The climate is equatorial. Due to its position straddling the equator, Indonesia experiences a relatively uniform climate throughout the year, with variations greatly moderated by maritime influences. The seasons are therefore less pronounced. However, generally speaking, the south is cooler and drier. Average temperatures range between 24 and 35°C.

The electrical current is almost always 220V, except in some places where it is still 110V. Make sure to check before plugging in a foreign electrical device.

Altaï Travel works towards more responsible tourism and is committed to organizing trips that respect fair and sustainable principles.

Harmonizing practices ensures:

• Fair distribution of economic benefits
  
• Improvement of working conditions for local teams and raising their awareness of environmental protection
  
• Informing travelers about respecting local populations and the environment, and collecting their feedback upon return
  

• Avoid leaving trash behind: dispose of it in bins or take it with you
  
• Use drinking water sparingly (prefer showers over baths and report leaks) and avoid wasting it (prefer biodegradable soaps for washing, etc.)
  
• Avoid damaging cultural sites: do not touch statues, do not move stones or objects, etc.
  
• Prefer exchanges over gifts (gifts that are too valuable relative to the local standard of living can destabilize the local economy)
  
• When walking, especially in fragile ecosystems, observe wildlife from a distance, stay on paths, minimize trampling, and do not take “souvenirs”: refrain from picking rare flowers or collecting fossils, etc.
  
• In some hotels, you may have individual air conditioning. To avoid excessive energy consumption and greenhouse gas emissions, it is strongly recommended to turn it off whenever you are not in the room.
