At the end of the park's main popular longer-distance hiking trail (5- to 6-km walk, trailhead 9km from park headquarters), this is a large natural lagoon surrounded by green meadows at low-water times, and forest further back. You get a good, modestly-elevated view from the lodge and surrounding boardwalks, which are on tall stilts. Good for observing water birds and the namesake Siamese crocodiles, an endangered species that looks to be doing well here after being reintroduced years ago. In daytime you'll mostly see crocodile heads and tails cruising through the water, while if you spend the night (see below), they often come out and can be observed from a distance by flashlight. You may be able to hire the lodge staff to take you on a boat ride during the day, or a guided wildlife walk at night if you're staying over.
