1. Yellowstone National Park, Wyoming

Must-See Attractions

As America’s first national park, Yellowstone offers an unparalleled concentration of geothermal wonders and wildlife viewing opportunities. Old Faithful, the park’s most famous geyser, erupts approximately every 90 minutes, shooting thousands of gallons of boiling water up to 185 feet into the air. The Grand Prismatic Spring, with its vivid rainbow colors created by heat-loving bacteria, appears almost otherworldly. Don’t miss the Grand Canyon of the Yellowstone, where the Yellowstone River plunges over two spectacular waterfalls, creating a dramatic gorge painted in vibrant yellows and reds.

Best Hiking Trails

• Mount Washburn Trail (6.2 miles round-trip): Offers panoramic views of the park and potential wildlife sightings
• Fairy Falls Trail (5 miles round-trip): Leads to a 200-foot waterfall and provides an elevated view of Grand Prismatic Spring
• Mystic Falls Loop (3.5 miles): Features a beautiful waterfall and geothermal features with moderate elevation gain
• Storm Point Trail (2.3 miles): An easy lakeside hike with excellent wildlife viewing opportunities

Ideal Visiting Seasons

Summer (June-August) offers the most accessible experience with all roads and facilities open, though crowds are at their peak. For fewer visitors while still enjoying good weather, consider May or September. Winter transforms Yellowstone into a snow-covered wonderland, with opportunities for snowshoeing, cross-country skiing, and unique wildlife viewing, though access is limited to snowmobiles and snow coaches in many areas.

2. Grand Canyon National Park, Arizona

Must-See Attractions

The Grand Canyon defies description – this colossal chasm stretches 277 miles long, up to 18 miles wide, and over a mile deep. The South Rim offers the most accessible viewpoints, including Mather Point, Yavapai Observation Station, and Desert View Watchtower. For a more remote experience, the North Rim (open May-October) provides equally stunning vistas with significantly fewer crowds. Watching the sunrise or sunset from either rim is an essential experience, as the changing light transforms the canyon walls into a kaleidoscope of colors.

Best Hiking Trails

• Bright Angel Trail: The park’s most popular trail offers shade, water stations, and spectacular views
• South Kaibab Trail: Steeper but less crowded with panoramic vistas at Ooh Aah Point and Skeleton Point

• North Kaibab Trail: The only maintained trail into the canyon from the North Rim

Ideal Visiting Seasons

Spring (March-May) and fall (September-November) offer ideal temperatures for hiking and exploring, with fewer crowds than summer. Summer brings intense heat in the canyon bottom (often exceeding 100°F), making hiking dangerous during midday. Winter provides a unique, serene experience on the South Rim with possible snow, while the North Rim closes from mid-October to mid-May due to heavy snowfall.

3. Yosemite National Park, California

Must-See Attractions

Yosemite Valley forms the heart of this iconic park, where towering granite monoliths, cascading waterfalls, and ancient sequoias create an unforgettable landscape. El Capitan and Half Dome rise dramatically from the valley floor, challenging rock climbers from around the world. Yosemite Falls, North America’s tallest waterfall at 2,425 feet, thunders most impressively in spring. Tunnel View provides the classic panorama of the valley, while Glacier Point offers sweeping vistas from above. Don’t miss the giant sequoias in Mariposa Grove, some over 2,000 years old.

Fall offers pleasant temperatures and fewer visitors, while winter transforms the valley into a quiet wonderland, though many high-elevation roads close due to snow.

4. Zion National Park, Utah

Must-See Attractions

Zion’s massive sandstone cliffs, colored in shades of cream, pink, and red, rise thousands of feet above the lush valley floor. The Narrows, where the Virgin River has carved a spectacular gorge with walls a thousand feet tall and the river sometimes just twenty feet wide, offers one of the park’s most unique experiences.
