It’s worth visiting Gozo, if only for this incredible boat trip experience! I’ve just travelled in a small, open vessel along a natural tunnel which cuts through the cliff face here on the west coast of this small Maltese island. My boat trip started at what’s termed the inland sea. It’s a small shale and pebble beach set around a lagoon of tidal water. This pool is circled by high, crumbling yellow cliffs on two sides.
