I live just outside Jim Thorpe and you got a lot of good suggestions.

I'd only add that the restaurant recommended at Hofford Mill is actually down the river in Weissport (across from Lehighton). Hiking the Weissport Canal towpath section of the D&L Trail before/after could tie into that

Also hiking the Switchback Rail trail between Jim Thorpe and the Much Chunk Lake dam overlook is nice.

Some of the trails at Hickory Run S. P. are nice too but go on Sunday as Saturday is the last day of regular deer season.
