I rode my bike for half an hour from Nha Trang city to the pier, exchanged tickets at the counter, and boarded the boat at 8:30 (with a large tour group). I first went to Orchid Island. The island has a large hinterland with elephants, deer feeding, ostriches, goose racing (bet 30,000), a butterfly garden, jet skis, etc. Walk straight from the goose race track into the trail and climb for half an hour to reach the waterfall. There are restaurants and beverage shops on the island, and the boat leaves for Monkey Island at 1 o'clock. I originally bought separate tickets so that I could take a boat directly between the two islands without having to go back to the mainland and take another boat out to sea.
