Ujung Karang Tinggi is a Maratua slope-to-wall reef with rich coral.
Ujung Karang Tinggi is a Maratua reef that starts as a gentle slope and then drops into a steeper wall. It suits intermediate divers who want a coral-heavy line with macro hiding places and the chance of bigger fish passing in the blue. The site rewards a slow pace and a clean turn so you can use both the slope and wall sections well.
Safety Notes
Plan the wall section conservatively and keep an eye on gas if you follow the slope deeper.
Access Restrictions
Best for divers comfortable with wall profiles and deeper turn points.
Legal Notes
Use normal Maratua boat-diving logistics and follow operator guidance for the slope-to-wall line.
Community notes to help plan your visit.
Scuba Diving
Best for steady divers who want a slope-to-wall profile and a long, deliberate pace. The site rewards a controlled descent and a tidy turn more than aggressive depth chasing.
Freediving
Not a casual freedive target because the wall drops quickly and the site is better handled on scuba.
Snorkeling
The shallow slope may be visible from the surface, but the wall is primarily a scuba profile.
