Entry ticket per person is 5k from the gate, 50k for snorkeling & swimming bundled with Underwater photograph & 35k for the bridge crossing.
Additional fees are 4k for taking a shower, 2k for changing, 5k for ojek ride to the beach (you can walk for free, it’s around 5-10 mins).
Food is relatively cheap, 150k for a portion of 5 people.
Recommended to find time off-season to snorkel and enjoy the beach, remember to bring a wetsuit along with GLOVES, the corals are sharp, and the sea is shallow, YOU WILL GET CUTS IF YOU SWIM WITH NORMAL CLOTHES.
