Western Parks
One of the world's greatest reservoirs of natural landscapes — Grand Canyon (1,829 m deep), Yellowstone (the world's first national park, 1872), Yosemite (sequoias, El Capitan, Half Dome), Zion (vermilion canyon), Bryce (red hoodoos), Monument Valley (iconic American Western mesas), with Las Vegas as an oversized base camp.
The Western American Parks form one of the world's largest natural landscape reservoirs — unique concentration of canyons, mesas, geysers, sequoia forests, deserts and mountains spread across 5 states (Utah, Arizona, Nevada, Wyoming, Montana) covering the equivalent of all France. This region inspired the very concept of national park (Yellowstone created in 1872 by President Ulysses S. Grant, world's first), forging American Old West mythology (Western, Route 66, Plains Indians), and remains today the ultimate US road trip pilgrimage.
The region organises around several complementary sets. Las Vegas (Nevada, 660,000 inhabitants, 2.3 million metro, 40 million visitors/year) is the oversized and improbable base camp — artificial casino-city in the Mojave desert, the Strip (Las Vegas Boulevard) aligns 4.3 km of mega-resort hotel-casinos thematic (Bellagio fountains, Venetian canals, Caesars Palace antiquity, Mirage volcano, Wynn luxury, MGM Grand, Mandalay Bay, Aria, Cosmopolitan). Cirque du Soleil shows, resident concerts (Adele, U2, Bruno Mars), boxing (MGM Grand Garden Arena), NHL (Vegas Golden Knights T-Mobile Arena), NBA from 2026 (Vegas Aces WNBA already), Formula 1 (Las Vegas Grand Prix since 2023, November). Grand Canyon National Park (Arizona, 4h drive from Vegas) — absolute must, 446 km long, 29 km wide, 1,829 m deep, one of the world's most impressive natural landscapes, 6 million visitors/year. Colorado Plateau and Utah parks: Zion (vermilion canyon, vertiginous Angels Landing hike), Bryce Canyon (red hoodoos, unique rock formations), Arches (2,000 natural arches including Delicate Arch), Canyonlands (canyons and mesas), Capitol Reef (160 km geological fault), Monument Valley (iconic mesas, Navajo land, John Ford and his Westerns), Antelope Canyon (photographic slot canyon, Navajo land Page). Yellowstone National Park (Wyoming-Montana-Idaho, 9,000 km²) — world's first national park (1872), UNESCO site, active supervolcano, 50% of world's geysers (Old Faithful), Grand Prismatic Spring (unreal colours), bison and grizzlies, Grand Canyon of the Yellowstone. Grand Teton (Wyoming, adjacent Yellowstone, Tetons range). Glacier National Park (Montana, Canadian border, Going-to-the-Sun Road).
The pitch is clear: this is the par excellence mythical road trip US region. Plan 14-21 days for the classic loop Las Vegas → Grand Canyon → Page → Monument Valley → Arches → Bryce → Zion → Las Vegas. Essential car rental, SUV recommended, significant distances (Las Vegas-Grand Canyon 4h, Grand Canyon-Monument Valley 3h, Bryce-Zion 1h30). Favour May-June or September-October to avoid summer heat. Book Grand Canyon, Yosemite, Yellowstone lodges 6 months ahead.

Our verdict
Western Parks form one of the world's most beautiful road trips — the classic 14-day loop: Las Vegas (2 nights) → Grand Canyon South Rim (2 nights) → Page Antelope Canyon + Horseshoe Bend (1 night) → Monument Valley (1 night) → Arches Moab (2 nights, add Canyonlands) → Bryce Canyon (1 night) → Zion (2 nights) → Las Vegas. Favour May-June or September-October to avoid summer heat (Vegas 40-45°C, Grand Canyon Bottom 45°C) and enjoy reduced crowds. Fly Paris-Las Vegas via LA or NYC (mandatory stopover, 14-16h total, €800-1,400 return). Rent an SUV ($60-100/day) at Sixt or Enterprise at LAS. Book intra-park lodges (El Tovar Grand Canyon, Bryce Canyon Lodge, Zion Lodge) 6 months ahead — otherwise stay at gateway town motels (Tusayan for Grand Canyon, Springdale for Zion, Page for Antelope, Moab for Arches). For Yellowstone, add a separate trip (3,500 km from Las Vegas — prefer direct flight to Bozeman Montana or Jackson Hole Wyoming). America the Beautiful Pass ($80/year, all parks) instead of paying $35/vehicle each entry.
