@YK1001 This place is located in the eastern province, Sri Lanka. from the international airport, it will take about 6 hours. it’s good for people who travel eastern province, Sri Lanka. also, you can come to this place by seaplane (seaplane will land in Passikudah beach). but again you need 20-minute drive to this place.
the corals are not far from the port. approximately 250 meters or you can get a boat and visit some other different coral places.
there is a hotel with beach access and other than that you will not find any. so we have to go 15-minute drive to get some food. I’m sure you will not feel hungry after seeing this coral reef and fishes 
ha ha ha haa
another important thing is, you can not catch color fishes and damage corals in any coral reefs in Sri Lanka. but you can catch fishes in some other areas. in Sri Lanka there are many people exporting color fishes, shrimps to other countries
