What is your exact overall Bali itinerary. Nothing down south.
We go to Amed every year for diving/snorkeling/chillaxing.
Depends what you want to do. Plenty of free diving places around Jemeluk. Do you want to hire any gear like a free diving buoy etc.
Plenty of people free dive in Jemeluk bay. Can free dive anywhere off the beach.
Local free diving places will arrange trips to USAT Liberty in Tulamben or tag along with a local dive centre.
There are freediving shops at Amed and also at Tulamben. We just left today and they guys were out nearly every day. Unless you are travelling alone, you can just go and dive at Tulamben. We just had a couple from Hawaii in the room next door to us and they were freediving on the wreck, coral gardens and drop-off for a couple of days and loved it.
If you need a buddy, probably best to contact them and ask.
