Travel-health advice must be personalised.

This page provides general preparation guidance, not a diagnosis or prescription. Speak with a travel-health doctor or clinic, ideally at least four weeks before departure, especially for pregnancy, children, long stays, medication or existing medical conditions.

Before you travel

Good preparation makes the jungle feel easier.

Bukit Lawang is tropical, humid and physically active. A few sensible preparations can greatly improve comfort and reduce avoidable risk.

01

Book a travel-health appointment

Discuss your complete route, trek length, rural exposure, medical history and planned activities.

02

Review vaccinations

Check routine vaccines and ask about hepatitis A, typhoid, hepatitis B, rabies, polio and Japanese encephalitis.

03

Choose suitable insurance

Confirm that trekking, hospital treatment, transfer and medical evacuation are covered.

04

Bring regular medication

Carry enough in original packaging, plus prescriptions and essential medical information.

05

Tell us about health concerns

Share allergies, asthma, diabetes, heart conditions, previous injuries, pregnancy or limited mobility before booking.

06

Save emergency contacts offline

Store insurer, accommodation, guide and emergency numbers before entering the rainforest.

Current tropical-health guidance

Protect yourself from mosquito-borne illness.

Dengue and chikungunya are mainly spread by daytime-biting mosquitoes. Malaria mosquitoes are most active from dusk to dawn, so protection matters around the clock.

Dengue & chikungunya

Use effective repellent, cover exposed skin and continue protection during daylight hours.

Mosquito prevention

Use DEET or icaridin/picaridin, long clothing, screened rooms and a sound mosquito net where appropriate.

Fever after travel

Seek medical advice promptly and clearly mention recent travel to rural North Sumatra.

Malaria advice differs between authorities

Bukit Lawang is in rural North Sumatra. UK and German guidance generally describe Sumatra as low risk, while the US CDC lists rural Sumatra as a malaria-transmission area where prescription prevention may be recommended.

Do not begin antimalarial medicine based only on a website. Ask a qualified clinician to assess your exact itinerary, accommodation, trek length, medical history and personal risk.

Vaccinations

Routine vaccines should be current. Hepatitis A is commonly recommended; other vaccines depend on your itinerary and health.

Rainforest responsibility

Wildlife safety and jungle safety belong together.

Ethical behaviour protects visitors, guides and wildlife. The forest is not a controlled environment, and conditions may change quickly.

Frequently asked questions

Clear answers before your trip.

Do I automatically need malaria tablets?

Not automatically. Official authorities assess Sumatra differently, and the decision depends on your itinerary and personal risk. Discuss Bukit Lawang’s rural setting and your exact trek plans with a qualified travel-health clinician.

Which vaccinations are compulsory?

Requirements partly depend on where you arrive from. Routine and recommended travel vaccines should be reviewed individually. Yellow-fever proof may be required when arriving from a country with yellow-fever transmission risk.

Can I trek with a cold or flu?

Please tell us and postpone the wildlife trek. Respiratory infections can be transmitted between humans and great apes, and jungle exertion may worsen your own symptoms.

Is trekking suitable for children or older travellers?

It may be, but the route should match fitness, balance, heat tolerance and medical needs. Contact us before booking so we can discuss a shorter or less demanding option.

What happens if the river is too high?

The guide will change, shorten or cancel the river activity. Safety takes priority over completing the original itinerary.

What should I do after an animal bite or scratch?

Wash the wound immediately with soap and running water and seek urgent medical assessment, even when the wound looks small and even after pre-exposure rabies vaccination.

Plan responsibly

A safer trek begins with an honest conversation.

Tell us your preferred trek, fitness level and practical concerns. Our local team will help you choose an experience that respects your wellbeing and the rainforest.
