climbed in paklenica last may. did not need any trad gear. lots and lots of bolts. but never climbed harder than 6c. all the long routes have bolts. i'd bring a couple long slings to make the belays a bit more comfy. and definitely a helmet. the south walk off from the big crag sucks. always go north to the gully and head down. cost money to get into the park everyday and we had some rain days. didnt climb in split so don't know. double ropes are nice if you have them for some rappels.
