Around 7km west of the park entrance, the only accommodation close to the park is OK but could do with some sprucing up. The bungalows have poor mattresses but are otherwise fine; hot water comes in a bucket from the kitchen. The real reason to stay here is to enable you to get to the park at dawn.
There's a simple restaurant (lunch/dinner Ar20,000/35,000); they prefer advance notice if you plan to eat here.
