In reply to LukeBR:
Sport and trad at Utby just East of the city.
Some sport crag 30 mins south that I forget the name of.
Bohuslan is just over an hour North of the city and is excellent, mostly classic trad but some sport too.
Worth taking a trad rack but you don't need much specialist gear - a full set of cams and wires and usual extenders, even just a single rope.
