Time of day
Park opens 07:00/08:00 depending on season (check) and closes at dusk; the first 3 h after opening on a weekday are the window, before the sea breeze builds by 11:00 and the airfield wakes. No night access.

What will you hear?
Little tern colonies screaming over the pans, stilts and avocets yelping, redshank and Kentish plover, reed warblers in the Dragonja channel; salt-worker rakes and the sea beyond the dyke.

No night access; the closed areas are only visited on the park's 3-hour birdwatching programme (max 12). Škocjanski zatok (Koper): DOPPS reserve with hides, free.
Cost: Sečovlje Salina €7 adult April–Oct, €6 Nov–March (2026); Škocjanski zatok free.

Who runs access
- Sečovlje Salina Nature Park – birdwatching with an expert (park authority) — 3-hour guided programme into the closed pans, max 12 people.
Field-recording notes
The pans sit between the Portorož airfield (light aircraft in summer), the coast road and the Croatian border crossing at Sečovlje — work early on a weekday. The Adriatic sea breeze builds by 11:00. Colonies of little tern and Kentish plover are roped off; stay on dykes. The park is fenced with fixed opening hours, so no night access — book the 3-hour birdwatching programme (max 12) for the closed areas. Salt harvest June–September adds human sound that is itself worth recording.
