Definitely - there's some awesome easy to medium stuff there.

Red Arete is the classic climb in the area, 3 pitches (can be done in less) of bolted grade 15ish - you could always lead them and have your brother follow up. Its nice and friendly and just a neat location, have been up there a few times. Its obvious from the road when you go past Unwin Lodge before the village - just follow some tracks into the bluffs at the base of Sebastopol and scramble up a track through the scree/scrub. Red Arete climb is pretty self-descriptive, the one to the left is called shark attack and is a little harder (17?), especially the top pitch!

Also apparently there's a line of single pitch climbs by the poo pond, which are suitable for top roping though I never got round to climbing them. Grades 16-17?

Annabel could probably tell you more :)
