The Underwater Observatory is situated 6 meters below sea level at the bottom of the White Tower which is accessed through a 100 meter bridge. A tunnel joins the two underwater halls, one of which observes the surrounding corals in the underwater reef known as the "Japanese Gardens" while the other gazes at clambering corals and schools of fish, deep into the sun dappled waters of the Red Sea. The visitor can stand here for hours watching the scene which changes from window to window, by day hour and by the season of the year.

A living coral reef has been constructed around the observatories and, since the Underwater Marine Park does not feed the creatures in the wild, this constructed reef provides a natural habitat which attracts many different kinds of coral-nurtured marine creatures - and the creatures which feed of them.

After a visit to the sea bed, the Tower Bar on the entrance level offers a welcome break for coffee, cake, pizza etc. For the adventurous, a 90 stair climb provides access to the Lookout Terrace on the top of the tower and its view of four countries.

An elevator in the Tower allows access to the Underwater Observatory rooms for the disabled.
