Disc golf.
I don't know the holes in the area, but I'm sure they're there and probably very breath taking. Disc golf is a great semi slow paced activity that's cheap and great for getting to know each other. Good ice breaker if the guys don't know each other very well. Half hike, half game, activity that mixes well with booze.
Those that have never played can easily buy a good starter set for $30 ish with a driver, mid range (use this if you haven't played before, the driver will just curve like crazy if you don't have the technique down, the mid range is more forgiving) and putter.

I have this one and still use these discs on occasion even though I've added more discs. $30 is a good price for it. Don't forget to write names and phone numbers on the inside of the discs for ID purposes or if it gets lost.
Grab beers and drink them while chucking a few rounds. A plastic bag or cloth bag is more than good enough to keep discs and beers while playing the course.
