What is kawah Ijen health license
A Kawah Ijen health license is a medical clearance/certificate required for visitors who want to hike to the Kawah Ijen crater in East Java, Indonesia.
What it is
-
An official health certificate stating that you are fit to hike and be exposed to sulfur gas.
-
It is required because Kawah Ijen has toxic sulfur dioxide (SO₂) gas, which can be dangerous—especially for people with certain health conditions.
Who needs it
-
All visitors (domestic and international tourists) are typically required to show it before entering the hiking area, especially when gas levels are monitored strictly.
What the certificate usually confirms
That you do not have:
-
Asthma or chronic respiratory diseases
-
Heart disease
-
High blood pressure (hypertension)
-
Pregnancy
-
Other conditions that could be worsened by sulfur gas or strenuous hiking
Where to get it
-
From a local clinic, health center (Puskesmas), hospital, or sometimes designated medical posts near Banyuwangi/Bondowoso
-
It is often issued the same day after a brief check (blood pressure, basic health questions)
Validity
-
Usually valid for 1–2 days only (very short-term)
Why it’s enforced
