Diving atLighthouse (Cambodia)
Currents often dictate the experience at sites like Lighthouse, a prominent feature in Cambodia's diving landscape. Divers may encounter moderate to stiff breezes and opposing tides, particularly in shallower areas. These dynamic water movements sculpt the underwater environment and challenge even experienced divers, requiring strong finning and precise buoyancy control. Understanding these fluid dynamics is crucial for planning an effective and enjoyable dive.
As evening covers Lighthouse, the local air temperature is measured at 30°C. The current wave height at the surface is recorded at 0.2 m. These late-day readings characterize the surface conditions for the night.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Diving Cambodia's underwater realm, especially around sites such as Lighthouse, presents a compelling combination of natural beauty and historical intrigue. Beyond the living reefs, the seabed holds secrets of past voyages, with archaeological evidence sometimes found in the form of scattered pieces of 400-year-old porcelain.
These artifacts, remnants from an old Chinese wreck, provide a tangible glimpse into the region's rich maritime trade history. Divers frequently encounter vibrant coral reefs, some dropping to depths of around 20 m (66 ft), which provide critical habitat. These formations foster a wealth of diverse invertebrate communities that populate their intricate structures, from colorful nudibranchs to hidden crabs.
While sightings of larger pelagic predators are not consistently reported, the ecosystems themselves provide endless interest; the sheer diversity of smaller reef inhabitants creates a dynamic, engaging environment. Crucially, local conservation groups actively work to preserve these underwater habitats.
Their ongoing initiatives support reef health and contribute to the resilience of the marine environment, aiming to ensure these fascinating sites remain vibrant for future generations of divers.

Dive Experience & Conditions
The typical depth profile at sites in this region like Lighthouse ranges from shallow 2 m (7 ft) areas, often under dive boats, to vibrant coral reefs descending to around 20 m (66 ft). Divers should prepare for variable visibility, which has been reported to be in the range of 3-6 m (10-20 ft) depending on specific conditions. Water temperatures remain generally warm throughout the year, characteristic of tropical Southeast Asian waters, making a 3mm wetsuit or shorty often sufficient. Moderate currents and surface swell are common, particularly in exposed areas, adding a challenging element to the dive and requiring good physical fitness and advanced buoyancy control.
Dive Difficulty & Safety Guidelines
Diving around sites like Lighthouse demands a keen awareness of your surroundings and strong diving skills. Maintaining excellent buoyancy control is crucial to avoid contact with the reef and potential hazards like urchin spines. Divers should be mindful of exposed infrastructure, such as jetties or submerged debris, which can present physical risks like cuts or scrapes. While generally safe, the presence of litter can be an issue in some areas, necessitating vigilance. It's advisable for divers to carry a basic first-aid kit, including items for minor injuries and repairs, especially when exploring less-developed areas away from direct tourist infrastructure.
