Might be visiting here soon; Kammer's helpful notes don't mention the parking (sounds a great walk but difficult with 3 kids and none-stoney wife!), but I see Moth has spent time here too. Is parking straightforward?
Also looking at visiting the Mynach Falls nearby; do you know anything of this? Find some nice pics online, but info is lacking.
Many thanks
Tim
PS - Other sources have the site only spelt with one 't'; I couldn't find it on TMA, then thought that odd as the book has it in, so did a browser search and found it that way. P300 of the book has a sketch of Julian's using just one 't' (though he goes for the double t in the text); maybe worth adding as a variant spelling?
