Route 66: The Mother Road

Often referred to as the "Mother Road," Route 66 is arguably the most iconic highway in America. Stretching 2,448 miles from Chicago to Santa Monica, California, it cuts through the heart of the U.S., traversing diverse landscapes and connecting small towns with rich histories. Route 66 has become synonymous with American freedom, exploration, and nostalgia, and it remains a popular route for overlanders seeking to experience the spirit of the American road.

Route 66 in the Southwest

In the Southwestern U.S., Route 66 spans across Arizona, New Mexico, and into parts of California. This stretch of the road is known for its desert vistas, dramatic red rock formations, and significant historical landmarks. From the Grand Canyon to the Petrified Forest, and from Seligman to Oatman, the Route 66 experience in the Southwest is nothing short of extraordinary.

Start/End: Chicago, Illinois to Santa Monica, California (Southwest section runs from Arizona to California)

Length of Southwest Section: Approximately 1,100 miles

Terrain: Paved highways, some gravel and dirt paths, occasional washouts, and minor off-road sections.

Highlights:

• Seligman, Arizona: Known as the birthplace of Route 66 revival. This small town offers vintage diners, motels, and shops that take you back in time.
• Grand Canyon: A short detour from Route 66, this world-famous natural wonder is a must-see.
• Petrified Forest National Park: Famous for its fossilized trees and unique desert landscape.
• Oatman, Arizona: A ghost town with wild burros that roam the streets.
• Santa Monica Pier: The symbolic end of Route 66.

Overlanding Route 66

While Route 66 is mostly paved, there are some unpaved stretches that require an off-road vehicle or 4WD for easy navigation. Seligman to Oatman is one such stretch, with a few dirt roads and hills that require a capable vehicle. The Mojave Desert sections, though paved, can get quite hot in the summer, so proper preparation is key.

4WD Considerations: Some off-road diversions, like the Oatman-Needles Highway, feature a dirt road route that can be tough but manageable for a capable overlander.

Recommended Vehicle: For most of the Route 66 journey, a well-equipped SUV or crossover is sufficient. However, a more rugged 4WD vehicle is recommended if you plan on tackling off-road segments or exploring the desert regions.

The Mojave Road: A Trail through the Desert

The Mojave Road is a historic 140-mile trail that traverses the Mojave Desert from the east to west, cutting through California from the Colorado River to the San Bernardino Mountains. Known for its rugged terrain and natural beauty, this trail offers a true overlanding experience. The Mojave Road was once an important Native American trading route and later became a path for settlers and military expeditions.

Mojave Road Route Overview

Length: 140 miles (one way)

Start/End: Colorado River (east) to San Bernardino Mountains (west)

Terrain: A mix of dirt roads, desert washes, rocky trails, and some sand dunes. Several river crossings can add to the challenge during the rainy season.

Highlights:

• Mojave National Preserve: The Mojave Road runs through the preserve, showcasing vast desert landscapes, sand dunes, and the unique Kelso Dunes.
• Cima Dome: A massive, isolated dome formed by volcanic rock, providing expansive views of the desert.
• Mojave Desert’s Rock Formations: These formations include the Teutonia Peak and the Bristlecone Pine Forest, known for some of the oldest trees on Earth.
• Mormon Point: A historic site where Mormon settlers traveled, marking an important part of the desert crossing.
• Historic Watering Holes: You’ll pass by several springs that were once vital water sources for travelers on the Mojave Road, including the Pinto Wells.

Overlanding the Mojave Road

Overlanding the Mojave Road is a challenging but rewarding experience. This trail is primarily dirt and gravel roads, with some rocky sections that require higher ground clearance. The route is typically dry and barren, so you’ll need to carry ample supplies, including water, fuel, and recovery gear. Some segments may require water crossings during certain seasons.

4WD Considerations: The Mojave Road is a trail best suited for high-clearance 4WD vehicles, and having off-road tires is essential. Sand dunes, loose gravel, and rock sections will require skilled driving and vehicle handling.

Recommended Vehicle: A mid- to full-sized SUV or truck with solid off-road capabilities, such as a Toyota 4Runner or Jeep Wrangler, would be ideal for the Mojave Road.

The Old Spanish Trail

The Old Spanish Trail is another historic overland route that played a significant role in the American Southwest. Spanning from Santa Fe, New Mexico to Los Angeles, California, this trail was originally used by Spanish explorers in the 16th century, and later became an important trade route.

Overlanding the Old Spanish Trail

The Old Spanish Trail is a diverse route, with some sections involving technical off-road driving while others follow paved roads. It's essential to check the route for road conditions before embarking, as some parts may require vehicle modifications for tough terrain.

4WD Considerations: Off-road sections near Zion National Park and the Arizona desert can be demanding, so a capable 4WD vehicle is essential for these stretches.

Recommended Vehicle: A full-sized 4WD vehicle with strong off-road capabilities, such as a Toyota Land Cruiser or Jeep Gladiator, will offer the comfort and strength needed for longer journeys and varied terrain.

The Arizona Trail

For those looking for a shorter, but still epic overlanding adventure, the Arizona Trail offers a 800-mile route across the Arizona desert and through the Grand Canyon. This trail takes you through diverse landscapes, including deserts, mountains, forests, and canyons.
