Sandrine's most unforgettable dive experience was in Indonesia, where she had the opportunity to dive with a school of over 40 majestic mobula rays.
Diving in Halmahera was excellent. We spent 4 full days diving Halmahera from a liveaboard and we got excellent visibility (over 80 feet) the whole time and saw many large schools of jacks, barracuda and friendly batfish. The reefs were extremely healthy with lots of soft and hard corals and were filled with fish life like anthias.
We also did not see any other dive boat the whole week on our Halmahera trip, a very nice change from other more popular diving destinations in Indonesia where it can get quite crowded.
