On the second day, immerse yourself in the rich biodiversity of Twin Lakes of Balinsasayao. Start your day with a bird-watching session, as the lakes are home to a variety of bird species. You can spot colorful birds like the Philippine eagle, hornbills, and kingfishers. After bird-watching, you can go for a nature walk around the lakes, exploring the lush forests and spotting other wildlife such as monkeys, wild boars, and deer. If you're lucky, you might even catch a glimpse of the elusive Philippine tarsier, one of the world's smallest primates. In the afternoon, you can take a refreshing swim in the crystal-clear waters of Lake Balinsasayao or enjoy a picnic by the lakeside.
