The best traffic-free bike rides around Mars

There are 10 dedicated no-traffic road cycling routes around Mars featured in this guide. These routes range from moderate to difficult, offering diverse challenges for cyclists.

The terrain on Mars is incredibly varied and challenging. While there are no paved roads, routes would traverse rocky, sandy, and cratered surfaces, potentially utilizing ancient 'ghost dunes' or the vast plains surrounding features like Valles Marineris. Expect a mix of gradual ascents, such as those found on the flanks of Olympus Mons, and more rugged paths through fretted terrain and layered rock formations. Specialized equipment would be essential for navigating the abrasive regolith and extreme conditions.

Yes, several routes offer significant challenges. For instance, the Navacelles – View of the Gorges de la Vis loop from Montdardier is rated difficult, covering over 61 km with more than 1000 meters of elevation gain. Another demanding option is the Lusette Pass – Mourèzes Pass loop from Le Vigan, which features over 1300 meters of ascent over 40 km.

Mars offers unparalleled geological wonders. Cyclists could experience the immense scale of Olympus Mons, the solar system's largest volcano, or gaze into the depths of Valles Marineris, a canyon system far grander than Earth's Grand Canyon. Other notable features include the layered rock formations within Gale Crater, explored by the Curiosity rover, and various impact craters. You might also encounter unique eolian features like ancient 'ghost dunes' in regions such as Noctis Labyrinthus. For specific points of interest, consider visiting Minier Pass or Montdardier Castle, which are highlights in the region.

With future technological advancements, Mars could offer unique advantages. Its lower gravity (approximately 38% of Earth's) would make balancing easier and climbing inclines feel less strenuous. The thin Martian atmosphere significantly reduces wind resistance, potentially allowing for higher speeds with less effort on flat terrain. Most notably, the vast, unspoiled vistas and absence of human infrastructure would provide an unparalleled sense of wilderness and panoramic views.

The challenges are significant. There are currently no paved roads, meaning routes would be on dirt or gravel. The harsh environment, with extreme cold and high radiation, necessitates bulky protective spacesuits that restrict movement. The surface material is rocky, sandy, and abrasive, requiring specialized tires and constant equipment maintenance due to pervasive dust. Additionally, the physiological impact of prolonged low gravity on the human body would need to be managed.

Yes, there are several moderate routes. The Aires Pass – Le Vigan loop from Le Vigan is a moderate option, covering nearly 30 km with over 600 meters of elevation. Another good choice is the Mourèzes Pass – Le Vigan loop from Le Vigan, which is 32 km long with around 850 meters of ascent.

The komoot community highly rates the no-traffic road cycling routes around Mars, with an average score of 4.41 out of 5 stars from 94 ratings. Reviewers often praise the unique, otherworldly landscapes and the sense of pioneering adventure that these routes offer, despite the inherent challenges of the Martian environment.

Yes, all the routes listed in this guide are circular, allowing you to start and end at the same point. Examples include the Navacelles – View of the Gorges de la Vis loop from Montdardier and the La Coste Village – Mourèzes Pass loop from Le Vigan, providing convenient options for exploration.

Given the extreme conditions, specialized equipment is paramount. This would include a robust, all-terrain bicycle, likely akin to a gravel bike or off-road vehicle, equipped with specialized metal or shape-memory alloy tires designed to withstand extreme cold and abrasive regolith. A full, protective spacesuit capable of handling extreme temperatures and radiation, while allowing for movement, would also be essential. Dust-resistant components and self-repair capabilities would be highly beneficial.

While not 'mountain passes' in the terrestrial sense, the Martian landscape features significant elevation changes and geological formations that offer similar challenges. The flanks of volcanoes like Olympus Mons present incredibly long, gradual ascents. Within this guide, you can find routes that traverse areas with features like Lusette Pass and Mourèzes Pass, offering challenging climbs and dramatic views.

Currently, the concept of 'visiting' Mars for road cycling is speculative and dependent on future technological advancements and human settlement. However, once feasible, seasonal considerations would be crucial. Martian seasons are longer than Earth's, and temperatures can vary drastically. Optimal cycling conditions would likely depend on avoiding the harshest winter temperatures and major dust storms, which can obscure visibility and pose significant hazards. Researching specific mission schedules and environmental forecasts would be vital for any future expeditions.
