We have four words for you: surf camp in Morocco. Far out, right? The boys can book with Surf Maroc, a reliable outfitter in this fishing village.

Even if the fellas aren't hard-core mountain men, they'll be more than stoked to set up camp in the new Outlook Lodge.

They can hike in Pikes Peak National Forest, raft the white waters of Royal Gorge (American Adventure Expeditions runs guided trips), or cast a line for trout.
When to Go: The lodge is open year-round, but Green Mountain Falls offers the most varied activities during summertime.
There are obvious perks to a party-bus, but they're not the classiest of rides. Our solution? Chartering a private railcar.
