Why It Wows: Utah has an embarrassment of riches when it comes to otherworldly rocky landscapes, but the geologic amphitheater that is Cedar Breaks National Monument steals the show (entrance fee from $15). Rich mineral deposits in the cliffs and hoodoos resemble a sweeping sunset of orange, yellow, red, and purple. During July and early August, some 250-plus species of wildflowers bloom, creating a Technicolor landscape.
Adventure Intel: Tucked in the mountains 20 miles east of Cedar City, this three-mile-long cirque gets a sliver of the foot and vehicle traffic seen at nearby Bryce Canyon and Zion National Parks but offers just as many options for outdoor lovers. Because it’s located at an elevation of 10,000 feet, summer temperatures are comfortable, with highs hovering around 70 degrees.
Hikes range from the ADA-compliant, two-mile round-trip Sunset Trail, which skirts part of the rim overlooking the amphitheater, to the 12.8-mile Rattlesnake Creek Trail, a two- to three-day hike in the Ashdown Gorge Wilderness that drops into the amphitheater.
2. Peter Lougheed Provincial Park, Alberta
Why It Wows: Often referred to as Banff National Park’s lesser-known sister, this 76,800-acre patch of wilderness in the Canadian Rockies is the epitome of postcard perfection, with its snow-crowned peaks, sparkling alpine lakes, glacial streams, and evergreen valleys. In autumn the park is most dazzling, when larches’ needles turn gold and the trees are reflected in the lakes.
Adventure Intel: Peter Lougheed, 85 miles southwest of Calgary, is one of Canada’s most accessible parks, with multiple barrier-free trails wide enough to accommodate wheelchairs (entrance fee from $12).
Stay at William Watson Lodge, fresh off a $6 million renovation (from $21 for a campsite; from $31 for a cabin). It overlooks Lower Kananaskis Lake, prioritizes people with disabilities and seniors, and features 22 accessible cottages, plus 13 campsites, and 11 miles of accessible trails on-site.
3. Lefkada Island, Greece
Why It Wows: Sea and sky meld together in an ombré of blues on this under-the-radar Ionian isle. Chalky cliffs and white-sand and pebble beaches also woo those in the know, but the interior is just as wondrous, filled with a dense forest of ancient oak, dramatic gorges, and tumbling waterfalls.
4. Las Coloradas Lagoon, Yucatán, Mexico
Why It Wows: These glimmering cotton-candy-colored lakes pop against a backdrop of powdery white-sand beaches and pastel blue skies within the protected reserve of the Ría Lagartos Biosphere. The lagoons get their blush tint from the plankton, red algae, and brine shrimp that thrive in the super salty waters.
5. Rio Sucuri, Brazil
Why It Wows: Eleven miles outside Bonito, the self-declared ecotourism capital of Brazil, you’ll find Rio Sucuri, whose Avatar-blue waters are considered some of the clearest on the planet. Set against the lush jungle, its spring-fed waters glow a surreal electric blue.
Adventure Intel: Bonito is located in the central-western state of Mato Grosso do Sul. It takes some effort to reach. After an approximate two-hour nonstop flight from São Paulo to Campo Grande, it’s a three-and-a-half hour drive to Bonito; from there, the access point to Rio Sucuri is another 12 miles away.
Boyrá Pousada and Hotel Esmeralda (from $160 and $160, respectively) are both great boutique stays around 50 minutes away, set on the banks of the Rio Formoso, another pristine, spring-fed waterway.
