One ticket is enough for Dashawan and Sumawan, 30 in the off-season and 60 in the peak season. You don't need to walk by yourself after you enter, but it costs 5 yuan for a person to take the sightseeing bus, and the amusement facilities also cost money, that is, walking on the sea, cycling on the sea and speedboats. If you swim, the locker room costs money, and you can take a bath. One person is probably 10 yuan.
It is recommended to go swimming in Suma Bay and take the seaside plank road from Dashawan. The scenery is very good and there is a suspension bridge.
Have fun!
