Without breakfast, we travelled to a beach to remove trash and plastic from it. We walked up and down the beach removing trash from the shoreline. After 30 minutes we took a break and were told about anchialine pools. They are little tide pools on the shore where there are usually animals. Unfortunately, sand built up after a tsunami. We dug the sand out of the pool and used it to build sandcastles. Next, we went to a hike about an hour north of the beach. We went down to a black sand beach and went in a rope swing. We walked along the rocky shoreline and saw a rusty and abandoned tank from World War II. As we were coming back, we stopped at a fruit stand and smoothie stand. I got a scoop of chocolate ice cream. Then we came back and had chicken for dinner.
