Sustainable tourism

Altaï always aims to have as little impact on the environment as possible. As adventure and wilderness travel experts who run trips to some of the most remote parts of the world, we take responsible tourism very seriously.

Since the beginning, we have advocated for responsible tourism and the importance of equitable and sustainable principles. Harmonising these fundamentals ensures a fair distribution of economic benefits, improved working conditions for local teams and an increased awareness of the importance and practice of environmental protection.

  • Avoid dropping litter - use bins or carry your rubbish with you.
  • Use drinking water sparingly - avoid wasting water, take showers not baths, report leaks, etc..
