Alona House Reef is a boat-access dive site located in Panglao, Bohol, roughly 700 metres (less than 1 km) from the shore at a bearing of around 83–88°, reachable in approximately 3 minutes by boat. Because of the short transit, divers are advised to gear up at the pier before departing so they can enter the water immediately on arrival.
The reef begins as a slope starting at around 5 metres (15 feet) and transitions into a wall that descends to 25 metres (80 feet), below which the terrain becomes less interesting. The seabed is mostly sandy with large coral formations, and the wall itself is covered with many different coral species. Crevasses throughout the structure provide hiding places for eels, and the site is well suited to both daytime and night diving.
The reef holds a solid range of macro subjects: giant frogfish are frequently sighted, and Harlequin ghost pipefish and Mushroom ghost pipefish inhabit the sloped wall. Sea cucumbers, feathered starfish, nudibranchs, eels, and tropical fish schooling through the corals round out the life visible on a typical dive. Macro photography is particularly recommended here, and nitrox diving is considered a good option for the site.
Visibility is generally good to excellent, varying with tide and weather conditions, and the water temperature sits between 26–30°C year-round in a protected exposure. Currents are light. The site is accessible to beginner certified divers seeking a relaxed dive, though care should be taken not to touch the corals where critters are living.
