How sanitary are the toilets on Mt. Rinjani?

Honestly? They’re functional, but sanitary is not a word anyone who has used them would choose. The long-drop toilets at crater rim and lake campsites are deep pits with minimal privacy enclosures and no flushing system, running water, or regular cleaning service of any kind. During peak season, they get heavy continuous use and it definitely shows.

The smell can be genuinely intense, especially midday when the tropical sun hits them directly and amplifies everything. Bring your own toilet paper because supplies absolutely run out and you do not want to discover that at the wrong moment. Hand sanitizer is essential since there’s no water available for washing your hands afterward. Some trekkers even bring small packs of wet wipes for extra cleanup.

Some people prefer to simply avoid the facilities entirely and wait until they’re back on the trail where they can dig a proper cathole well away from water sources and other trekkers. It’s not glamorous, but it’s often more pleasant than the communal pit toilets after they’ve seen a few busy days of use.

The reality is that Rinjani is a remote volcanic wilderness area, not a serviced campground with maintenance staff. The toilet situation reflects that reality perfectly. Lombok-Indonesia.org’s porters maintain reasonable cleanliness around general camp areas, but they can’t change the fundamental infrastructure limitations imposed by operating on an active volcano with no plumbing. If you’re genuinely squeamish about basic bathroom conditions, you need to know this upfront and prepare mentally. It’s not going to be pleasant. But most trekkers find it’s a relatively small price to pay for one of the most incredible experiences of their lives, and it makes that first hot shower back at the homestay feel like the greatest luxury on Earth.
