Besides kayaking, we’ve been doing some trekking here. Today’s hike was through a deep limestone cave, through which two different streams run. Thousands of bats, dozens of cave crickets, several large spiders, a few cave toads, and water deeper than our heads. At some points, I had to swim with one hand, trying to keep my other hand above the water (in that hand were: my [non-waterproof] flashlight, and our drybag, which held our [non-waterproof] camera.)
Definitely one of our trip highlights.
