Please submit any useful information about climbing Craig yr Allt that may be useful to other climbers. Consider things such as access and accommodation at the base of Craig yr Allt, as well as the logistics of climbing to the summit.
Unlike the Garth mountain, which is more popular, the Craig yr Allt is nowhere near as easy to access. It is advisable for one to find/take a train to Taffs Well Train Station, and ask locals the easiest route from there.
The climb is steeper than the Garth, and along the top it is 'narrower' and somewhat some 'eerie.'
