No backyard barbecues for them: When Prince William and girlfriend Kate Middleton celebrated summer's last hurrah, they did it with style—in this case, a weeklong getaway to the Mediterranean island of Ibiza.

Boarding a 42-ft. yacht, the merry group took a day trip to nearby Espalmador, where Will and Kate, both 24, indulged in mud baths famous for their supposed healing qualities.
