Neptune's Finger is a marine park site with a vertical wall beside the largest sandfall in the park. The reef begins shallow and drops steeply into deep water, for a profile from 9 to 34 m (30 to 110 ft), with a ray cleaning station and frequent turtles and groupers.

The dive

The dive begins on the shallow reef at around 9 m (30 ft), over a sandy bottom. From there the reef drops steeply into deep water along a vertical wall, which reaches 34 m (110 ft) at the deep end of the profile.

Beside the wall runs the largest sandfall in the marine park, where sand spills over the edge into deeper water. The reef has a ray cleaning station, and turtles and groupers are frequent sightings; schools of mobula rays sometimes pass as well. The site is rated intermediate to advanced.
