With some awesome day trip options in the surrounding area, renting a car makes sense. Without one, it’d be much harder to explore all that Zagreb, 35 miles away, has to offer. Jarun should be toward the top of your list here. Zagreb Zoo and Arena Zagreb are awesome attractions too. The locals will also probably point you toward Novi Vinodolski, 40 miles away. If you can only see one attraction here, let it be Novi Vinodolski Beach. (But we’d also recommend Frankopan Castle and Church of Saint Philip and Jacob.)
