Benang Kelambu Upper Falls: Beyond the Curtain

Benang Kelambu is famous. Its name — meaning "mosquito net waterfall" — describes the delicate, curtain-like cascade that falls over a wide rock face covered in thick moss and hanging ferns, creating one of the most photographed natural scenes on Lombok. The main waterfall draws thousands of visitors annually, and the well-maintained trail of steps and paths that leads down from the parking area has made it one of the most accessible waterfalls on the island.

But fame has its limits. The vast majority of visitors to Benang Kelambu visit only the main cascade — they descend the stairs, photograph the curtain waterfall, wade in the shallow pools, and climb back to the parking area. They do not notice, or do not follow, the rough trail that continues beyond the main falls, climbing uphill through increasingly dense jungle toward a second waterfall that is, in many ways, more impressive than the one that draws the crowds.

The upper falls are Benang Kelambu's secret — hidden in plain sight, separated from the tourist waterfall by 20-30 minutes of challenging jungle trail and by the simple fact that most visitors do not know they exist.

### Finding the Start

At the base of the main Benang Kelambu waterfall, the established tourist path ends. Most visitors turn around here, satisfied with the curtain cascade and the moss-covered grotto that make Benang Kelambu distinctive. But if you face the main falls and look to the right (east side), a rough trail continues uphill into the jungle. The trailhead may be partially obscured by vegetation, and there is no signage — this is not an officially maintained tourism trail but an informal path used by guides, researchers, and the occasional adventurous visitor.

A guide is strongly recommended for finding and following this trail. The path is not always distinct, it branches in places where animal trails intersect human paths, and the dense jungle canopy creates a uniform green environment where orientation can be difficult. A guide who knows the upper trail can lead you there efficiently and safely; without one, you risk spending an hour searching for a path you may never find.

### The Ascent

The trail climbs steeply through primary rainforest — the same dense, towering jungle that characterizes central Lombok's mountain slopes. The vegetation is wetter and denser than the forest around the main falls: giant ferns, climbing vines, and epiphyte-laden trees create a tunnel of green that admits minimal light and maximum humidity. The trail surface is mud, roots, and rocks — a combination that requires attention to every footstep and makes hiking shoes (not sandals) an absolute requirement.

Two stream crossings interrupt the climb. The streams are the same watercourse that feeds the main falls below — clear, cold mountain water rushing over mossy rocks. Crossing them requires stepping on slippery rocks or wading through knee-deep water, depending on the flow level. In dry season, the crossings are manageable for any reasonably agile person. After heavy rain, they can be genuinely challenging, and the guide may advise against attempting the upper trail if the water level is high.

The ascent takes 20-30 minutes, depending on pace and the number of stops to catch breath (the combination of altitude, humidity, and steep terrain ensures you will need them). The forest changes subtly as you climb: the trees grow taller, the understorey becomes more open, and the sound of the upper falls builds from an undertone to a roar.

### The Reveal

The upper falls announce themselves acoustically before they are visible. The sound grows from a distant rumble to a bass-heavy roar that vibrates through the ground and the air simultaneously, creating an anticipation that builds with each step. Then the trail rounds a final bend, the jungle opens, and the upper falls are there.

The cascade is a single column of white water — not the delicate curtain of the lower falls but a concentrated, powerful stream dropping 20-25 meters from a notch in the rock face. The water volume is substantial — all the water that eventually feeds the famous curtain below is concentrated here in a single forceful column that hits the pool below with a sound and energy that is felt physically.

The pool at the base is circular, deep, and surrounded on three sides by near-vertical rock walls covered in ferns, moss, and trailing vegetation. The jungle presses in from the top of the walls, creating a natural amphitheater that traps the sound and mist of the falls. The light — filtered through the canopy high above, diffused by the mist, reflected by the wet rock — has a quality that photographers describe as "impossible" — too even, too green, too cinematic to be natural, yet entirely natural.

### The Water

The pool at the base of the upper falls is deep — 2-3 meters in the center — and cold. The water originates high on Mount Rinjani's slopes, traveling underground through rock and volcanic soil before emerging at the spring that feeds this watercourse. The temperature is noticeably lower than the ambient air — perhaps 18-20 degrees Celsius compared to the 28-30 degree air — and the first immersion is a shock that triggers an involuntary gasp and a rush of endorphin-fueled exhilaration.

Swimming in the pool is the upper trail's ultimate reward. The water is clear enough to see the rocky bottom even at depth, the walls of the natural amphitheater surround you with moss-covered rock and hanging ferns, the waterfall roars at one end, and the sky is visible as a bright patch of blue high above the surrounding jungle canopy. The experience of floating in cold mountain water in a volcanic-rock pool surrounded by primary rainforest — alone, or nearly alone — is one of the purest natural experiences available on Lombok.

The force of the falling water creates a turbulent zone immediately beneath the falls that should be avoided — the combination of downward force, underwater currents, and aerated water (which reduces buoyancy) makes the area directly beneath the cascade dangerous. Swim in the pool rather than under the falls, and stay clear of the impact zone where water meets pool.

### The Solitude

The upper falls' most valuable quality may be the solitude they provide. On a typical day at the main Benang Kelambu — especially during peak season — you share the waterfall with 20-50 other visitors, complete with the noise, the selfie sticks, and the general social activity that group tourism produces. At the upper falls, on the same day, you share the cascade with perhaps no one — or at most, one or two other visitors who have also made the effort to find and climb to this hidden second waterfall.

This solitude transforms the experience from social to personal. The waterfall speaks directly to you rather than to a crowd. The pool is yours to enter without waiting. The mist falls on your skin without competition. And the deep, reverberant sound of heavy water hitting rock fills your awareness without the overlay of human conversation.

The experience of a waterfall in solitude is qualitatively different from a waterfall in company. Both are beautiful. But the solitary waterfall creates a relationship between the visitor and the natural phenomenon that is intimate, direct, and unrepeatable — the same waterfall will sound different, look different, and feel different the next time you visit, and the memory of this particular visit, in this particular light, in this particular moment, becomes a unique and personal possession.

### Descending

The descent from the upper falls follows the same trail in reverse, and the downhill direction presents its own challenges — the steep, muddy sections that required effort on the way up require caution on the way down, as gravity adds momentum to every step and the slippery surface provides minimal braking. Take your time, use available handholds (tree roots and trunks are your friends), and let the guide set the pace.

The stream crossings are marginally easier downhill — you can see the far bank more clearly and judge your stepping-stone route with gravity's assistance. But the rocks remain slippery, and a fall here means a soaking at best and a sprained ankle at worst.

### The Comparison

Arriving back at the main Benang Kelambu waterfall — with its crowds, its selfie culture, and its well-maintained paths — creates an inevitable comparison with the upper falls you have just left. The main falls are beautiful, accessible, and democratically available to anyone who can descend a staircase. The upper falls are beautiful, remote, and available only to those who make the physical effort to reach them.

Neither is objectively better. But the experience of climbing to a hidden waterfall, swimming in its pool alone, and returning with a memory that most Benang Kelambu visitors will never create — this adds a dimension to the visit that the main waterfall alone cannot provide. You have been above the curtain, beyond the crowds, and into the jungle's deeper offering. The trail's difficulty was the price. The waterfall's beauty was the reward. And the ratio between price and reward — high effort for extraordinary return — is exactly what adventure travel promises but rarely delivers.

The upper Benang Kelambu falls exist within a broader context of central Lombok's waterfall landscape — a zone where the combination of altitude, rainfall, volcanic geology, and dense forest cover produces dozens of waterfalls within a relatively compact area. Many of these cascades are known only to local guides and the farming communities whose villages sit in the valleys below them.

Visiting the upper falls is an entry point into this landscape — a demonstration that the famous, accessible attractions are often just the beginning, and that the deeper you explore, the more the forest reveals. The same principle applies throughout Lombok: the places that require effort to reach are almost always more rewarding than the places that do not, and the traveler who is willing to climb a muddy trail, cross a slippery stream, and trust a guide's knowledge will consistently find experiences that the road-and-parking-lot tourist never encounters.
