Different with
Gong Cave or
Tabuhan Cave that has structure is dominated by beauty, Luweng Jaran is a underground river line, so it has the entrance like river. This Cave a swallow hole, in the other words, a place where river dissappear from the surface. This cave is also known as Labirin Cave because it has a lot of branching and leveled paths
Although this cave hasn't opened for public yet, this cave has already become a "heaven" for climber and explorer because this cave serves a great beauty and miracles. The cave's wall is naturally ornamented by underground rock like reliefs, Stalactite and Stalagmite hanging with various beauty, looks like human, animals, tower and small version of grand canyon that are very charming.
On the cave's floor was formed a small lake from clear water's drop that we can see through the floor's lake. The sound of dropping water rhythmically heard together with wind sound that leak into the cave.
One of the alley on the west chamber was constructed by ruined of big rock. Peoples need to duck between fissures. And in one area, there are one small alley where we need to creep to pass trough.
There are tools that need to be brought along in this vertical cave exploring; Kernmantle rope, Anti-friction, Cover all, Helmet, Headlamp, Boot, Webbing and Carabiner, SRT (single rope Technique) set that consists of Chest and sit Harness , Millon Rapide , Descender, Ascender, Cow's tail, Foot loop and Medical Kit.
The first Entrance of down climbing can be used for only one rope' line because it is very small entrance. A few meters downside, we can smell karts rock, the humidity of underground, and the surrounding that become darker. In one point, there are path to south where we need to duck walking because of a lot of hanging stalagmite. Around 30 m to the south there will be a dark room with 30 m wide, it looks like an underground station decorated naturally with underground rock.
This is the second point around 25 m downward, that make us realized how big this cave is. On this point, it has 3 alleys, from east, south, and West. The line toward 25km length is the South alley.
There is small river flowing where various caves animal live, such as shrimps and small fishes with their transparent body and some arthropod such as spiders and crickets, The river flow become bigger and oxygen become thinner downward, so oxygen tube is needed here.
