The Manaslu Circuit Trek requires several permits due to its restricted area status. Trekkers must obtain a Manaslu Restricted Area Permit (RAP) along with the Manaslu Conservation Area Permit (MCAP) and Annapurna Conservation Area Permit (ACAP). These permits must be arranged through a registered trekking agency and require trekking with a licensed guide. https://nepaltrekkingroutes.com/blog/manaslu-circuit-trek-permit
