A Glimpse of Ranu Kumbolo
If you’ve ever climbed Gunung Semeru, or even just have an interest in hiking, chances are you’ve heard of Ranu Kumbolo. This natural lake sits at around 2,400 meters above sea level, inside Bromo Tengger Semeru National Park (TNBTS), and is a beloved spot for many trekkers. In the local Tengger language, “ranu” means lake. Ranu Kumbolo spans roughly 15 hectares and is fed by pure mountain springs. Its serene and enchanting scenery makes many hikers refer to it as a “hidden gem” nestled between Gunung Bromo and Gunung Semeru. Interestingly, Ranu Kumbolo isn’t just a rest stop on the way to Mahameru summit, many travelers actually make the lake their main destination. You can pitch your tent by the shoreline, watch the sunrise slowly rise behind the hills, or marvel at the starlit sky and milky way, all those moments combine to create a memory you’ll never forget at Ranu Kumbolo.
How to Reach Ranu Kumbolo
If you’re planning to experience the beauty of Ranu Kumbolo, there are two key stages on your journey: first, reaching the basecamp at Ranu Pani, and then trekking up to the lake itself. Here’s a guide to help you navigate each step.
1. Getting to Ranu Pani Basecamp
Your journey begins at Desa Ranu Pani, the official entrance to Gunung Semeru trail in Lumajang Regency, East Java. You have two main starting points:
- From Malang
Start by taking local transport or a ride-share to Arjosari Terminal. From there, head to Tumpang, then catch a rented jeep to Ranu Pani. You can reserve the jeep through hiking communities or tour operators. - From Lumajang
Take public transport to Senduro, then continue on foot or with a jeep or motorcycle taxi to Ranu Pani. This route tends to be quieter than the Malang route, but it remains reliable.
Once you arrive at Ranu Pani, you’ll need to process your SIMAKSI permit (Conservation Area Entry Permit). You’ll also usually have to show a health certificate issued by an accredited clinic or health center. So, make sure all your documents are ready before you depart!
2. Trekking Up to Ranu Kumbolo
After handling the paperwork, it’s time to hit the trail. From Ranu Pani basecamp, the trek to the lake takes around 4–5 hours, featuring a gradual incline that’s manageable even for beginners. Along the way, you’ll pass several key rest points like Landengan Dowo, Watu Rejeng, and Oro-Oro Ombo. These spots not only serve as rest stops but also treat you to uplifting views that reignite your spirit. After crossing the scenic lava savannah of Oro-Oro Ombo, famous for its purple verbena flowers, you’ll arrive at your destination: Ranu Kumbolo. At that point, any fatigue you felt will melt away as you take in the tranquil lake and fresh, revitalizing air.
