Good walks from and around Bryn Teg
Moel Siabod
This is the obvious mountain walk from Bryn Teg as you can walk straight out onto the path from Dolwyddelan described on this page, which was edited by Nick Fletcher on the basis of his numerous ascents.
Cwm Idwal
This is a wonderful shortish walk with some clambering. Going further up Twll Ddu leads to an exciting high level walk to the Glyderau and Tryfan.
Cwm Penamman
Cwn Penamman is the hanging valley directly opposite Bryn Teg; here is an excellent afternoon stroll around it.
