During low tide, we were able to walk out onto the beach and look at the coral, clams, and sea cucumbers, and we did a fair amount of snorkeling in addition to our walks. The beauty that surrounded us was overwhelming.
I went with two friends out to a place called “Shark Island” on our last day in Koh Phi Phi. At low tide, you could often see small sharks.
It so happens that low tide also brings you closer to the other animals that don’t appreciate being stepped on. As we approached Shark Island, I got too close to the rock and stood up, lost my balance, and slapped a nearby sea urchin silly. Unfortunately for me, sea urchin spines are like needles, and I ended up spending the rest of the night trying to pull out 13+ brittle spines from my hand.
