It appears there might be a misunderstanding or a typo in the destination name “bender.” As a travel expert, I am unable to find a real, verifiable geographical location called “bender” for which to provide accurate weather data, typical costs, or specific attractions.

To fulfill the critical requirement of only using real, verifiable data, I cannot create a backpacking guide for a non-existent location. Generating hypothetical data would directly violate the instructions to “Never make up statistics, prices, or facts.”

If “bender” was intended to be a different location, please provide the correct name, and I would be happy to generate a guide adhering to all your specified requirements.
