LOCATION

The American Astronautical Society (AAS) and the American Institute of Aeronautics and Astronautics (AIAA) welcome you to experience the grandeur of the majestic mountains of Big Sky, Montana (U.S.A.) and the breathtaking views of Yellowstone National Park while sharing your latest research in Astrodynamics. A block of comfortable, spacious suites, condos, and hotel rooms are awaiting you and your family.

With Yellowstone and Grand Teton National Parks immediately to the south, untamed rivers in every adjacent valley, and no major population center within 350 miles, you can experience the romance of a young country, rugged and wild, from a setting that is unquestionably civilized.

The Resort offers beautiful accommodations at the Summit at Big Sky, a 213-room Euro-western luxury condominium hotel offering all the amenities required in a four-star setting. The Huntley Lodge and Shoshone Condominium Hotel offer the ultimate convenience with restaurants, lounges, shops, spas and the conference facility just steps from your room. Big Horn Condominiums and numerous other condominiums in a variety of sizes are within walking distance of the resort center.

Guests dine on excellent cuisine at numerous onsite restaurants and bars. Enjoy the heated swimming pool, tennis courts, and fitness center. Travel down the mountain and experience award winning fare at local restaurants. Peek out your window and see the local wildlife of deer and elk grazing in the fields, or stroll outside at dusk to witness a memorable star filled, crystal clear sky.

Located in Southwestern Montana, Big Sky Resort is situated at the base of Lone Mountain, rising high above the village. Wind your way up the scenic mountain road to the Resort. Explore the Gallatin River, teeming with wild trout and made famous by the film “A River Runs Through It” directed by Robert Redford and featuring Brad Pitt. Take exciting rafting trips on the river or horseback rides through meandering meadows and valleys. Hike up rugged trails (and not-so rugged trails) into untamed territory or ride a mountain bike. On the other hand, relax on the golf course or pamper yourself with a massage or other holistic treatments at the Spa.

TRANSPORTATION

Bozeman airport, located approximately one hour north of Big Sky, is the most convenient airport to the Resort. From Bozeman and the airport, Big Sky is a 45-mile drive through the scenic Gallatin Canyon. Both shuttles and rental cars are available at the airport. Taxi service from the Bozeman airport to the resort is available. Pre-arrangement with Karst Stage (www.karststage.com or by phone at 800-287-4759) at the airport is required. Rental cars are highly recommended so that you can make the most of your trip. Cars may be rented at Bozeman airport or in Big Sky. The Resort encourages exploration of the Meadow Village, Bozeman, West Yellowstone, Yellowstone National Park and other outstanding sites. From Bozeman, take Rte 191 south towards Big Sky, turn right at the Big Sky entrance and continue for fifteen minutes until you reach the entrance for the Resort on your left.

Another excellent option is to arrive in Billings, Montana. Located about 150 miles East of Bozeman, Billings presents itself as a somewhat arid, Western-like area with buttes. As you begin your two (2) hour drive towards Bozeman, you leave the Western countryside and enter rolling, lush green hills reminiscent of Ireland. Continue a little farther and the majestic Rocky Mountains suddenly appear towering above the foothills below. Climb into the mountains and you’ll find yourself in Bozeman, a classic Western town with a 1930s feel to it. You’ll then turn south on Rte 191 and follow the directions above.

Another option, is to fly into West Yellowstone airport, a small airport located to the South of Big Sky. For those adventuresome travelers, arriving at an airport in the Rockies (e.g., Salt Lake City) and a long, yet breathtakingly scenic drive to Big Sky would be worth the time.
