Site Overview

Split Apple Arch is one of the signature dive sites of Vavaʻu Group (Northern Islands – Cavern Capital) in Tonga. Split Apple Arch is a majestic underwater archway in Vavaʻu at 12 to 20 m, with big-eye trevally, barracuda and swirling glassfish and soft corals - a favourite of wide-angle photographers. The site reaches a maximum depth of about 20 m, with an average depth near 15 m, and its arch and wall topography is draped in rock and coral. Marine life is the headline attraction, with bigeye trevally, great barracuda, glassfish, soft coral, moray eel, butterflyfish regularly recorded here, drawn in by the moderate currents and the rich South Pacific productivity of the region. Visibility typically ranges from 22 to 40 m, while water temperatures hold a consistent 24 to 28°C year-round, comfortable in a 3 to 5 mm wetsuit. Conditions suit intermediate divers, and with the right guide the site delivers both the drama of its arch and wall and intimate encounters with the smaller residents. Local operators run regular trips from Neiafu, and the protected, low-tourism setting keeps coral cover dense and fish life abundant, making Split Apple Arch a genuine standout on any Tonga itinerary. Divers who time their visit to the calm season will find the most predictable conditions, though the site rewards repeat visits across the year.

Dive Briefing

"The dive at Split Apple Arch begins with a thorough operator briefing covering the site layout, expected marine life and emergency procedures, followed by a controlled entry and a short transfer from Neiafu. Descending toward the arch and wall profile, divers are immediately surrounded by bigeye trevally, great barracuda, glassfish, soft coral, moray eel, butterflyfish, with the reef and structure revealing more detail the closer you look. The maximum depth reaches about 20 m while the average sits near 15 m, so a dive computer and disciplined gas planning keep the profile safe and comfortable. Currents are described as moderate, and the guide chooses the entry time to make the most of slack or mild flow, using a reef hook or DSMB when needed. Neutral buoyancy protects the fragile coral and the group stays close to manage depth and any surge. The safety stop is completed in open water on a DSMB, and the boat follows the bubbles to collect divers at the exit point for a relaxed return to base. Split Apple Arch is best dived on a mild current when the underwater archway frames big-eye trevally, barracuda and swirling glassfish. A morning dive gives the clearest water, and a controlled descent places you at the arch quickly. Water stays 24 to 28°C, and a 3 to 5 mm wetsuit is ample. A torch and DSMB help with the recesses."
