The Welsh 3000's are the mountains in Wales with a height of 3000ft or more above sea level. All fifteen are located in the Snowdonia National Park in North Wales. Their close proximity makes it possible to walk all fifteen in 24 hours, a strenuous walk known as the Welsh 3000s Challenge. The figures below are the Ordnance Survey spot heights and rounded up to the nearest feet. If you spot any mistakes or out of date figures due to re-surveying let me know. The ticks indicate which ones I have bagged.
