At the moment there's a roadwork/construction so Make sure you come to the right access. Walk along Jeoryeong-ro (road) which stretches along the rear of the village. You'll find one of few entrances there. When you see the ocean, that's where the entrance is.
Definetly worth a visit in Busan. It offers stunning views on sunset with many choices of backgrounds. It also has many spots built specifically for taking photos. It has many souvenir shops with unique goods and many cafe with seats facing the sunset. The whole track is well decorated.

It's overall a wonderful tourist site, which offers different Korean experience from Seoul city.
