I stayed here two nights while visiting MRNP. It was an absolutely beautiful location, about 10-15 minutes away from the Sunrise Entrance. The first night, I got there after 9pm and there were still plenty of spots available. I found a spot right next to the river. There were a few other people, but everyone was very quiet. You could see the lights and hear the cars driving on the main road, but they eventually stopped. The second night, I managed to find a spot tucked super far in that had a small private beach. It was farther from the road so you couldn't see or hear anything. I didn't see anyone else the whole afternoon/night. Highly recommend!!
