For tours that include the Ijen night hike, JVTO includes a mandatory health screening run by approved medical staff. The aim is to reduce the risk of sending unfit guests into a demanding environment with sulphur gas and steep trails.
Key points:
- Screening takes place before the hike, often at your accommodation or a partner clinic.
- Basic checks are done (for example blood pressure, oxygen saturation and relevant medical history).
- Results are recorded and can be used to confirm whether the hike is appropriate.
- The certificate is BSrE (Balai Sertifikasi Elektronik / BSSN) electronically signed and traceable to the licensed doctor's SIP, which helps prevent fake or self-issued certificates.
Full details, including what happens if you are not cleared, are explained on Ijen Health Screening.
