Arches National Park  is a United States National Park that is located in Utah's Canyon Country near the town of Moab. It is home to the world's greatest concentration of natural arches, including the famous Delicate Arch that was seen all over the world during the 2002 Salt Lake City Winter Olympics.
Arches National Park preserves over 2000 natural sandstone arches. This area contains the largest concentration of arches found any where in the world, including the world-famous Delicate Arch as seen on the Utah state license plate, in addition to a variety of unique geological resources and formations. In some areas, faulting has exposed millions of years of geologic history.The extraordinary features of the park, including balanced rocks, fins and pinnacles, are highlighted by a striking environment of contrasting colors, landforms and textures.
Throughout the park, rock layers reveal millions of years of deposition, erosion and other geologic events. These layers continue to shape life in Arches today, as their erosion influences elemental features like soil chemistry and where water flows when it rains. Arches is located in a "high desert," with elevations ranging from 4,085 to 5,653 feet above sea level.
In 1923 Alexander Ringhoffer, a prospector, wrote the Rio Grande Western Railroad in an effort to publicize the area and gain support for creating a national park. Ringhoffer led railroad executives interested in attracting more rail passengers into the formations; they were impressed, and the campaign began. The government sent research teams to investigate and gather evidence. In 1929, President Herbert Hoover signed the legislation creating Arches National Monument, to protect the arches, spires, balanced rocks, and other sandstone formations. In 1971 Congress changed the status of Arches to a National Park, recognizing over 10,000 years of cultural history that flourished in this now famous landscape of sandstone arches and canyons.
To many, the most outstanding natural features of Arches are the park's geologic formations. Over 2,000 catalogued arches range in size from a three-foot opening (the minimum considered to be an arch), to Landscape Arch which measures 306 feet from base to base. Towering spires, fins and balanced rocks complement the arches, creating a remarkable assortment of landforms in a relatively small area.
Two unusual natural features common in Arches intrigue both scientists and visitors: cryptobiotic soil and potholes. Cryptobiotic soil is a living groundcover that forms the foundation of high desert plant life.
Potholes are naturally occurring basins or pools in sandstone that collect rainwater and wind-blown sediment. These potholes harbor organisms that are able to survive long periods of dehydration, and also serve as a breeding ground for many desert amphibians and insects. Both of these communities are very vulnerable to human impacts.
 Flora and fauna
The plants and animals in Arches have many adaptations that enable them to survive these conditions. Some species are found only in this area. The diversity of organisms reflects the variety of available habitat, which includes lush riparian areas, ephemeral pools, dry arroyos, mixed grasslands and large expanses of bare rock. There are many jackrabbits that live here.
Southeast Utah is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over 40 °F (22 °C) in a single day. The temperate (and most popular) seasons are spring (April through May) and fall (mid-September through October), when daytime highs average 60 to 80°F (15 to 27°C) and lows average 30 to 50°F (-1 to +10°C).
Summer temperatures often exceed 100°F (38°C), making strenuous exercise difficult. Late summer monsoon season brings violent storm cells which often cause flash floods.
Winters are cold, with highs averaging 30 to 50°F (-1°C to +10°C), and lows averaging 0 to 20°F (-18 to -7°C). Though large snowfalls are uncommon (except in nearby mountains), even small amounts of snow or ice can make local trails and roads impassable.

 Precautions Before You Visit
Stay on the path: Throughout the park and the Southwestern national parks, you will see warnings about Cryptobiological soil. Foot prints erode the soil and destroy years of growth.
Leave your dog at home: . As the climate indicates, there is extreme heat in the summers. Perhaps more importantly, the environment is not supportive of domesticated pets. There are reasons that there are still 1000 year old corn cobs in archeological sites, items do not deteriorate like they might in your back yard. Cactus and Fido do not make for good bedfellows.
Leave only your footprints, take only photographs: Do not take rocks or anyother type of souvienier from the park. Allow your grandchildren's grandchildren to see the park as you see it when you visit it. Throughout the southwest, you will walk right next to archeological sites. These are rapidly disappearing as people take just one little thing back home.
 Get in
 By air
Moab's Canyonland Field Airport  has daily service to Denver on Great Lakes Airlines . The closest major airport is Salt Lake City International Airport  about a 4 hour drive away by way of Interstate 15 and US Highway 6/191.
 By car
The entrance to Arches National Park is located 5 miles north of Moab along US Highway 191.
 By bus
Most visitors see Arches National Park on their own, driving automobiles, riding bikes or hiking. However, there are a few privately operated tour companies authorized by the National Park Service to provide visitors with guided trips into the park:
Park entrance fees are $10 for private vehicles and $5 for individuals on foot, bike, or motorcycle. These fees allow entrance for seven days. Alternatively, the $85 Multi-Agency pass allows entry pass, amongst others, to all national park areas for one year. It also allows entrance to parks of other agencies. The $50 National Park Pass, which allowed entry to all national park areas for one year was discontinued by the national parks service in 2007. If the entrance booth is not manned, there is an electronic kiosk to pay the entrance fee and receive a receipt to place on your vehicle's dashboard.
 Get around
 By car
A car is the most common way of exploring the park; most visitors will drive to sites and then take short walks to view the amazing geologic formations of the park. There are several four-wheel drive roads in the park's backcountry that may appeal to those with appropriate vehicles.
 By foot
There are numerous trails throughout the park, providing an alternative means of travel for those not wanting to spoil the nature experience with a vehicle. Hiking at or around sunrise (5-6 am) can provide a less crowded experience and easier parking.
 By bike
Although the summer heat can make a bike a masochistic way of viewing the park, in cooler months it can be a popular option. Though there are no bike lanes and traffic can be heavy at times, biking the scenic drive is a great way to see the park. The Salt Valley and Willow Springs roads are less traveled but are more suited to mountain bikes due to washboards, deep sand and other obstacles. Bicycles are only permitted on roads: there is no single track or trail riding in the park. When biking on the main road, please use caution and ride single file on the edge of the lane.
There is a cooperating association sales outlet in the visitor center that offers books, maps, postcards, posters, and a variety of other educational and interpretive items. For a larger selection, the town of Moab has everything necessary to satisfy your shopping needs.
There is no food available within the park. There is a water fountain at the parking area near the Devil's Garden Trailhead. The nearby town of Moab offers a vast number of restaurants, convenience stores, and grocery stores.
There is no lodging within the park, although the nearby town of Moab has an enormous number of hotels to choose from.
There is only one campground within the park, and reservations are highly recommended. Outside of the park the Bureau of Land Management (BLM) operates several campsites (see www.blm.gov/utah/moab/rec-frame.html).
Arches is a relatively small park, with very few areas far enough from roads to qualify as backcountry. Outside the developed areas there are no designated trails, campsites, or reliable water sources.
In order to backpack in Arches, you must obtain a free backcountry permit at the visitor center. The maximum group size is twelve, but smaller groups are strongly recommended to reduce impacts. Permits may not be reserved in advance. Backpackers should know how to navigate with a topographic map, recognize safety hazards and practice low-impact camping specific to the high desert. Primary safety considerations include steep terrain, loose rock, lightning, flash floods, and dehydration.
Pets may not accompany groups in the backcountry.
 Stay safe
Summer temperatures can reach or exceed 110°F (43°C), so it is important to carry (and consume) enough liquid to keep you hydrated. One gallon of water per person per day is recommended. When hiking on open rocky areas, be aware that lightning is a danger during storms. Also, the dry sandstone-dominated terrain is susceptible to flash floods during thunderstorms. The most intense thunderstorms occur from July through September, during monsoon season.
Many of the formations within the park are sandstone and can easily crumble when climbing. Numerous individuals must be rescued each year after they scale a formation and then discover that they cannot easily get back down; know your limitations, and be aware that it is usually easier to climb up a formation than it is to climb back down.
