Allowing people to walk under water wearing an open-ended helmet, the Marine Walk has become a popular activity in Bali. An air horse connects the helmet to a scuba tank, for the supply of air. A defogging mechanism was used when creating the interior of the helmet, preventing the front window part from fogging. This walk lets you admire the beauty of a sea garden, marvelling at colourful corals and fish, whilst also hand feeding them. Marine Walk is available at Lembongan Island. A popular choice among those in search of Bali luxury villas is Alila Villas Uluwatu. Reputed for its distinctively attractive design and location, it offers some of the most desirable Bali resort villas.
