• The Dilumacad Underwater Tunnel: one of the El Nido’s wonders!

The Tunnel was discovered in early 90’s by a japanese diver. Ask from your diving guide to show you the memorial plate placed at one of the entrance! Located at 1.5 mile from El Nido, Dilumacad Island – known as Helicopter Island, because of its chopper like shape-, is pretty famous for its cave dive sites named the Tunnel. This dive is on the North side and there is no mooring there. Due to its situation, this dive should not be attempted when there is a strong North wind.

• The Dilumacad Underwater Tunnel: how is it?

The Dilumacad Tunnel starts at 12 meters depth and is 35 to 40 meters long. It has a few ceiling holes which makes this dive an incredible spectacle.
The entrance is wide enough for two divers to penetrate together and a 15-20 meters tunnel leads to a cavern at the centre. The bottom is sandy where small fish and crabs can be seen. The way out is more narrow and only one diver can exit the 10m tunnel at a time. It will bring you out to a rocky area some 20 meters from the entrance and you may see larger fish here. For advanced divers only!
