I am unable to create a backpacking guide for “balti” as requested.

“Balti” is a style of curry or a cooking pot, not a geographical location. The core instruction for this guide is: “CRITICAL: Only use real, verifiable data. Never make up statistics, prices, or facts.” Without a specific geographical location, it is impossible to provide real, verifiable data regarding summer weather, typical costs (accommodation, food, activities), specific tips, or attractions.

If you can provide a specific city, region, or country you meant, I would be happy to generate a guide adhering to all your requirements with verifiable information.
