Take a whitewater rafting trip, this time of year the waters of the Snake River are perfect! Some of the best rafting I've been on.
Have dinner at the Snake River Grill, had an incredibly good Grilled Halibut last time, also saw Harrison Ford there having a drink too.
The FBO normally tries to put you up in the Wagon Wheel, nice hotel for the price and easy stumbling distance from the Cowboy Bar.
For exercise take a hike up Snow King, great view from up top and about as good of a work out as a 4 mile jog.
Finally finish the trip off with breakfast at Bubbas and order the Mexican Scramble or some BBQ brisket for lunch, there's always a line so allow 2 hours for that.
In short just enjoy one of the nicest places in the country to be in July.
