As a travel expert, my primary directive is to provide practical guides based on real, verifiable data. Unfortunately, “CADCA” is an acronym for the Community Anti-Drug Coalitions of America, a national organization, and not a geographical location or destination where one can backpack.

Therefore, I cannot provide accurate, verifiable information regarding summer weather, typical costs, specific activities, or attractions for a place called “CADCA,” as such data does not exist. My instructions critically prohibit making up statistics, prices, or facts.

If you had a different destination in mind, please provide its name, and I would be delighted to create a comprehensive backpacking guide for you, adhering to all the specified requirements.
