Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The Relitto Toikosan Maru rests inverted off Acireale's coast, within the Timpa Nature Reserve. This significant historical wreck presents itself dramatically upside down; its massive propeller and rudder now face skyward, forming the initial focal points for divers.
Approaching the site, which requires a roughly 20-minute dinghy ride, divers descend along an anchor chain. A steep drop-off follows the anchor chain, leading to a maximum depth of 38 meters. Exploring the ship's structure provides ample photographic opportunities due to its colonization by various marine organisms.
During the second part of the dive, following the ship's side, experienced divers can undertake a limited penetration of approximately 15 meters into the wreck, safely proceeding from one light source to another. Navigating this interior passage reveals intimate spaces where marine life takes shelter.

Dive Experience & Conditions
Diving the Toikosan Maru begins with a boat entry, followed by a 20-minute dinghy journey to the wreck. Upon arrival, the initial descent follows an anchor chain, dropping to about 6 m (20 ft) before the seabed plunges deeper. Below, the inverted wreck becomes discernible from depths between 20-25 meters. Visibility in the Mediterranean generally remains good, though conditions can vary. Inside the wreck, a torch becomes essential for illuminating the 15-meter penetration route, where groupers and shrimp may be observed. Due to the maximum depth of 38 meters and the wreck environment, divers need an Advanced Open Water certification and at least nine logged dives, including a deep specialty patent.
Dive Difficulty & Safety Guidelines
Exploring the Toikosan Maru wreck demands adherence to specific safety protocols and certification requirements. All divers must possess an Advanced Open Water certification, a deep specialty patent, and a minimum of nine logged dives to participate in guided expeditions. The site, being a historical wreck, necessitates special permits, which are managed by Jonio Pro-Dive Catania. These 'Nulla Osta' from the Superintendence for Cultural and Environmental Heritage of the Sea and the Port Authority of Catania ensure authorized and safe access. Adhering to the guide-to-diver ratio, typically a maximum of 5 divers per guide, is also paramount for controlled navigation within and around the wreck, particularly during any penetrations.
