Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Originally a Bulgarian trawler built in 1964, the Pioner was intentionally submerged in July 2008 to create an artificial reef off Saint Ivan Island. This purposeful sinking established a new, complex habitat for marine organisms and an accessible dive site for enthusiasts.
Resting upright on a seabed of sand and rocky patches at a maximum depth of 18 m (59 ft), the wreck measures 22.5 m long and 5.5 m wide. Its relatively shallow position and sheltered location from north-easterly winds contribute significantly to its popularity. For certified Open Water Divers, exploring the Pioner presents an excellent opportunity to experience wreck diving without extreme depth challenges.
Divers can navigate the exterior, observing how different species have colonized its hull and superstructure. Those with appropriate training and experience can also consider limited penetration dives to observe its interior structure, revealing another layer of its purpose as a sunken vessel.
