Museums & Galleries in Mill Valley

Dust off your explorer's exploring khakis and your museum monocle for today's deal: a one-year Friend of Horus membership to the Rosicrucian Egyptian Museum for $15 (a $35 value). Membership includes free individual admission, 10% off museum store items, and priority entrance to new featured exhibits. The only hieroglyphic capable of expressing your delight will be an owl hugging a jackal's head on top of a human eyeball. Follow @Groupon_Says on Twitter.

Your ticket includes a mind-expanding movie about the cosmos, some live music you can dance to, and access to the observatory and all of Chabot's exhibits. Current exhibits delve into the scientific achievements and cosmology of the Maya, give you a most likely dehydrated taste of the life of an astronaut, and take you on a journey to the farthest reaches of the cosmos, among other things. And—weather permitting—you'll get to spy on other planets from either Nellie, the 36" reflector telescope that allows access to 180 degrees of night sky, or Rachel, the largest refractor in the western U.S. You'll have four hours to amble through the science center with a celestial concoction in one hand (drinks are $3–$5 at the cash bar) and your date in the other. After staring into the depths of distant galaxies, you can stare into the depths of each other's eyes over dinner at the Starlight Bistro or Celestial Café (not included in Groupon; reservations required).

Spread out among 132,000 square feet and three levels are a variety of permanent and temporary exhibits that represent the museum’s goal of innovative inspiration. The recently opened, hands-on, and interactive exhibit Invention at Play examines the evolution of playtime from the hoop-and-stick of yesteryear to the portable holographic virtual wristwatches of today. The art, film, and music-focused Tech Virtual Test Zone conceptualizes ideas from the virtual world of Second Life with interactive wonders such as the Wall of Musical Buttons. The Wall allows visitors to experiment with note intervals in familiar musical melodies, and Mashup Masterpiece gives visitors the ability to add their own creative modifications after observing an artist's artistic process. Aspiring weatherpersons can learn about the powers of wind, water, and sun in Green by Design, or budding Beakmans can perform various science experiments in the Exploration Gallery. Keep the stimulation going while giving tired legs a rest with the included educational IMAX movie. Check out current offerings such as Arabia or Under the Sea or peruse the schedule for other upcoming shows at The Hackworth IMAX Dome Theater.

Established more than a century ago inside Golden Gate Park, the Conservatory of Flowers houses a vibrant array of rare, exotic, and tropical plants and flowers. Mosey through the National Historic Landmark’s aquatic plants display, where peaceful sounds of cascading water complement the sight of giant Amazonian water lilies with pads up to 6 feet in diameter, leading to their frequent use as trampolines for spider monkeys. The highland tropics area invokes the appearance of misty cloud forests on tropical mountaintops blooming with hundreds of delicate orchids and a forest of stunted trees. A century-old giant philodendron resides in the lowland tropics display alongside the conservatory's cycads, which predate the dinosaurs and many veteran game-show hosts. The potted plants display shows off nature's bounty inside copper urns from India and hand-incised ceramic pots from Burkina Faso, and the temporary Playland at the Conservatory re-creates the historic Playland at the Beach from San Francisco's West End with model trains, miniature famous attractions, and memorabilia from the fair.

Nestled in the shadow of the Golden Gate Bridge, the Bay Area Discovery Museum entices children's inquiring minds with a host of exhibits modeled after the surrounding sea and city. The Wave Workshop lets kids explore the San Francisco Bay's ecology and test their own boat designs against simulated wind and waves. In the 2.5-acre Lookout Cove which overlooks the bay itself, a 23-foot-tall Golden Gate Bridge entices children to put on hardhats and help construct a giant model.

Established in 1968 in honor of Ernest Orlando Lawrence, UC-Berkeley's first Nobel laureate, The Lawrence Hall of Science aims to inspire the scientists and innovators of the future. Their hands-on exhibits allow children and adults to see and touch a fascinating variety of displays and projects. The animated, interactive Science On a Sphere globe, for example, uses actual scientific data to depict the expanding wave patterns of tsunamis and the massive storms triggered by thoughtless butterflies. To learn more about seismic activity, guests head to the Forces That Shape the Bay outdoor park to ride an earthquake simulator. Kids can climb atop a life-size model whale or through the double helix of a huge DNA sculpture, or work with students from the Berkeley Engineers and Mentors program to design and build a prototype in the Ingenuity Lab.

The museum also sparks imaginations with an interactive planetarium and 3-D theater. Its affiliation with the university makes it an ideal spot for educational camps and classes, as well as community events, including robotics competitions.
