Why the bay is its own sea
Boka is nearly enclosed, deep, and fed by karst springs including submarine ones that push cold fresh water up from the seabed. Three consequences a swimmer notices:
- Cold patches. You swim through a band of genuinely cold water for a few metres and out again. That is a spring below you. It is startling and harmless.
- Less salt, so less buoyancy. People assume they have got worse at floating.
- Clarity drops after rain, when the mountains dump run-off straight into the bay.
Against that, the sheltered inner bays are among the warmest water in the country in August, because the water sits still and shallow and has nowhere to mix.
Swim off concrete, not sand
The local pattern is a stone or concrete platform with a ladder into deep, clear water — often outside a café, usually free, sometimes with a few sunbeds. This is what the promenades of Dobrota, Prčanj and Herceg Novi are made of, and it is better swimming than any of the coastal beaches.
Named places
| Where | What it is |
|---|---|
| Dobrota promenade | Kilometres of ladders into deep clear water, minutes from Kotor |
| Prčanj and Stoliv | Western shore, quiet, the bay at its most reflective |
| Ljuta | Cold spring water meeting the sea, restaurants over the water |
| Morinj | Small beach, very cold spring outflow, and the best fish restaurants in the bay |
| Žanjice | Outside the narrows on Luštica — white pebble, open sea, clearest water |
| Mirište and Rose | Luštica peninsula, reached by boat or a rough road |
| Plavi Horizonti | Actual sand, on the Luštica outer coast, shallow and warm |
The narrows
Verige, where the bay pinches to 340 metres, is the reason the whole thing exists as a sheltered basin. Chains were strung across it to block enemy ships — hence the name, which means chains. The current runs noticeably there and swimming across is a bad idea with the ferry crossing every few minutes.
Practical
- Water shoes. Concrete platforms have sea urchins on the steps and the ladders are slippery.
- The inner bay is warmest in late August, the outer coast clearest all season.
- Jellyfish appear occasionally in late summer in the inner bay, where the water does not flush.
- Boats. The bay is busy with traffic in August — swim near the shore, not across channels.
The one nobody mentions
Swimming in the bay at seven in the morning, before the boats start and while the water is glass and the mountains are still in shadow, is the single best thing about staying in Boka rather than on the coast. It is free, it is empty, and it lasts about an hour.
