Going on a stag do to Split. Any must see sights or things to do? Worth hiring a bike?

Some riding brac (Island a ferry ride away) but prob not worth taking the bike for(they do rent them). Some good diving.
DO get a ferry to HVAR and party, works off the hangover with the horrendous climb up to the castle the next day. Have a wonder around diocles’ palace. Ive not spent a huge amount of time in split (we go to bol on Brac) but it’s a nice place. Make sure you visit the islands.

Yeah definitely going to Bol and Hvar. Might even rent a motorbike and go for a wee tour.

They rent quads in bol (brac). Supetar is bigger but not as nice. It’s not a stag type place though; far too quiet. I’d suggest a day in bol (there’s a ferry point), then off to hvar for the evening.

Diocletian’s Palace is a ‘must see’ in Split. Pretty hard to miss, actually! It’s huge…
