WANT TO TAKE a trip to the woods and be sure of encountering wildlife you don't see every day? Start your trip indoors at one of the many nature centers staffed by professional park naturalists throughout the area. The centers, located in some of the county, national and regional parks, serve as microcosms of the outdoor environments in which they sit.
Almost all serve as starting points for nature trails and give printed guides for identifying the species and ecosystems you'll encounter in the parks. You can examine live or dead specimens of the animals that dwell in the surroundings. Return to the center after a hike and a ranger or guidebook can help you identify any unusual mammals, birds, bugs or plants you may have found or answer any other questions.
Many centers feature libraries and special hands-on exhibits for children. The centers all offer nature hikes and programs. (Call for schedules.) Many also offer classes for preschoolers through adults. They will gladly arrange special programs for groups of scouts, schoolchildren, seniors and others -- but call ahead.
Note that some centers may keep shorter winter hours, but not before you can watch the change in seasons. Here, in a nutshell, is a rundown on some of the local programs: THE DISTRICT
ROCK CREEK NATURE CENTER --
In Rock Creek Park, 5200 Glover Rd. NW. 202/426-6829. Open 9 to 5 daily. Exhibits are designed around the flora and fauna found in the park, "like an orientation to going out in the park and finding these things for yourself," says supervisor Dave Smith. Two trails lead through the woods around the center; you can explore on your own or on ranger-led tours given on weekends. Max the Owl has been a popular attraction since his wing was broken by a car 17 years ago -- though he's not very friendly. The center also includes the nation's only Park Service planetarium, offering weekend shows at 1 p.m. for ages four and up, and more sophisticated shows at 4 p.m. for ages seven and up. VIRGINIA
PRINCE WILLIAM FOREST PARK VISITORS CENTER --

Exhibits, talks, hikes and videos focus on the park and the land's history (including how the Civilian Conservation Corps built the park in the 1930s), the National Park Service itself, Indian life, farmland and machinery from the Old Pyrite Mine in the park. (A two-mile hike will take you to the mine ruins.) A "touch-me" table for children includes deer antlers and an inactive beehive. The staff will show nature films on request. The 35 miles of hiking trails include a quarter-mile paved route for the disabled, with audio boxes explaining the sites along the way.

You can also see a litter of baby turtles as well as a collection of grown-up turtles, snakes and assorted reptiles and fish in cages and an indoor pond. Meet Jonesey the baby opossum, who the nature center adopted last month after his mother was run over by a car -- he lets people pet him. Wooded trails around the center lead to two ponds and the only swamp in Arlington.

Sometimes the naturalists will let you feed them worms or slugs. Barnie the Barn Owl has lived in a small barn in the center since he was mistakenly taken out of a nest 10 years ago. You can also see two screech owls adopted by the center after they suffered injuries in the wild. If the owls won't sing for you, you can hear owl voices on tape. And you can view a beekeeping exhibit. A five-minute walk to the park takes you to Old Maryland Farm, which features pigs, goats, sheep, chickens, ducks, turkeys and rabbits as well as organically grown crops. The barn has exhibits on organic farming and conservation.

Home to a few wounded birds, the center also features aquariums full of snakes, salamanders, turtles and fish, and a variety of stuffed wildlife. In Discovery Niche, children can smell herbs and try to figure out what they are. The library has nature books for youngsters and hands-on artifacts and puppets (turn the tadpole inside out and it becomes a frog). If you shut out the lights in one corner you can view the constellations on the ceiling. A short hike through wooded trails takes you next door to Brookside Botanical Gardens, which is always full of color. Nature flicks are shown Saturdays at 11, 1 and 3; Sundays at 2 and 4.
HAWK'S REACH NATURE CENTER --
Little Bennett Regional Park, 23701 Frederick Rd., Clarksburg. 301/972-9458. Open to the public 1 to 5 Saturdays only through October. (The center was converted from the campground store in the middle of the campground and the limited hours are to prevent the public from disturbing campers.) The center includes an extensive collection of reptiles, amphibians and insects. Exhibits challenge children to solve nature puzzles. At the bird table, for instance, visitors are given all the raw materials to build a bird's nest and invited to try, noting that they have the advantage of having hands that birds don't. "It gets across the idea that this is not as easy as it looks," says Park Naturalist Denise Gibbs. A butterfly and hummingbird garden is outside.

Curiosity Corner features snakes, fish, turtles and a microscope. Once outside, you can hike to Lake Frank.
