Rinjani Trek Management Board
Lombokandgilis
Coordinating the local tourism, Rinjani Trek Management Board offers information about the Gunung Rinjani National Park, local craft and culture, nature and wildlife, and the Senaru Villages which inhabit the hillside of this beautiful terrain, where tours and accommodation are on offer to visitors.
Their website offers detailed advice on local etiquette, avoiding any unwitting faux-pas, but by organising your visit through the Rinjani Trek Management Board, particularly to spend any time in the villages, you can make sure you get the best from your time there.
They do warn you to be sure who you're booking with and to contact Rinjani Trek Management Board directly, as fake operators offer cheaper but risky excursions under their name.
