Travel back in time
by spending the night in a lockhouse along the C&O Canal. Completed in 1850, the 184-mile canal was once lined with 57 small houses where lock keepers and their families lived. The waterway stopped operating in 1924, and the houses were abandoned. But in 2009, the National Park Service began restoring a handful of them. Six lockhouses can now be rented; all are brick or stone homes that are more than 170 years old and can sleep eight. The most modern are Lockhouse 6, near Brookmont, and Lockhouse 10, near Cabin John, which have kitchens and central air. Prices range from $70 to $150 per night. canaltrust.org
Laugh till you cry
at an after-hours storytelling event. Modeled after the New York City event called The Moth (heard on NPR), local storytelling gatherings are gaining popularity and can be a great way to break out of a nightlife rut. SpeakeasyDC (speakeasydc.com) draws a crowd each month to various venues with topics such as "bad mommy moments" and "stories about sex," and the group vets performers before each show. Story League (storyleague.org) is more casual--anyone can submit a story online or in person at the beginning of the night--but just as much fun. Arrive early to get a seat, then settle in as Washingtonians bare their souls and tell entertaining tales about everything from security clearances to online dating. Check the websites for schedules, locations, and prices.
Dig for buried treasure
at Gunston Hall, George Mason's 18th-century estate in Fairfax County. The staff gives volunteers tools and basic archaeological training, then lets them go to work. Among the many artifacts that been have found are coins, glass jewelry beads, and a two-tined fork with a bone handle from the 1760s. The field season goes from April to December; in the winter, volunteers can work in the lab, dating and categorizing unearthed objects. The house, designed in Chesapeake Georgian style, is also worth a visit. The intricate carvings in the Palladian Room are marvelous, and Mason's writing desk sits in the Little Parlor. 703-550-9220; gunstonhall.org.
Experience the thrill of rock-climbing
at Mather Gorge in Great Falls. The cliffs may be only 60 feet high, but with sheer and overhanging rock faces leading down to the roaring rapids of the Potomac River, the vertical slabs of Mather Gorge serve up the same sense of exposure and high adrenaline as a climb of 1,000 feet. A four-to-six-hour introductory climbing lesson through Go-Adventures includes rope handling, belaying, rappelling, and climbing techniques. Admission $125 for individuals; $80 per person for groups of four or more. 240-603-4150; go-adventuresports.com

Take in a panoramic view
at the Air Force Memorial, less than a mile from the Pentagon in Arlington.

Learn about the drug world
at the Drug Enforcement Administration Museum & Visitors Center in Pentagon City. This small museum takes visitors on a 150-year tour through the evolution of drug abuse in America. Youâ€™ll learn that it was the Civil War, not Vietnam, that created the first drug-addicted veterans.

See the sofa where John Wilkes Booth was treated
at the Dr. Samuel A. Mudd House.

Try open-air painting
amid some of the area's most glorious azaleas at McCrillis Gardens in Bethesda.

Maintained by Wheaton's Brookside Gardens, the shade-filled property has thousands of azaleas and rhododendrons as well as benches and a pavilion.

See an operating table that was used for amputations
at the National Museum of Civil War Medicine in Frederick. Nearly two-thirds of casualties in the war were caused by disease. Although you'll see all manner of ghastly things (a display on embalming, surgical tools including a saw) this museum is a lot more than a collection of period medical equipment. You'll also learn about the camp life of soldiers and about Dr. Jonathan Letterman, who created the system of battlefield care--using medics, triage, evacuation, and field hospitals--that's still the basis for what we use today. Adults $7.50, ages 10 to 16 $5.50. 301-695-1864; civilwarmed.org

Scavenge for history
by tracking down DC's Boundary Stones, the oldest monuments in the District. Installed in 1791 and 1792 to mark the boundaries of the nation's newly formed capital city, the 40 sandstone tablets run along DC's old diamond-shaped borders at about one-mile intervals. One side reads jurisdiction of the united states with a mile number, and the opposite names the state it borders; the two other sides say the year the stone was built and the compass variance. Although a handful of the original tablets have been destroyed or lost, history buffs have taken to uncovering the rest in parks, parking lots, even back yards throughout Maryland and Virginia. For a map, visit boundarystones.org

Feast in a Field
during a local stop of the Outstanding in the Field tour, a series of gourmet farm-to-fork dinners hosted in pastures and barns across the country.

The 174 campsites in the southern end of the park are only a half-hour walk from the College Park Metro station. The park features hot showers, bathrooms, and an RV area. Campsites are first come, first served and cost $16 a night. 301-344-3948; nps.gov.

Watch an elephant take a bath
during a tour of the National Zoo's elephant barn, otherwise closed to the public. Opened in July 2010, the concrete-and-steel barn is home to the zoo's three Asian elephants: 64-year-old Ambika, 36-year-old Shanthi, and ten-year-old Kandula. An hourlong tour takes you up to the mezzanine balcony, where you can look down onto the elephants as they play with one another, interact with elephant keepers, and, most days, take their morning bath. Tours ($40; $20 for ages 3 to 12; free for ages 2 and under) take place Wednesdays and Sundays at 8:15 am. 202-633-3057; nationalzoo.si.edu
Hunt for vintage furniture and other antiques
at barn sales in Frederick the third weekend of every month. At Chartreuse & Co. (301-874-1882; chartreuseandco.com), more than 15 antiques dealers gather to stock three barns with one-of-a-kind finds--recent hits have included mismatched industrial stools, vintage signs, and timeworn farm tables. Then wind along country roads to Stylish Patina (no phone; stylishpatina.com), where a handful of local dealers fill a whitewashed barn with vintage globes, burlap-covered benches, and silk-shaded chandeliers. The 50-acre horse farm also has animals that kids can pet and, in warm months, vendors selling barbecue and local produce.
Sip a local spirit

The beery aroma of fermenting mash wafts through the warehouse-like distillery as you learn about fermentation, distillation, aging, and bottling. A tasting of the three signature spirits--Mosby's white whiskey, Roundstone rye, and Watershed gin'follows some tours. Admission $5. 540-751-8404; catoctincreekdistilling.com

Stand in Eleanor Roosevelt's shoes
when you visit one of her favorite spots, the Adams Memorial by Augustus Saint-Gaudens in DC's Rock Creek Cemetery.

Play the sport of kings
at the Capitol Polo Academy in Poolesville. You don't have to be a millionaire to learn polo.
