I'm really pleased to hear that my recent addition 'The Desolation of Smaug!) in Twll Mawr
http://www.ukclimbing.com/logbook/c.php?i=316559 is being enjoyed. It looks like all the hard work bolting it was worthwhile, and it's getting the attention it deserves, it's also been great to read about some of the ascents on various blogs...

A number of climbers have contacted me through UKC to find out how to access Twll Mawr....
With a spare rope it's possible to abseil in from the top of 'Supermassive Black Hole' (Bolt, Thread and Fence?)This is just over the fence from the Bus Stop - Nant Peris track. Bolt and thread can be found on the right hand side of the obvious central fin adjacent to the fence.
To access Twll Mawr on foot, walk from Bus Stop Quarry car park along the track until it dips down next to Dali's Hole and the 2 gates, hop over the gate on the right as if heading downhill towards the Rainbow Slab. Very soon and after descending just a few metres a flat area / plateau on the left can be seen. Follow this level which leads directly under the 'Peregrine Walls'. A round blast shelter and 2 mounds of slate rubble mark the way. When some large Boulders and a leaning ruined shelter are reached another flat area opens up with the Golgotha Slab behind. The Twll Mawr access tunnel can be found less than 50 metres away from these Boulders.
