My alarm was set for 4 am but thanks to my lack of sleep I just couldn't face getting up for sunrise, and I turned it off almost involuntarily, before quickly disappearing back into unconsciousness. Woke up again at 8 feeling slightly guilty for not making the most of day, but not too guilty, and made a quick escape back to Waterfall Country to do the Four Falls Walk I didn't have the time to do previously.
There were already a handful of people about when I arrived at the Cwm Porth car park, it was a Saturday, so I wanted to get started before the crowds arrived. Shortly after setting off, I took a short detour down to where those who have a penchant for potholing can access one of the entrances to the River Mellte as it thunders through an underground passageway, to get a few pictures of a rather fetching woodland scene.
