Things to Know Before Visiting

Arizona is not one hot desert. It spans low desert cities, high pine forests and canyon country, and the best time to visit changes by region. Plan around heat and water first, book permit-controlled places early, and expect long drives between major sights. 1. Arizona is not one climate Phoenix and Tucson sit in the Sonoran Desert, while Flagstaff and the White Mountains are high-elevation pine country with real winters. Sedona sits in between, and Monument Valley and the Grand Canyon are high desert plateau. This is the single biggest planning mistake first-timers make. A July trip works in the mountains but is punishing in Phoenix. A January trip is lovely in Phoenix but can mean snow at the Grand Canyon. Choose your region first, then your dates. 2. Summer heat is a safety issue, not a nuisance In the low desert, summer afternoons can climb well past 100°F. Hiking midday in that heat is how visitors end up needing rescue. Start trails at sunrise, carry far more water than you think you need, and skip exposed hikes after mid-morning. The National Weather Service (weather.gov) publishes Extreme Heat Warnings for Phoenix and other areas. Check them before any outdoor plan. 3. The best months depend on where you’re going For the low desert (Phoenix, Tucson, Saguaro National Park), plan on roughly October through April, as several guides agree. For Flagstaff, the Grand Canyon’s rims and the White Mountains, late spring through early fall is more comfortable. Winter is a good fit for desert cities and a poor fit for mountain driving without a plan for snow and ice. Region Comfortable season Watch out for Phoenix and Tucson Late fall to spring Extreme summer heat Sedona Spring and fall Summer crowds, midday heat Flagstaff and Grand Canyon rims Late spring to early fall Winter snow and road closures Page and Monument Valley Spring and fall Hot summers, cold winter nights 4. Monsoon season brings flash floods Arizona’s monsoon officially runs from June 15 through September 30. Storms can be sudden and local. Slot canyons and dry washes can flood from rain that fell miles upstream, even under a clear sky. Never enter a slot canyon when storms are forecast anywhere in the watershed, and never drive through a flooded wash. Arizona has a “Stupid Motorist Law” that can make you liable for rescue costs if you ignore a barricade. 5. Many famous places need permits, tours or reservations Several of the state’s best-known spots are not walk-up friendly. Antelope Canyon is only visited with an authorized Navajo guide. Havasupai requires reservations through the tribe. The Wave and Coyote Buttes are permit-controlled and highly competitive. Book well before your trip, and check the official source for each site rather than a third-party reseller. 6. Distances are bigger than they look on a map Arizona is large, and the headline sights are far apart. Phoenix to the Grand Canyon South Rim is a drive of several hours, and Monument Valley and Page are further again. Build in time for driving, fuel and stops. A “quick day trip” to the canyon from Phoenix is possible but tiring, so most first-timers do better with an overnight. 7. Altitude and temperature swings are real The Grand Canyon South Rim sits around 7,000 feet, and Flagstaff is higher than that. Visitors coming from sea level can feel headaches or fatigue. Desert air is also dry, so temperatures can swing sharply between day and night. One local writer describes being surprised by how fast the desert shifts from intense heat to chilly temperatures. Pack layers even for a summer trip. azbigmedia 8. Hydration means more than carrying a bottle Dry air pulls moisture from you fast, and you often don’t notice sweating. Start drinking water before you feel thirsty, add electrolytes on long outings, and keep extra water in the car. Note that dark car seats and seatbelt buckles can burn skin in summer, so use a sunshade. 9. Cell service disappears quickly Coverage is solid in cities and along major highways, then drops out in canyons, reservations and backcountry roads. Download offline maps for Google Maps or your hiking app before you leave town. Tell someone your route if you’re heading onto remote roads, and keep your fuel tank well above half. 10. Arizona does not observe daylight saving time (mostly) Most of Arizona stays on Mountain Standard Time all year. The Navajo Nation, which covers parts of northern Arizona including areas near Monument Valley, does observe daylight saving time. During summer, a tour booked at a Navajo-run site can be an hour off from the time on your phone. Confirm tour times in local time when you book.

It depends on the region. Spring and fall suit most of the state, while summer works best in the high country and winter suits the desert cities. Is Arizona too hot to visit in summer? The low desert is very hot, but the mountains and rims are far cooler. Visit Flagstaff or the White Mountains instead of Phoenix if you travel in July. How many days do you need in Arizona? Four to five days covers Phoenix, Sedona and the Grand Canyon. Add more days for Page, Monument Valley or Tucson. Do I need a permit for Antelope Canyon or Havasupai? Yes. Antelope Canyon requires a guided tour with an authorized operator, and Havasupai requires reservations. Always book through the official source. Does Arizona have daylight saving time? Most of the state does not, but the Navajo Nation does.

The biggest things to know before visiting Alaska are that it is enormous, expensive and wild. Pick two or three regions rather than the whole state. Travel between mid-May and mid-September for the easiest conditions. Choose summer for midnight sun or winter for northern lights, since you rarely get both. Carry bear spray, dress in layers, and check Denali’s road status before booking. 1. Alaska is far bigger than you think Alaska is the largest US state, so a two-week road trip will not cover it. One resident who has lived there for over two decades warns visitors not to try to see all of Alaska in a week. Spending less time in the car leaves more time to explore. divergenttravelersYahoo News Tour operators say all the regions could fit into two to three weeks, but many visitors choose two or three key areas for a shorter trip. A realistic first trip might pair Anchorage with the Kenai Peninsula, or Fairbanks with Denali. Decide which parts of the state matter most to you, then build the route around them instead of squeezing in everything. intrepidtravel 2. The season is shorter than the calendar suggests Mid-May to mid-September is the key tourist season, and the weather can turn quickly even at the height of summer. May and September, the shoulder season, offer a different perspective with fewer crowds. Winter has its own appeal if you want to see the northern lights or the Iditarod. Everything you need to know about travel in Alaska +2 Season Best for Trade-off Mid-May to mid-September Tours, wildlife, long days Peak prices and crowds May and September Quieter trips, lower demand Faster-changing weather Winter Aurora, snow sports Short days, cold 3. You usually have to choose between midnight sun and northern lights Summer’s endless light is a highlight, but it hides the aurora. Fairbanks tourism lists midnight sun season as April 22 to August 20, and aurora season as August 21 to April 21. In summer, the sky never gets truly dark, so geomagnetic activity goes unseen. explorefairbanksloudavymkrokem Plan around one or the other. Choose June or July for hiking, fishing and late-night light. Choose September through March for aurora viewing, ideally with at least three nights in Fairbanks so one clear night is likely. Even then, no guide can promise a clear sky, so build in spare nights. 4. Denali’s road is not fully open yet (check before you book) This is the planning trap of 2026. A landslide closed the 92-mile Denali Park Road in 2021, and the park said the closure at mile 43 remains in place through summer 2026. Buses have been stopping at East Fork, around mile 43. deeparrivalafar There is good news. The roughly 475-foot Pretty Rocks Bridge is now complete, and hikers and cyclists can already cross it. Buses are expected to run the full road again in 2027, and 2027 bus and campground reservations open December 1, 2026. If you want Wonder Lake views, plan for 2027 and reserve early. For this year, confirm current conditions on the National Park Service site. frommersfrommers 5. Bears and moose are serious business Wildlife is why people come, and also why rules exist. In Denali, stay at least 300 yards (275 meters) from bears and 25 yards from all other animals. Moose weigh up to 1,600 lbs and will charge anything they see as a threat. npsnps Animal Minimum distance (Denali rule) Bears 300 yards Moose and other animals 25 yards Carry bear spray where you can reach it quickly, never run from a bear, and aim low if one comes within about 20 feet. On a bus, keep spray stowed in your pack. Practice with the holster before your trip, because a stressful encounter is a bad time to read instructions. nps 6. Getting around takes more planning than you expect Alaska’s road network is thin. Many towns and natural wonders can only be reached by boat or floatplane, so add time and cost for transport. Fuel stations can be several hundred kilometres apart, so fill up when you can. ytravelblogintrepidtravel Rail is a good alternative: the Alaska Railroad carries passengers between Fairbanks and Seward, including Anchorage. If you rent a car, read the agreement. Some roads, such as the Denali or Dalton Highway, are often off-limits to rentals. Main highways are paved but can be rough from potholes, so allow extra drive time. npsyahoo 7. Costs add up quickly Plan your budget before you arrive. Most things in Alaska cost more than in the lower 48, so do not assume you can buy gear or supplies once you get there. Flights to small towns, tours, lodging and groceries all cost more, and peak-season rooms book out early. divergenttravelers Practical ways to save: travel in the shoulder months, rent a car or camper only for the legs you need, and pack key items from home. Compare tour prices carefully, because some cheaper options cover the same ground as pricier ones. 8. Layers beat any single jacket (and yes, you can get sunburned) Weather varies by region. The state has five distinct climate zones, and dressing in layers is the key to handling whatever weather arrives. In Denali, snow can fall nearly any month of the year. npsnps Pack a waterproof shell, warm mid-layers, a hat and sturdy shoes. Add sunscreen too. Long summer days and glacier glare mean you can get sunburned in Alaska. A sleep mask also helps when the sun barely sets. divergenttravelers 9. Help can be far away, so tell someone your plan Remote places have limits. Even the entrance of Denali is several hours from the nearest hospital, and most of the park is trail-less. Cell coverage cannot reach every square mile of such a large state. npsdivergenttravelers Before you head out, make sure someone knows your itinerary, check the forecast, and turn back when conditions change. Know your limits, and choose guided trips for glaciers, rivers and backcountry flights if you are new to
