The landscapes transition from the agricultural San Joaquin Valley (vineyards, almond orchards) near Fresno to the dry, creosote-studded Mojave Desert around Barstow. The iconic Calico Ghost Town near Barstow offers a glimpse into silver-mining history. Further east, the Kelso Dunes in the Mojave National Preserve (detour via Kelbaker Road) are a must-see for sandboarding. The Afton Canyon, nicknamed the 'Grand Canyon of the Mojave,' features dramatic cliffs and the Mojave River as it emerges from the sand.

• UNESCO Heritage: None directly on route, but nearby sites include Yosemite National Park (detour) and the Grand Canyon (further east).
• Natural bridge: The Kolob Canyons section of Zion National Park, accessible from I-15 exit 40, showcases towering red rock formations just off the highway.
• Local commerce: At Baker, visit the world's tallest thermometer (134 ft) and the Bun Boy diner for classic California road food.

In southern Utah, the Virgin River cuts through the red sandstone, creating the dramatic scenery near St. George. The St. George Dinosaur Discovery Site at Johnson Farm features fossilized footprints. For local crafts, browse the shops in St. George's historic district. The town of Kanarraville itself is tiny, but nearby Kanarra Creek Falls (a slot canyon hike) is a hidden gem that requires a permit from the town hall—only 150 permits are issued daily.

Safety considerations: In summer, desert temperatures exceed 110°F (43°C) between Barstow and St. George. Carry extra water (1 gallon per person per day) and have your vehicle cooling system checked. In winter, snow is possible from St. George northward; chains may be required on I-15 near Cedar City. Road quality is excellent, but watch for flash flooding in slot canyon areas during monsoons (July–September).

• Family stops: Peggy Sue’s 50s Diner in Yermo (dinosaur-themed), the Atomic Museum in Las Vegas, and the St. George Children’s Museum.
• Pet-friendly: Most rest stops have designated pet areas; many Motel 6 locations along I-15 accept pets. The Virgin River trail in St. George is dog-friendly.
• Fatigue management: Take breaks every 2 hours. Ideal rest zones include the Tejon Pass rest area (scenic views), the Barstow Station (McDonald’s in a retro train), and the Mesquite Visitor Center (clean facilities).

Hidden off-route spot: The ghost town of Rhyolite, Nevada, near Beatty, is a 45-minute detour off I-15 (via Hwy 374) and features crumbling buildings and an outdoor art installation. It's less crowded than Calico. Another gem: the Tule Springs Fossil Beds National Monument north of Las Vegas, where you can see Ice Age mammal fossils.
