If you want to book a tour for the coming days, please contact us via WhatsApp (+62 85183928215) in addition to filling out the enquiry form. Mount Rinjani National Park has an entrance ticket system, that limits numbers on the mountain. We have to ensure there are tickets available, before we can confirm a trek (hence the reason why we need as much notice as possible, and you should try to book in advance, rather than leaving it to the last minute). Sometimes the internet in Senaru drops-out, so please contact us via phone or WhatsApp if your enquiry is urgent.
