the minotaur trail is bloody great.
there’s an additional descent you can sneak in, if you/she thinks that’s a good idea.
after about 4 or 5k, you cross the river, it’s a nice bridge, in a nice gorge, very nice.
once you’re back on the gravel road, the blue trail turns right, effectively heading back to the start. but if you’re both keen you can turn left, and climb up the forest road (round a hairpin) for about 5 mins, and look out for the red-fox (Cwflym Coch – or something) trail on the right, the start is a little sketchy for a blue-route rider, but after that short section, it’s good old fashioned swoopy singletrack back down to the valley, great fun!
(if you’re keen for even more after that, you can turn left at the end of the singletrack descent described above, up a steep gravel road. it does ease off, but it keeps going for about 10 mins – to another awesome red-fox descent)
