Kerta Gangga Waterfall in June

June daytime highs in this part of north Lombok are around 24°C, with overnight lows near 17°C. Rainfall is approximately 40mm across 4 days, usually as brief afternoon showers. Humidity is in the mid-70s — much more comfortable than rainy-season levels.

Kerta Gangga's twin-falls structure is at its most dramatic in June. Both drops carry strong flow, the parallel curtains of water create the side-by-side effect that makes the falls famous, and the plunge pool below receives the combined volume. By August one of the two drops will have noticeably narrowed; June is when both look their most equal.

Pool clarity in June is moderate — visibility around 1-2 metres, slightly clouded from upstream runoff but plenty clear for swimming. The sound at the viewing area is genuinely thunderous in June; even speaking loudly is hard.

The trail starts at a parking warung near the village, with the descent beginning almost immediately. There's no gentle warm-up — within a few minutes you're on a steep slippery section that requires care. The descent takes 15-25 minutes depending on conditions and your comfort with steep terrain.

The descent has at least three notable hazard sections: a slippery rocky stretch near the top, a muddy section through dense vegetation midway, and a final steep approach to the viewing area with limited handholds. A local guide knows the safer routes through each section and can stabilise you if you slip.

The viewing area at the base of the twin falls is dramatic. You stand level with the plunge pool, looking up at both drops simultaneously. Photography is exceptional — you can frame both falls in a single shot, which is rare for Lombok waterfalls.

Kerta Gangga in June is genuinely quiet. The combination of off-route location, mandatory guide, and challenging descent filters out almost all casual tourists. On a typical June day you might see 5-15 people at the falls through the entire day — sometimes fewer.

For solitude and best light, plan to be at the parking warung by 8-8:30am. The descent takes 15-25 minutes, putting you at the falls by around 9am with virtually nobody else there. The light reaches the falls best between 10am and 1pm. Late afternoon descents are not recommended because rain risk rises and the climb back up in fading light is hazardous.

Kerta Gangga's descent is not casual. Several visitors injure themselves each year by attempting it without a guide or in poor footwear. The key risks are:

• Slippery rocks: Rain or spray makes most rocks slick year-round. June has firmer trails than wet season but the rocky sections stay slippery.
• Steep gradient: Sections approach 45-degree slope. There are limited natural handholds.
• Mud patches: Even in June, dense vegetation keeps some sections shaded and damp.
• Limited rescue access: If you're injured at the bottom, getting you back up is slow and difficult.

The right preparation: trail shoes with strong grip (not flip-flops, not running shoes), local guide hired at the parking warung, descent in the morning with daylight to spare for the climb back, and willingness to turn back if conditions are worse than expected.

Kerta Gangga can be combined with Sendang Gile, Tiu Kelep, and Tiu Pupus on a longer day, but the descent is tiring enough that most visitors do Kerta Gangga as a focused half-day rather than as part of a multi-waterfall sprint. A reasonable combination: Sendang Gile in the morning (easy roadside), then Kerta Gangga in early afternoon when light is best, return for a swim and rest by mid-afternoon.

For a less demanding multi-waterfall day, substitute Tiu Kelep for Kerta Gangga — Tiu Kelep is also dramatic but the trail is much safer.

Parking is informal — 10,000-20,000 IDR. Local guide fee is 50,000-100,000 IDR per group, paid at the parking warung. There's no formal entry ticket. Warungs at the parking area sell water, snacks, and basic meals. Bring cash.

The drive from Senggigi takes 1.5-2 hours; from Mataram about 2 hours; from Senaru village 30-45 minutes. Most visitors come as part of a north Lombok trip. Scooter access is fine for confident riders; the final road is unsealed but rideable.

Beyond the descent itself: don't climb between the two falls (the rocks look bridgeable but are not), don't swim directly under either drop (debris risk is real with both falls feeding the pool), and don't attempt the descent if it's actively raining or if you've had any alcohol.

If you have any history of knee or ankle issues, consider alternative waterfalls. The Kerta Gangga descent is harder on joints than any other Lombok waterfall trail.

Phone signal is unreliable. Tell someone your plan if going alone.

June at Kerta Gangga is the twin falls at their strongest with quiet trails and the safest of the wet-to-dry transition months. The descent still demands care and a local guide, but conditions are about as good as they get. If you're choosing between June, July, August and September, June and September are the best months — peak flow without peak crowds.
