Slovenia
A short Adriatic coast where about 150 resident bottlenose dolphins live in the Gulf of Trieste. We share the story only.
Story only, for now. We love learning about this place and its ocean, so we share its story here and do not sell trips yet. Checked by Ocean Calling on 6 Oct 2026. Sources: Dolphin watching guidelines - Morigenos, Slovenian Marine Mammal Society; Dolphins - Slovenian Environment Agency (ARSO) environmental indicators; Morigenos - activities and services.
Why: Slovenia's short coast has a year-round community of common bottlenose dolphins, and the researchers at Morigenos in Piran have studied them since 2002 and photo-identified about 130 animals. The dolphins are protected under the EU Habitats Directive and Slovenian law, and the Morigenos guidelines ask boats to keep at least 100 m away, travel slowly and parallel, stay no longer than 15 minutes, and never chase, feed, swim with or touch the dolphins. We follow those rules and would only ever watch alongside the researchers.
🧭 Travel advice, checked 30 Sep 2026. The US State Department rates Slovenia at Level 1, exercise normal precautions, as of 15 May 2026. Smartraveller also advises normal safety precautions, and mentions petty crime and alpine hazards such as avalanches and flash floods.

Why Slovenia
Slovenia has only 46 km of sea, but it holds a resident group of about 150 bottlenose dolphins, studied by a local research group for more than 20 years. They are seen all year, feeding, resting and raising young. The rule from the researchers is to stay 100 m away, with no swimming and no feeding. We offer no trips here.
Conservation-led. Ocean Calling guests never chase, touch or bait animals.
