Kinnso has meticulously compiled a travel blueprint for 2026, highlighting the most exciting destinations to explore, from the sun-kissed coastal highways of the West to the historically rich cities of the East, and the tropical paradise of Hawaii. Whether you're a first-time traveler to the U.S. or a seasoned explorer seeking in-depth experiences, follow this comprehensive guide to craft your perfect dream itinerary!

When it comes to classic travel experiences in the United States, nothing quite compares to a "road trip." If you dream of the freedom of driving with the wind in your hair, the American West should be your top choice. The "California Highway 1," which stretches from San Francisco along the coastline to Los Angeles, is renowned as one of the most beautiful coastal roads in the world. Along the way, you'll encounter the enchanting Big Sur and the fairytale-like town of Carmel-by-the-Sea. With steep cliffs on one side and the azure Pacific Ocean on the other, the breathtaking scenery will surely have you reaching for your camera nonstop.

For travelers who enjoy unique rock formations, embarking on a journey from Los Angeles to the rugged desert is an excellent choice. You can plan a three-day trip to Joshua Tree National Park and unwind in the desert oasis of Palm Springs. If you have extra time, you definitely shouldn't miss the classic "Grand Circle" route, which includes the Grand Canyon, Antelope Canyon, and Horseshoe Bend. Witnessing the deep canyons carved by the Colorado River over millions of years is an awe-inspiring experience that no photograph can truly capture.

When traveling in the western United States, renting a car is an essential mode of transportation. It is advisable for travelers from Hong Kong and Taiwan to obtain an international driving permit before departure and to purchase full insurance when booking a vehicle. If you are planning a trip along California's Highway 1, it is highly recommended to drive from north to south (from San Francisco to Los Angeles), as this allows the vehicle to stay on the seaside, making it convenient to stop at viewpoints for photos at any time.

The United States National Park System is renowned worldwide, serving as a paradise for outdoor enthusiasts. Located in California, Yosemite National Park is famous for its granite cliffs, spectacular waterfalls, and giant sequoia trees. Whether you plan to challenge yourself by climbing the iconic Half Dome or leisurely cycling through the valley while inhaling the fragrant air filled with phytoncides, this park provides an escape from the hustle and bustle of city life. Camping under a starry sky in an area free from light pollution is an invaluable experience.

If you want to witness geothermal wonders and a rich array of wildlife, then Yellowstone National Park, which spans the Midwest, should definitely be on your must-visit list. As the first national park in the world, it is home to the famous Old Faithful geyser and the vividly colored Grand Prismatic Spring. While driving through the park, you might encounter herds of American bison, elk, or even black bears, all showcasing the raw charm of nature.

If you plan to visit three or more national recreation areas, it is advisable to purchase the "America the Beautiful Pass." The fee is $80 per vehicle (approximately HKD 625 / TWD 2,500), making it a great deal. Additionally, accommodations and campsites within national parks often fill up six months in advance, so be sure to plan and book early. The temperature in mountainous areas can vary greatly between day and night, so even in summer, be prepared with warm clothing.

If you have a penchant for urban vibrancy and rich cultural history, the East Coast of the United States will not disappoint you. New York City, known as the crossroads of the world, pulsates with endless energy. You can spend an entire day strolling through Central Park, then head to the Metropolitan Museum of Art for an artistic immersion in the afternoon. In the evening, walk across the Brooklyn Bridge to admire the enchanting skyline of Manhattan, and cap off your day with a world-class musical on Broadway. The culinary scene here is incredibly diverse, offering everything from street-side hot dog stands to Michelin-starred restaurants.

Located about a four-hour drive from New York, Boston exudes a distinct academic and historical atmosphere. Walking along the brick-paved Freedom Trail, you can truly immerse yourself in the historical context of America's fight for independence. After crossing the Charles River into Cambridge, take a leisurely stroll through the campuses of Harvard University and the Massachusetts Institute of Technology, where the rich academic environment is palpable. Don’t forget to savor Boston's most famous dishes: the rich clam chowder and the sweet lobster roll, which are sure to delight your taste buds.

Unlike the West Coast, major cities on the East Coast (especially New York) experience heavy traffic and high parking fees, so it is highly recommended to rely entirely on public transportation. While New York's subway system may be old, it is extensive and well-connected. For intercity travel, you can opt for the cost-effective Amtrak trains or long-distance buses like FlixBus. If you're looking to save money on Broadway musicals, you can try your luck at the TKTS ticket booth in Times Square on the day of the show to purchase discounted tickets.

For families seeking a fun getaway or friends in search of adventure, Florida is an unmissable vacation destination. Orlando, known as the "Theme Park Capital of the World," boasts the magnificent Walt Disney World and the Universal Orlando Resort. Here, you can snap a photo with classic cartoon characters in the Magic Kingdom or enjoy an authentic Butterbeer in the Wizarding World of Harry Potter, allowing your inner child to run wild.

After leaving the amusement park, you can head south all the way to the end of the Florida Keys—Key West. This vibrant destination is infused with Cuban charm and a laid-back island vibe. Here, you can enjoy snorkeling, sunbathe on pristine white sandy beaches, or gather with travelers from around the world at Mallory Square to witness one of the most stunning sunsets over the ocean in the United States.

Florida experiences extremely hot and humid summers, often accompanied by afternoon thunderstorms. The ideal travel season is actually from fall to spring. To enhance your experience at the theme parks, it is highly recommended to purchase tickets in advance that include fast pass options, such as Disney's Genie+ or Universal Studios' Express Pass, which can save you several hours of waiting in line. Staying at an official park hotel also grants you the privilege of early park entry, making it a worthwhile consideration.

When it comes to ultimate vacation destinations away from the hustle and bustle, Hawaii consistently ranks at the top. Whether it's a honeymoon for couples or a family getaway, the Aloha spirit of Hawaii instantly helps you unwind. For first-time visitors to Hawaii, Oahu is the most well-rounded choice. It boasts the famous Waikiki Beach, the breathtaking views from Diamond Head, and world-class shopping malls, perfectly blending nature with modern living.

If you prefer a more pristine natural environment and tranquility, Maui is the ideal choice. You can challenge yourself by driving along the Road to Hana, famously known as the "Road to Paradise," where you can admire tropical rainforests and countless waterfalls along the way. Alternatively, you can head to Haleakala Volcano in the early morning to witness the breathtaking sunrise above the sea of clouds. The snorkeling conditions here are exceptional, and if you're lucky, you might even swim alongside green sea turtles.

Transportation between the islands of Hawaii primarily relies on inter-island flights (such as Hawaiian Airlines). The cost of accommodation and living expenses in Hawaii tends to be higher than in mainland America, so it is advisable to allow for a bit more flexibility in your budget planning. Renting a convertible car to tour the island is a highly popular experience; however, be sure to never leave any valuables in plain sight inside the vehicle when you step away, as this may attract the attention of thieves.

When planning a trip to the United States, it's important to pay attention to several key details, despite the diverse and rich itinerary. First and foremost is the visa issue. Holders of Hong Kong Special Administrative Region passports and Taiwan passports typically need to apply for an Electronic System for Travel Authorization (ESTA) online in advance for tourism purposes. Be sure to complete this process early and carry proof with you at all times. Secondly, the tipping culture in the United States is quite significant. When dining at restaurants, taking taxis, or enjoying hotel services, it is customary to tip between 18% to 22% of the total bill. This practice differs greatly from habits in Hong Kong and Taiwan, so be sure to factor tips into your travel budget. Lastly, due to the extremely high medical costs in the United States, it is essential to purchase comprehensive travel insurance that covers unexpected illnesses and accidents abroad before you depart. This will ensure that you can enjoy your trip with peace of mind.

Are you ready to pack your bags? The vast expanse of the United States is brimming with endless possibilities and surprises. No matter which route you choose, you are bound to create unforgettable memories. Start planning your American adventure for 2026 now!
