I have done Ambon once and Lembeh twice in February. The weather on all three trips was great, virtually no rain during the day, but it is still theoretically the rainy season in Lembeh. I stayed in Black Sand in Lembeh and Dive into Ambon in Ambon.
I loved both trips , met great people and had some awesome spots , including the little dude in my photo.
They are very different destinations.
In Ambon with DIA , for example you do reef diving one day and muck another day. I far preferred the muck diving , especially under the pier which was amazing.Some of the reef dives were at very best average, but that was where we say the psychadelic. You do three dives a day , so are out all day. I loved this arrangement. The resort was really nice with a big pool, but near a busy road and the food wasn’t anything to write home about. The owner of the dive shop , Kaj, was always around checking that everything was going smoothly. He was incredibly nice and funny and couldn’t do more for us all. The resort was almost full in February, it’s family style dining which I always enjoy.
I preferred the diving in Lembeh , it is all muck diving and on both trips I had amazing luck with spots. Bruce and his wife Fung are the most charming , kind and interesting people you could imagine. Their resort is a gem , the food is wonderful, probably the best dive resort food ever , the cottages big and beautiful facing the bay. In February it is often very very quiet in Lembeh and for some time on both trips I was the only guest.
