Depends on the season, the quota fill up fairly quickly starting from 3 months until 3 days in advance of the hiking day. Holidays and weekends are definitely the most booked days
  • Furthermore, every hiker must present a health certificate/ fit to climb letter from a clinic or doctor during registration to prove they have an adequate level of fitness. In practice, this will be a simple medical checkup at local clinic that has to be conducted one day before hiking day.
  • The National Park recommends the climb only until Kalimati campsite, thus the National Park insurance only cover until safe hiking zone in Kalimati. Climbers still allow to climb the peak of Mt Semeru but at their own risk.
