I apologize, but “askoy” is not a recognized real-world location for which verifiable weather data, typical costs, or specific activities can be provided. My instructions explicitly state: “CRITICAL: Only use real, verifiable data. Never make up statistics, prices, or facts.”

To create a practical backpacking guide that adheres to these strict requirements, I need a real geographical location.

Please provide a real city, region, or country, and I would be happy to generate a guide based on verifiable data.
