We're flying into Las Vegas early on a Wednesday in August and flying out 10 days later, late on Saturday evening (red eye). We need to be in Boulder, CO three days after we arrive in Vegas, on Saturday, for a wedding.
We're thinking of booking it to CO on I-15/I-70, maybe spending a night in Zion and Arches along the way, and then meandering our way back to Vegas. On the way back, we'd like to see the North Rim of the Grand Canyon, perhaps the sand dunes in southern CO, and any other amazing/interesting things that we have time for.
We're somewhat experienced (mostly eastcoast) backpackers, but this is our first roadtrip and any itinerary/sites suggestions for national parks or minor backpacking in the neighborhood would be really appreciated! ...of course it'd also be fun to spend a night or two in vegas at the end of the trip since we've never been there before.
