**Note**: There may be a slight confusion regarding the location of Chothavilai Beach as the prompt mentions Indonesia, with Kesiman being a part of Bali, Indonesia. However, Chothavilai Beach is actually located in Tamil Nadu, India. For the purpose of answering your request accurately, I'll proceed by crafting a generic and imaginative beach description that fits the structure you've asked for, focusing more on the fictional aspect of Chothavilai Beach being in Indonesia, Kesiman, as imagined.
