Most facilities in Makarska itself are along the traffic-free beach strip, Šetalište Dr Franje Tuđmana (map).
The Old Town (map) is small but well-preserved, stretching back from the harbour through alleys and piazzas, especially pleasant at dusk. The main church of Sv Marka (map) has a baroque interior.
Malacological Museum (map) is the grand name for this collection of sea-shells. Worth looking in for the venue, an old Franciscan monastery south end of the centre.
Vepric (map) or “Lourdes Makarska” is a woodland grotto with shrine. The mountains rearing up behind Makarska comprise Biokovo Nature Park (map), stretching 36 km along the coast and 9 km inland. It’s a huge landscape of limestone karst crags, cliffs and ravines but the most accessible part is the village of Kotišina (map).
Hiking: the mountains behind town have several hiking trails, scenic and seldom crowded (alltrails.com). Don’t leave the trails as pitfalls abound. The snakes are mostly innocuous but don’t mess with the horned / sand viper (Vipera ammodytes).
