Confirm these fees before you book so your operator plan and day budget match what you will pay onsite.
Budget separately for national-park admission, island transport, organized diving, and any Croatian individual-diving authorization. There is no separate Mljet marine-park scuba tag documented in the reviewed sources. The park visitor ticket does not replace diving permission or operator compliance.
A live-pricing conflict exists for 2026. The park's official PDF lists adult admission at EUR 25 in June-September and EUR 15 in October-December, while the official Parkovi Hrvatske webshop displayed EUR 30 and EUR 20 for those periods on September 5, 2026. Verify the price shown at official checkout and retain the receipt.

| Where to pay |
The two official 2026 sources conflict. Use the amount presented by the official checkout for the chosen date or confirm with the park. Standard inclusion is described as one return St Mary Island boat, listed inland visitor services, marked routes, parking at Vrbovica, and visitor insurance. One-day admission is published with a 25 percent reduction after 4 pm, subject to operating hours. |
| Additional St Mary Island Return Boat | EUR 5 One additional return trip | Visitors taking an extra boat trip beyond the included return journey | Mljet National Park sales point or current official channel | Confirm the final departure and whether the extra service operates on the visit date. |
| Croatian Individual Diving Authorization | EUR 318.53 One year from issue | Divers conducting individual rather than organized recreational diving in Croatian waters | A Croatian Harbourmaster office or branch office; appointment recommended | Organized dives through a registered Croatian dive center follow a different legal path. Individual divers must also check no-individual-diving zones and mark the area with a compliant buoy or recognized diver flag. The authorization does not override national-park prohibitions or cultural-heritage restrictions. |
| Organized Scuba Diving | Operator quote Per dive, package, course, or private arrangement | Most visiting recreational divers | Registered local dive operator, such as the Pomena-based center | Ask what the price includes: boat, guide, tank, weights, park or harbor fees, rental equipment, computer, torch, insurance, pickup, and tax. No public separate Mljet diver tag was confirmed in the reviewed official sources. |

Check the booking invoice and request proof of registration rather than paying an unsolicited third-party link. |
