Diving and Snorkeling
The entire east coast is known for its fascinating diving and snorkeling sites, see Amed - Dive Sites of Bali. The villages between Amed and Banyuning host a number of dive centres that offer diving courses, trips to the various sites as well as equipment, also for snorkelers. The Baliku Dive Resort and White Sand Divers are at close distance to the villa, but don't be afraid to try out those that are further off because most provide a free transfer service from/to the accomodation. Find out about more centres over the internet and take your pick before you leave so that you can enjoy those precious holiday moments right from the start.
The Amed coast comprises many small and large bays, often with sandy beaches and always with a public access. As mentioned earlier, you can also snorkel at the reef in front of the villa. In any case, please avoid the sea during windy and stormy weather and do not go alone without anyone's knowledge. The currents can sometimes be unpredictable -- and you most certainly want to get back to where you started from!
