You can technically bring your own tent, but honestly, it’s almost never necessary and usually creates more hassle than it’s worth. Lombok-Indonesia.org provides high-quality tents, air mattresses, and full camping equipment as part of every package, so porters already know exactly how to set up the standard shelter efficiently at camp. The system works.
If you bring your own tent, you either carry it yourself, adding serious weight to your day pack, or ask porters to carry it, which displaces space they’d normally use for communal gear, food, and cooking equipment. The porters have enough to carry already. Their loads are heavy, and adding personal gear pushes things into unhealthy territory.
The tents provided by the team are selected specifically for Rinjani’s wind and temperature conditions, and they’re maintained and inspected regularly. Your personal weekend camping tent might not hold up as well on the exposed crater rim. There’s also the logistical question of where to store it before and after the trek while you’re traveling around Indonesia.
For the vast majority of trekkers, the smarter move is to rely on the included equipment, travel lighter, and let the porters handle camp setup while you focus on the hike itself. Save your energy and your luggage space for things that actually matter on the mountain.
