wagons loaded with iron hauled by horses.

The first railway to be constructed was Brunel’s Taff Vale Railway built mainly to the east of the river reached Merthyr Tydfil in 1841 and still remains in use today. A second line mainly to the west of the river was built jointly by the GWR and Rhymney Railway companies and was opened in 1886 but closed in 1951 to passengers and entirely in 1954. The first main road from Merthyr to Cardiff also ran along the valley bottom through Troedyrhiw and Merthyr Vale. The section of the present A470 dual carriageway from Merthyr to Abercynon was constructed to a large extent along the route of the Glamorgan Canal and the former GWR/Rhymney Railway line.

As a result, access to the Trevithick Trail by public transport is very easy with almost adjacent access from the railway stations at Edwardsville (Quakers Yard) and Merthyr Vale and access within a couple of hundred yards from Abercynon, Troedyrhiw, Pentrebach and Merthyr Stations. Bus services running along the A4054 road between Merthyr Tydfil and Treharris give even better access to the trail and the local service operated by Mintax actually operates along a short section of the trail in Troedyrhiw.
