Magnificent, peaceful. Just two words to describe the scenic regions of Utah in the Mountain West of the United States. Now, our office offers fabulous, five-day outdoor packages to the state for the adventurous.
    On the first day of your tour, visit the capital of historic Salt Lake City, Temple Square, home to the world-famous Mormon Tabernacle Choir, and other local historical sites.
    Then, your tour will take you on a four-day adventure of a lifetime to central and southern Utah where you will hike and backpack through Arches National Park, Goblin Valley, and Bryce National Park. You’ll also explore the magical world of Little Wild Horse Canyon. This very narrow, winding chasm, with its steep walls on either side of you, will leave you in amazement knowing that it was formed from rushing water and erosion over millions of years.
    You’ll also hike and scramble up to remote Indian ruins, study their history along the way, and learn how to respect and preserve the sites and wildlife you encounter. You also learn the basics in rappelling — techniques designed specifically for the amateur climber.
    The price of your package includes local transportation in Utah, one-night’s lodging in a four-star hotel in Salt Lake City, hiking and camping gear, two meals a day, and your professional tour guide. Transportation from your point of origin is not included. Contact our office between 8 a.m. and 5:30 p.m. for more information and current availability on this wilderness trek, and reservations must be made thirteen days in advance. Let us show Utah like no one else can.
