No summer beach seems to capture the special vibe better than Hawaii's Waimanalo Beach, on the southeast shore of Oahu. The day ends a one-minute walk from the beach at Hale Nalo, a three- suite rental home with the all-new Zen Treehouse loft. “Guests often have the entire beach all to themselves,” says Hale Nalo owner Herlinda Lopez. “They always mention this while deliriously happy.” Rates from $165.
