The Trevithick Trail in Merthyr Tydfil follows the route taken by Richard Trevithick's steam locomotive on its first journey on 21st February 1804.
The Cornish engineer was asked by Samuel Homfray, owner of the Penydarren Ironworks, to produce a steam engine to haul the iron from his works.
The route from Penydarren to Abercynon is 9 miles long.
Alongside stunning scenery, public art celebrating Merthyr Tydfil's heritage can be seen along the route.
In the nineteenth century Merthyr Tydfil was the iron capital of the world. Richard Trevithick initially built the steam engine to drive a hammer at the Penydarren Iron works in 1802. The engine was then mounted on wheels to become a locomotive.
The locomotive's first journey took place because of a bet between Homfray and the rival ironmaster at the Cyfarthfa works, Richard Crawshay.
The iron was to be taken from the Penydarren works to the Navigation at Abercynon where it then joined the Glamorgan Canal.
The nine and three quarter mile journey, hauling ten tons of iron and 70 men took over four hours. It was the first journey to haul a load by steam locomotive.

Merthyr Tydfil Council launched the trail to coincide with the bi-centenary of the locomotive's first trip in 1804. From 2004 to 2008 work to complete phase two of the trail was undertaken. This included implementing a variety of landscaping improvements along the trail and the installation of public art and trail markers along the way. The trail was officially opened in June 2008.
The Glamorgan Gates project has coordinated the production of artwork along the trail. A joint venture between University of Glamorgan and Communities First, the artwork has been produced with the involvement of numerous local community groups.
The trail runs down the Taff Vale, alongside the River Taff offering the chance to see plentiful wildlife, flora and fauna.
It follows the line of the tramroad and walkers and cyclists following the trail will pass by several sites of historical interest including the sites of former ironworks, the Trevithick tunnel and the Taff Vale viaduct.
