Antelope Canyon, located in northern Arizona, USA, is one of the world's most famous slot canyons, sculpted from soft sandstone by millions of years of flooding and wind erosion. During the monsoon season, torrential rains rush down the narrow passage, creating unique vertical erosion that results in smooth yet hard rock walls at the canyon floor, resembling flowing water. Despite its unassuming exterior, venturing deep into the canyon feels like stepping into a natural art palace. Layer upon layer of rock walls change colour with the light, from orange-red to golden-purple, and every ray of sunlight filtering through the cracks casts a dreamlike and stunning effect. The tour can be selected from either Upper Antelope Canyon or Lower Antelope Canyon

Named one of the top ten best photography locations in the United States by National Geographic, Horseshoe Bend gets its name from the Colorado River's dramatic 360-degree bend, carving out a horseshoe-shaped canyon . Standing atop the red rock cliffs, the azure river meanders through the rugged rock face, creating a spectacular natural arc. The river reflects the orange-red rock layers of the canyon walls, the blue sky, green water, and red earth blending together to form a breathtaking Western landscape. No matter when you visit, Horseshoe Bend's magnificent scenery is unforgettable.

Lake Powell, straddling Arizona and Utah, is an artificial lake formed by the construction of the Glen Canyon Dam on the Colorado River, and is the second largest man-made lake in the United States. Named after 19th-century explorer General John Wesley Powell, the lake is approximately 299 kilometres long with a shoreline stretching over 3,000 kilometres. The stunning scenery, with its interplay of lake and mountain landscapes, and the striking contrast of red rock formations against the azure waters, has made it a popular filming location for films such as *Gravity*, offering truly spectacular views.

The Great Salt Lake, the world's second-largest saltwater lake and North America's largest inland salt lake, is located in western Utah, USA. It is bordered by the Rocky Mountains to the east and desert to the west, and consists of 10 islands. It is also a wildlife sanctuary, attracting millions of migratory birds annually. The lake's salinity is as high as 25%, second only to the Dead Sea, and only a few types of algae that can tolerate extremely high salinity can survive in it.

Yellowstone National Park, the world's first national park, is located in the Los Angeles Mountains, known as the "backbone of America," on a lava plateau between the northern and central Los Angeles Mountains in the western United States. Established on March 1, 1872, it is renowned for its rich wildlife and geothermal resources. Named after the source of the Yellowstone River, the park boasts hundreds of recorded animal species. Native Americans have inhabited the Yellowstone area for at least 11,000 years. Geothermal wonders are its hallmark, and the park's natural landscape is divided into five main areas: the Mammoth Area, the Roosevelt Area, the Canyon Area, the Geyser Area, and the Lake Area, each with its own unique characteristics.

Also known as the Grand Prismatic Spring or the Eye of the Earth, it is located at coordinates 44.524569, -110.837975 in Yellowstone National Park , USA . With a diameter of approximately 100 metres, it is the largest hot spring in the United States and the third largest in the world. It is about 75 to 91 metres wide and 49 metres deep, with a water temperature reaching 85°C, and approximately 2000 litres of 71-degree Celsius water gushing out every minute. It was first discovered by explorers in 1839. The amazing thing about the Grand Prismatic Spring is that the colour of the lake changes with the seasons. In spring, the lake changes from emerald green to a golden orange-red. In the height of summer, the chlorophyll decreases, so the lake displays a vibrant orange, red, or yellow hue. But in the depths of winter, due to lack of sunlight, the water turns a deep, dark green.

Also known as the "Artist's Paint Bucket," it gets its name from its colourful and varied geothermal landscapes and is one of the most distinctive geothermal areas in Yellowstone National Park. It features four typical geothermal phenomena: hot springs, mud pots, fumaroles, and small geysers. Walking along the trails, visitors can get up close to the boiling mud pools, the rising steam from the fumaroles, and the vibrant colours formed by mineral deposits. The entire area resembles nature's palette and is a representative attraction for experiencing Yellowstone's geothermal wonders.

Old Faithful Geyser is a geyser located in Yellowstone National Park, USA , named for its consistent and regular eruptions. It was named during the Washburn-Lanford-Dorn Expedition in 1870, becoming the first named geyser in Yellowstone National Park. Currently, it erupts approximately every 90 minutes, each eruption lasting 4-5 minutes, with water columns reaching over 40 metres high, creating a spectacular sight, and it never stops. The geyser and the adjacent Old Faithful Inn are listed as part of the Old Faithful Historic District.

Morning Glory Pool, located at the end of the Upper Geyser Basin in Yellowstone National Park, is named for the vibrant morning glory-like colours that appear around its edges. It is one of Yellowstone's most iconic hot springs. The water's colour gradually transitions from deep blue to yellow and orange, creating distinct layers under sunlight, making it a highly scenic attraction. Powered by a continuously heating underground spring, Morning Glory Pool boasts extremely high water temperatures. Its unique colour variations, combined with the surrounding steaming landscape, make it a key scenic spot for visitors exploring the Upper Geyser Basin on foot.

Yellowstone Lake, hailed as an "unparalleled high-altitude lake," is the largest lake in Yellowstone National Park and one of the world's highest-altitude lakes. Nestled between mountains and volcanic landscapes, the lake boasts expansive and magnificent scenery, with clear, tranquil waters showcasing Yellowstone's unique high-altitude natural landscape. Influenced by its size, depth, and climate, the lake's appearance changes significantly with the seasons: it often freezes over in winter, while in summer the surface becomes vast and mirror-like, occasionally transforming into a spectacular "inland sea" under the influence of wind. In late summer, the temperature differences create natural stratification in Yellowstone Lake, resulting in rich and delicate layers of colour that, combined with the surrounding mountains and cloud shadows, make it a key attraction for visitors to experience the pristine natural beauty of Yellowstone.

Mud Volcano and Canyon Junction on the Yellowstone Grand Loop , is the second best place in Yellowstone National Park for wildlife viewing, after Lamar Valley . The "valley" refers to a large grassland in front of a forest, with a river flowing through it, making it a suitable place for animals to forage at dawn and dusk. If you keep watch here with binoculars, you can often spot wolves or bears, making it one of the best places in Yellowstone National Park for wildlife viewing.

The Grand Canyon of Yellowstone ranks first among the 90 attractions in Yellowstone National Park and is a must-see . Located between Fishing Bridge and Tower, the Yellowstone Canyon is a rugged canyon formed by the Yellowstone River flowing from Yellowstone Lake over a distance of approximately 38 kilometres. It boasts the most magnificent and beautiful scenery in Yellowstone National Park. The 97-kilometer-long Yellowstone River is the only river in the United States without a dam. Here, the river suddenly becomes rapid, creating two spectacular waterfalls that roar as they plunge into the Grand Canyon.

Artist Point is located in the eastern part of Yellowstone National Park. From Artist Point, you can enjoy the spectacular sight of high and low waterfalls cascading together, as well as the breathtaking natural scenery created by the clear sky, turquoise river, white spray, and tan canyon walls. Artist Point is also the best spot to view the Lower Falls, offering a truly immersive experience of the Grand Canyon of Yellowstone. The approximately 100-meter drop of the falls gives the feeling of a waterfall plunging down a great height, with yellow and red rocks on either side resembling colourful ribbons that shimmer even more brilliantly when sunlight shines upon them.

The Upper Falls was formed by the Yellowstone River eroding softer rocks. Located upstream, the 109-foot-high Upper Falls can be seen from the Upper Falls and Uncle Tom 's Trail, where you can witness the spectacular sight of Yellowstone Falls up close.

The underground hot springs, formed over many years within the Yellowstone National Park ecosystem, contain a variety of natural minerals beneficial to the human body. The beautiful and pleasant environment, combined with the relaxing hot springs, will wash away the fatigue of your journey, allowing you to fully enjoy the most relaxing moments of your trip. Note: Towels can be brought by yourself or rented, with rental fees around US$3-5; swimming costumes must be brought by yourself.

Mammoth Hot Springs is the world's largest known carbonate geothermal spring. Its landscape is dominated by limestone terraces, also known as the hot terrace area, which can be divided into upper and lower terraces. The spring water originates from the Norris Geyser Basin and can reach temperatures of 77°C. Numerous algae thrive in the hot springs, giving them a variety of colours, including brown, orange, red, and green. The continuously flowing hot water cascades down the terraces, creating a magnificent, multicoloured spectacle.

Located at the north entrance of Yellowstone National Park, the archway was personally laid by Theodore Roosevelt, the 26th President of the United States, in 1903, and is one of Yellowstone's most symbolic landmarks. As the only entrance in the park with a formal gate structure, the archway is topped with the famous cross from the Congressional Act—"For the Benefit and Enjoyment of the People"—symbolising the core principles and mission of Yellowstone National Park.

West Thumb Geyser Basin, located on the shore of Yellowstone Lake, was formed 150,000 years ago by a tectonic subsidence. The combination of hot geysers and lake water creates a unique, misty landscape: the steam rising from the hot springs rises amidst the shimmering green waters of Yellowstone Lake, reflecting against the backdrop of blue sky and white clouds, creating a scene unlike any other hot spring area in Yellowstone. This area is essentially a bay of Yellowstone Lake, where many geysers converge. The vents display a variety of colours, some transparent green, others a dark, cement-like black. The numerous vents create a beautiful, fantastical scene.

The park isn't large, but it features giant arches made of deer antlers in the four cardinal directions. The antlers are all hard and durable, making it a shame they aren't used to make deer antler tonics. These antlers aren't from hunting; they're from the large numbers of elk that migrate from the mountains to Jackson's National Elk Sanctuary every winter. In the spring, the antlers naturally shed and are replaced, leaving behind countless treasures after the elk leave.

Established on February 26, 1929, and named after the highest peak in the Teton Mountains, Grand Teton National Park boasts a near-pristine ecosystem. Some prehistoric plants and animals still thrive here, and the oldest rocks have been identified as dating back 2.7 billion years. With its numerous lakes, rivers, and snow-capped mountains, including Jackson Lake and Jenny Lake, the park creates a tranquil world south of Yellowstone. Furthermore, Grand Teton National Park is home to an incredibly diverse array of wildlife, including bison, grizzly bears, black bears, and moose.

The Utah State Capitol, located in Salt Lake City, rivals the scale and design of the US Capitol in Washington, D.C. Its Byzantine-style dome gleams brilliantly in the sunlight. The interior is even more opulent and intricately decorated. The walls are made of polished marble, the ceilings are adorned with exquisite murals, and countless lifelike, finely sculpted figures stand within. Furthermore, given Utah's nickname, the "Honeycomb State," a prominent beehive sculpture stands in front of the building, a must-see for visitors to take photos.
