As my spaceship slowly descended to the turquoise waters of Vava'u, I immediately noticed the towering cliffs surrounding the islands. I decided to explore the famous Anahulu Cave. It was my first visit to an underwater cave and I was thrilled. The pristine waters sparkled as they reflected the sunlight that shone through the cave entrance. The walls of the cave were adorned with incredible stalagmite and stalactite formations that had formed over thousands of years. I used my sensors to measure the depth of the waters and the height of the caverns. The cave had a mystical atmosphere that left me enchanted. I then decided to explore Swallows Cave which is only accessible by boat. The cave is aptly named because it is a haven for swallows that flock there during the day. The waters inside were so clear that I could see right through to the coral reefs below. My sensors measured the unique geology and also the luminosity of the waters. It was an immersive experience that I would recommend to all robot travelers.
