The hills across from town and upriver, along the banks. Both are free and a short, but careful for blue lights drive from the distillery and brewery. You can have a whisky drink at the deerhammer (kickin moscow mules) before and after playing at the in-town park features if that's your thing.
That's all I got for around there, which is just fine esp. for convenient access and location but there's surely a lot more around and between the two towns.
