During your Denver vacation, don't miss these great establishments and attractions:

Butterfly Pavilion & Insect Center
A walk through the butterfly conservatory introduces the visitor to a world of grace and beauty. The constant mist creates a hazy habitat to support the lush green plants that are both food and home to the inhabitants. If you stand still for a few minutes, a butterfly might land on you, but don't try to pick them up -- the oils on your hands contaminate their senses, interfering with their ability to find food. One display describes the differences among butterflies, moths, and skippers, and color charts help with identification. (A butterfly guide is available for a nominal fee.)In the insect room you'll discover that honeybees beat their wings some 200 times per second, and beetles comprise one-fifth of all living things on earth. Meet arthropods (the scientific name for insects) that are native to Colorado, and see exotic species from around the world. A fascinating "touch cart" allows you to get up close to a cockroach or tarantula, assuming that you really want to.A 31,000-square-foot expansion was completed in 2004, housing "Shrunk!" -- giant robotic insects (it can be scary for little ones) and nifty interactive exhibits about the biomechanics of bugs. Also on the premises are a large gift shop and snack bar. Outside, a 1/2-mile nature trail meanders amidst cacti and other desert-friendly plants. Allow 2 to 3 hours.

Denver Mountain Parks
Formally established in August 1913, the city's Mountain Parks system immediately began acquiring land in the mountains near Denver to be set aside for recreational use. Today it includes more than 14,000 acres, with 31 developed mountain parks and 16 unnamed wilderness areas that are wonderful places for hiking, picnicking, bird-watching, golfing, or lazing in the grass and sun.The first and largest, Genesee Park, is 20 miles west of Denver off I-70 exit 254; its 2,341 acres contain the Chief Hosa Lodge and Campground (the only overnight camping available in the system), picnic areas with fireplaces, a softball field, a scenic overlook, and an elk-and-buffalo enclosure.Among the system's other parks is Echo Lake, about 45 minutes from downtown Denver on Colo. 103. At 10,600 feet elevation on Mount Evans, the park has good fishing, hiking, and picnicking, plus a restaurant and curio shop. (Note: A fee program is being tested here; the charge is $10 per carload.) Other parks include 1,000-acre Daniels Park (23 miles south of Denver; take I-25 to Castle Pines Parkway, then go west to the park), which offers picnic areas, a bison enclosure, and a scenic overlook; and Dedisse Park (2 miles west of Evergreen on Colo. 74), which provides picnic facilities, a golf course, restaurant, clubhouse, and opportunities for ice-skating, fishing, and volleyball.

Denver Museum of Nature and Science
The largest museum of its kind in the Rocky Mountain region, the Denver Museum of Nature & Science features scores of world-renowned dioramas, an extensive gems and minerals display, a pair of Egyptian mummies, a terrific fossil collection, and several other award-winning exhibitions. The museum focuses on six areas of science: anthropology, health science, geology, paleontology, space science, and zoology.The newest permanent exhibition, "Space Odyssey," opened in 2003. Visitors experience a carefully crafted mix of exhibits, live programming, digital multimedia, and interactive modules that engage them in contemporary stories of space exploration. The Gates Planetarium, which also reopened in 2003 after renovations, has been transformed into a state-of-the-art digital planetarium. The new facility has an advanced computer graphics and video system, unlike any planetarium in the world.The "Prehistoric Journey" exhibit traces the history of life on earth through 3.5 billion years. Dinosaur skeletons, fossils, interactive exhibits, and dioramas of ancient ecologies make this one of the museum's most popular attractions, especially with children.Another popular exhibit is the "Hall of Life," which focuses on the science of the human body. Using a magnetic card, visitors gather information on themselves as they move through the interactive exhibits. When finished, they receive a printout about their own physical condition.An IMAX theater (tel. 303/322-7009) presents science, nature, or technology-oriented films with surround-sound on a screen that measures four and a half stories tall. Allow 2 to 4 hours.

Adam's Mark Denver
This striking, sprawling complex consists of two buildings that were designed by onetime Denver resident I. M. Pei in the 1950s, joined as Denver's first convention hotel in the mid-1990s. Linked by a pedestrian bridge that crosses Court Place, it combines the 22-floor Tower Building (a former Hilton and Radisson property) and the Plaza Building (a former May D & F department store) into the largest hotel in the Rocky Mountain region. From the upper floors of the Tower Building, the west-facing rooms have marvelous views of the Front Range, and it's a real treat to relax and watch the lights of the city come on as the sun makes a graceful exit behind the curtain of mountains.Rooms, on average, are larger than the norm in downtown Denver, and the range of suites is dizzying. The decor of both guest rooms and public areas is classical, with an emphasis on brass, marble, and solid woods such as oak and mahogany. Colors are muted and restful.Facilities:3 restaurants (1 Italian, 2 cafes); 3 lounges; heated outdoor pool; health club (weight room, cardiovascular machines); sauna; business center; 24-hr. room service; coin-op washers and dryers; dry cleaning; executive level (concierge and business services, full breakfast, local and national newspapers, and happy hour w/hors d'oeuvres, coffee, and desserts).

Innkeeper of the Rocky Mountains
A member of Hostelling International, this centrally located hostel is in a bustling urban area just off Colfax Avenue, within walking distance of more than 50 restaurants as well as all the major downtown attractions. Facilities include a community kitchen, lockers, laundry machines, Internet access, and a cafe. Each dorm room has no more than four beds; there are also five private bed-and-breakfast rooms in two adjacent houses. The front door is always locked and someone is on the premises all night. Under the same ownership are a nearby B&B and guesthouse, and a lodge in the Rockies.

Brown Palace Hotel
For more than 100 years, the city's finest hotel has been the place to stay for anyone who is anyone. It combines great rooms and amenities with the intangibles: interesting history, romantic atmosphere, regional personality, and impeccable service. A National Historic Landmark, the Brown Palace has operated continuously since it opened in 1892. Designed with an odd triangular shape by the renowned architect Frank Edbrooke, it was built of Colorado red granite and Arizona sandstone. The lobby's walls are paneled with Mexican onyx, and elaborate cast-iron grillwork surrounds six tiers of balconies up to the stained-glass ceiling. Every president since 1905 (except Calvin Coolidge) has visited the hotel, and Dwight Eisenhower made the Brown his home away from the White House. His former room, now known as the Eisenhower Suite, is a vision of stately elegance, with a preserved dent in the fireplace trim that is the alleged result of an errant golf swing. There are also lavish, unique suites named after Teddy Roosevelt, Ronald Reagan, and The Beatles, each recently redecorated.Standard rooms are also lush and comfortable, either Victorian or Art Deco in style with reproduction furnishings and fixtures. Each has a desk, a duvet, and individual climate control. The clientele is a mix of leisure travelers and businesspeople with a taste -- and a budget -- for luxury. The staterooms on the ninth floor are especially enticing, with cordless phones, big-screen TVs, fridges, fax/printers, and safes. The water's great here: The Brown Palace has its own artesian wells!
