Tonotan Guns and Caves
Tonotan
Japanese coastal guns and a tunnel network cut into the hillside on Weno's west coast; the guns still point at the lagoon entrance and are listed on the US National Register of Historic Places
During WWII the Japanese cut tunnels and gun positions into the hillside at Tonotan on Weno's west coast, installing coastal defence guns to control shipping channels in the lagoon. Many guns still sit at the cave mouths, and visitors can walk a short way into the tunnels with a torch, overlooking the lagoon and airfield. The site is on private land, so a local guide is required, along with a small entrance fee. The hiking path is short but steep and slippery in the rainy season, making it suitable for a half-day land tour of WWII sites.
