Can I swim in the underground pond at Nil Diya Pokuna?

Swimming in the Nil Diya Pokuna underground pool is allowed, but it should only be tried by confident swimmers, with an experienced local guide beside them. The water looks crystal-clear, yet it is unusually cold, and the depth feels safely shallow until it is not.

Even if plunging into the immaculate blue water is a highlight for many, keeping safe is still the priority. There is no real ambient light, so you depend on head torches completely, and the pool has sharp rocks under the surface. Local guides often bring safety ropes too; they are vital to staying orientated in the absolute dark.
