This document proposes developing halal tourism around Lake Toba in North Sumatra, Indonesia. It notes that Lake Toba tourism has experienced a decline in recent years. The purpose is to revitalize tourism by focusing on all aspects of the tourist experience, including accessibility, activities, amenities, and ensuring halal food options. The business plan outlines improving access via vehicles, boats and planes; providing rest areas along routes; enabling places of worship; promoting local culture through dance, fashion, and museums; and guaranteeing halal culinary experiences. Successfully implementing this comprehensive plan could rapidly boost tourism, jobs and community incomes in the Lake Toba region. However, it will be challenging to realize without community collaboration and significant financial resources.
