Our tour guide was Tola. I think there were about 18 people in total. I was the only Japanese person; most of the others were from English-speaking countries or countries where English is spoken fluently. I can speak some English, but I thought it might be a bit difficult for those who aren't confident in their English. All explanations were, of course, in English. Also, regarding whether to take the boat through the mangroves, it was asked if anyone traveling alone wanted to go, so if I hadn't raised my hand then, I don't think I would have been able to ride. There was one other person traveling alone who wanted to ride, so the two of us went together. It apparently costs 11 dollars for two people. Only four participants rode the boat, but I'm glad I did. At first, I thought, "Is it really worth it just to go through the mangroves? Maybe I didn't need to ride." But the best part was getting close to where people live on the water. Before that, we walked around the town a bit, but it felt insufficient as we quickly looked around together as a group. So, it was great to be able to get close by boat. The people who didn't ride the boat apparently waited, sitting in front of the same souvenir shop, for about 30 minutes while we were on the boat. Tola's guide was easy to understand, and I learned many new things, which was great. He also offered to take photos for us. Thank you very much :)
