B	bicycling Bicycling is permitted on public roads, both paved and dirt. There are no bicycle paths along roads. Bikes are prohibited on backcountry and nature trails.
	bus tours Several companies offer tours of the park by bus or van. Contact your travel agent for additional information.
C	campfires Campfires are permitted in campgrounds and in picnic areas where fire grates are provided. Campfires are not allowed in the backcountry. Collecting vegetation, living or dead, is prohibited, so bring firewood.
	climate Days are typically clear with less than 25 percent humidity. Temperatures are most comfortable in the spring and fall, with an average high/low of 85°F and 50°F respectively. Winter brings cooler days, around 60°F, and freezing nights. It occasionally snows at higher elevations. Summers are hot, over—sometimes well over—100°F during the day and not cooling much below 75°F until the early hours of the morning.
	commercial filming When filming or photography involves advertising a product or service, the use of models, sets, props, or the use of a restricted site, a film permit is required.
D	day-use and restricted areas Some areas within the park are privately owned; others protect wildlife or historical sites. Entering these areas is prohibited. Day-use areas are set aside to protect sensitive populations of wildlife. They are closed from dusk to dawn.
	dehydration It is easy to become dehydrated in arid desert environments. Even if you only plan to drive through the park, you should have some water with you. If you are going to camp, we recommend one gallon of water per person per day. If you are going to be hiking or biking, you will want to take along two gallons per person. Drink the water and do not economize. When the water is half gone, it is time to turn back.
E	emergency phones In an emergency call San Bernardino Dispatch at 909-383-5651. Call collect. Pay phones are located at the visitor center in Twentynine Palms and at Black Rock Campground. You can find pay phones in the town of Joshua Tree and at Chiriaco Summit (12 miles southeast of Cottonwood). Emergency-only phones are located at the Indian Cove ranger station and at Intersection Rock parking, adjacent to Hidden Valley Campground.
	entrance fees Admission to the park is $10 per vehicle and is good for seven consecutive days. A Joshua Tree Pass may be purchased for $25 and a National Parks Pass, which is good for all National Park Service sites, costs $50. Both are good for 12 months. A Golden Age Pass may be purchased by any U.S. citizen 62 or older for $10, and it is good for life.
F	firearms and weapons Firearms, including fireworks, traps, bows, BB guns, paint-ball guns, and slingshots are not allowed in the park.
	food, lodging, services There are no concessions within the park. However, surrounding communities can fulfill most visitor needs. Contact local chambers of commerce for information.
G	getting to the park The park is located about 140 miles east of Los Angeles via I-10. Entrances to the park are located off CA HWY 62 (Twentynine Palms Highway), at the towns of Joshua Tree and Twentynine Palms. A third entrance is located about 25 miles east of Indio off I-10.
H	horses For those with horses, riding is a pleasant way to experience the park. Because of the special requirements for horses in this environment, care should be taken in planning your trip. The lack of available drinking water is both a challenge and a limitation.
I	international visitors Information is available at visitor centers and entrance stations in Dutch, French, German, Italian, Japanese, and Spanish.
K	keep wildlife wild Feeding coyotes, squirrels, and other animals weans them from their natural food supplies and turns them into dangerous creatures as they lose their fear of humans and become agressive.
L	leave no trace During your visit please pick up trash around campgrounds and trails. Your actions will inspire other park visitors.
	lost & found Report lost, and turn in found, items at any visitor center or ranger station. Lost articles will be returned if found.
O	off-road driving Vehicles, including bicycles, are prohibited off established roads. The desert ecosystem is fragile. Off-road driving and riding creates ruts, upsetting delicate drainage patterns, compacting the soil, and leaving visual scars for years. Plants are crushed and uprooted. Wildlife shelters are destroyed, and food and water supplies are altered or obliterated.
P	parking Park roads, even the paved roads, are narrow, winding, and have soft, sandy shoulders. Accidents occur when visitors stop along the road to admire a view or make a picture. There are many pullouts and parking lots, so wait until you get to one before stopping.
	pets While pets are allowed in the park, their activities are restricted. They must be on a leash at all times, they are prohibited from trails, and they must never be left unattended—not even in a vehicle.
	potable water Water is available at the visitor center in Twentynine Palms, at Black Rock and Cottonwood campgrounds, at the entrance station south of Joshua Tree, and at the Indian Cove ranger station.
S	stay out and stay alive Mining was an important activity in this area and numerous mining sites can be found within the park. If you choose to visit them, use extreme caution and do not enter old mine workings.
T	take only pictures Over 1.25 million people visit Joshua Tree National Park each year. If each visitor took only one rock or one branch from a bush, the park, our national heritage, would soon be gone. Removal, disturbance, destruction, or disfigurement of anything in the park is unlawful.
	trash Our dry desert climate cannot quickly decompose such things as orange peels, apple cores, egg shells, and other picnic remains. Loose paper blows into bushes creating an unsightly mess, and plastic six-pack rings can strangle wildlife. Dispose of your trash in a responsible manner and recycle whatever you can.
V	vehicle laws Park roads are narrow and winding. Some areas are congested. Speed limits are there for your safety and wellbeing. State and federal vehicle laws apply within the park.
	visitor activities The park offers visitors a variety of activities from rock climbing to wildflower viewing, to ranger-led programs.
W	wildflowers Spring blooming periods vary with elevation, temperature, and the amount of moisture in the soil.
	wildlife viewing It is a thrill to see wild animals in the park, but remember: this is their home and they should not be disturbed. This includes the use of artificial light for viewing them.
Y	you are responsible You are responsible for knowing and obeying park rules. Check at visitor centers, at entrance stations, and on bulletin boards to find out what they are. When in doubt, ask a ranger.
