Slide show music ideas!!!!!!!!?

So i make dvd photo slide shows of our vacations…we usually go to the beach out east but this year we headed west to Yellowstone National Park…i am out of ideas for music for the trip, because songs like “life is a highway” Route 66″ etc., dont seem to fit with the pictures or the awesome nature we saw. So i could use some help on two things. (1) ideas for songs for the photo slideshow, maybe something fun upbeat sounding, family-oriented, or idk (2) and maybe some instumental songs that would sound nice and flow with the nature and exploring.

Much thanks!
