Infrastructure Safety & Road Quality

I-15 is typically in good condition, but watch for construction near Nephi (2024-2025 resurfacing project). Winter driving can be hazardous from November to April; carry chains. Cell service is spotty between Beaver and Fillmore (milepost 180-200). Emergency services are reliable, with hospitals in Cedar City (Valley View Medical Center) and Salt Lake City (University of Utah Health).

• Road Condition: Excellent in dry months; occasional potholes after winter.
• Rest Stops: Milepost 150 (near Fillmore) and milepost 280 (near Ogden) have clean facilities.
• Towing Services: Available along most of I-15; call *DOT for assistance.

Family and Child Suitability

This route is family-friendly with many interactive stops. The Children's Museum of Utah in Salt Lake City and the Tracy Aviary are great breaks. At Lava Hot Springs, the Olympic-size swimming pool and water slide park (open summer) entertain kids. Pack games for the car, as some stretches have no attractions.

Pet-Friendly Framework

Most stops allow leashed pets, but not all national parks. Snow Canyon and Bear River Refuge require leashes. Lava Hot Springs' hot pools do not allow dogs, but there are nearby pet-friendly hiking trails (e.g., Scout Mountain). Many hotels along the route, like La Quinta in Brigham City, accept pets.

Hidden Off-Route Spots

Just off I-15, explore the ghost town of Sunshine (exit 190, 30 miles west) for abandoned silver mines. Another hidden gem: the Grotto in Keystone Canyon (exit 350) features a natural waterfall and swimming hole.
