tap was rusted shut when I was there last, but if someone is in you might be able to ask for some. The toilets down the road don't have running water taps.

From the gully to halfway along this section this is all very poached, windy and hike a bikey. Then you get over the hump of the hill and it all opens up. Hafren to your right with the first sight of Llyn Clywedog around the corner. Mid-Wales is a beautiful place to be on a sunny day, but bring some big and/or knobbly tyres and a good attitude whatever the weather.

Goes through several cwms so is undulating, but this is one of the most beautiful sections of road I've seen.

Running water for the toilets but no taps so no bottle refill. Understand there is a tap at the bunkhouse to the north.

From either side you've got a steep descent with a big drop off followed by a testing climb that might not be doable with luggage. If there wasn't a gate then maybe. Single track more gradually going up on the north side, possibly a sheep track or a cut by some adventurous cyclists?

Quite a deep ford with some slippery rocks. Take care when crossing by bike
