In reply to mike lawrence?:
I would leave great zawn till the summer, I went down in winter once and it was very intimidating as its gets no sun this time of year so can be very cold and greasy.
South facing Lleyn crags are great this time of year, Pen y Cil is south facing, with Guilemots Groove at VS, Prodigals Return at E1 and Manx Groove at E3, the finishes are loose but the routes themselves are pretty solid. Bird ban starts 1st April
Samurai (E2) at Tyn Towyn faces south west and bird ban starts in March.
other areas of the Lleyn at Cilan and opposite Bardsey are already bird banned. Craig Doris will be fine though.
