The summit of the mountain has a mosque that is still used by Muslims. It also has a Greek Orthodox chapel, constructed in 1934 on the ruins of a 16th-century church, that is not open to the public. The chapel encloses the rock which is considered to be the source for the biblical Tablets of Stone. At the summit also is "Moses' cave", where Moses was said to have waited to receive the Ten Commandments.

Mount Sinai's rocks were formed in the late stage of the Arabian-Nubian Shield's (ANS) evolution. Mount Sinai displays a ring complex that consists of alkaline granites intruded into diverse rock types, including volcanics. The granites range in composition from syenogranite to alkali feldspar granite. The volcanic rocks are alkaline to peralkaline and they are represented by subaerial flows and eruptions and subvolcanic porphyry. Generally, the nature of the exposed rocks in Mount Sinai indicates that they originated from differing depths.

Located just 15 km south of Taba, the Fjord is a spectacular diving spot housed by a stunningly beautiful and protected bay with dazzling coral reefs and unforgettable scenery. If you’re an experienced diver, you’ll be tempted by the “Fjord hole”: a site you will reach after following a huge coral bed at 16 m of depth, you’ll find a huge hole that goes down to a depth of 24 m. After entering the hole, you’ll witness an amazing marine life scene: fish from the open sea coming to feed on plenty of tiny Glass Fish and Silver Fish.

The “Fjord Banana” is an alternative for the less experienced divers: a shallow reef in the shape of a banana, reaching a maximal depth of 12 m, and housing a wide variety of fish and corals.
