Дайв-сайты: Eastern Province

Batticaloa is located on Sri Lanka's east coast, about six hours' drive from Colombo or three hours from Trincomalee. A small domestic airport has occasional flights from Colombo. Dive infrastructure is still developing, with only two or three operators offering regular trips as of recent years. Most are run by local fishermen-turned-guides who know the reef locations intimately. Equipment standards vary, so experienced divers may prefer to bring their own regulators and computers. Accommodation ranges from basic guesthouses to a handful of mid-range hotels in Batticaloa town.

Whale shark sightings along the east coast are most frequent from March through May, coinciding with the northeast monsoon's waning and the onset of calmer seas. The sharks follow plankton blooms that develop as surface waters warm. Sightings are not as reliable as at established whale shark destinations like the Maldives or Mozambique, but local fishermen report encounters throughout the season and the numbers appear to be increasing as monitoring improves. Most encounters are snorkelling-based from boats, though divers occasionally meet them on the reef when conditions align.

The civil conflict in Sri Lanka's eastern and northern provinces ended in 2009 and Batticaloa has been peaceful and open to tourism for over fifteen years. The area is safe for visitors and local infrastructure is steadily improving. There are no unexploded ordnance concerns at established dive sites. The Sri Lankan Navy occasionally conducts patrols offshore but these do not interfere with recreational diving. As with any emerging destination, it is wise to dive with a reputable local operator who knows the current conditions and maintains communication with coastal authorities.

Due to the depth of the wreck, with the deck at approximately 47 metres and the seabed at 54 metres, the HMS Hermes is classified as a technical dive. A minimum of Advanced Open Water with Deep Specialty is needed to visit the superstructure at 38 metres, but exploring the flight deck and deeper sections requires technical diving certification such as TDI Extended Range or equivalent, along with experience in decompression diving. Most operators require a minimum of 50 logged dives.

Limited penetration of the superstructure is possible for certified technical divers with appropriate training and equipment. However, the wreck is a protected war grave under Sri Lankan maritime law, and removal of artefacts is strictly prohibited. Most recreational divers explore the exterior of the superstructure and flight deck, which offers abundant photographic opportunities. The wreck sits upright, which makes orientation relatively straightforward.
