Ontario, California, offers some walkable areas, particularly in its downtown and urban zones, where sidewalks and pedestrian pathways are present. However, walking as a primary mode of transportation may be less practical in other parts of the city due to the spread-out nature of the region and limited pedestrian infrastructure in certain areas. The weather, often warm and dry, can be pleasant for walking, but longer distances between destinations may make it less convenient. Walking is best suited for short trips or exploring specific neighborhoods rather than as a comprehensive way to navigate the city.

Cycling in Ontario can be a practical way to get around, depending on your destination and comfort with road cycling. The city features bike-friendly trails like the Pacific Electric Inland Empire Trail and Cucamonga Creek Trail, which provide scenic and safe routes for cyclists. However, urban areas may have limited dedicated bike lanes, requiring riders to share the road with vehicles. The relatively flat terrain makes biking manageable, but distances between key destinations could be a factor to consider. Always follow local traffic laws and plan routes carefully for a smoother experience.

Public transit options in Ontario include several services for getting around the city and nearby areas. Omnitrans provides bus services across the San Bernardino Valley, including routes that connect key locations within Ontario. Metrolink trains are available for regional travel, linking Ontario to other Southern California cities. The infrastructure supports these transit methods with designated stops and connections, but the spread-out nature of the area may make some destinations less accessible without additional travel modes. Public transit can be a practical choice for those traveling to well-served areas, though planning routes in advance is recommended.
