If you have to visit one crag on Krk, go to Portafortuna. If you have to visit three, go to Portafortuna three times. Manageable approach, nice summer climate, good equipment, lots of easy and epic routes, view and ... well, what more do you want from easy-going, vacation crag? A restaurant next to parking? 30-meter overhangs with jugs? Sheep, that baaa your beta from the top of the wall?
