The Colosseum at Night

On this spookily evocative tour, available through October, a guide leads a small group through the Roman forums into the Colosseum, the ancient amphitheater that hosted gladiatorial contests, animal hunts and grisly executions. With the gates locked and the crowds gone, you descend below the arena into the underground passages and holding cells where doomed souls once awaited their grim fate. Goosebumps guaranteed.

Piazza Porta Portese (Trastevere)
Via di Porta Portese
00153 Roma, Italy
Sundays 7:00 a.m. – 1:00 p.m.

Rome is a shopper's paradise but nothing compares with this weekly extravaganza. In a mammoth sprawl of stalls, you can find everything from the latest tablets and smart phones to rare books and antique vases. Expect good-humored crowds, a nonstop cacophony—and haggling. The basic rule: The stated price just starts the negotiations. If you don't know Italian, you can get by with "troppo!" (too much) and hand gestures.

It's a boat! It's a bar! It's a restaurant! No place in Rome—or elsewhere—looks like Baja-Roma, a floating fantasy moored on the Tiber off the Piazza del Popolo. Linger over a leisurely lunch prepared with organic ingredients. Sip an aperitivo while watching the sunset. Enjoy a gourmet dinner under the stars. Nestle with your sweetie on cozy pillows in the loft-like interior. Rome doesn't get more romantic!

Capuchin Crypt

For a mix of the macabre and the mesmerizing, venture into the underground chapels of the Capuchin church, festooned with the bones of some 4,000 monks who died between 1528 and 1870. Skulls, pelvises, shins, arms and fingers form intricate altarpieces, pyramids and arches. The chilling message (inscribed in three languages) will haunt you: "We were once like you. You will be like us." Not for the squeamish.
