Crystal Lake offers a mix of walkable areas, particularly in its historic downtown and surrounding neighborhoods, where sidewalks and tree-lined streets create a pedestrian-friendly environment. Many amenities, such as shops, restaurants, and recreational spots, are within walking distance in these areas. However, walking may be less practical for accessing locations farther from the city center due to greater distances and limited pedestrian infrastructure in some parts. Seasonal weather, including cold winters and hot summers, can also impact the comfort of walking as a primary mode of transportation.

Andar en bicicleta es otra forma práctica de moverte por Crystal Lake, ya que la zona ofrece carriles bici y senderos que conectan varias partes de la ciudad. Algunos senderos, como los del bosque de Sterne, tienen un terreno montañoso, lo que puede resultar atractivo para los pasajeros que se sienten cómodos con los cambios de altura. La ciudad cuenta con infraestructuras aptas para bicicletas, como rutas y calles designadas para ello. Sin embargo, la topografía y las distancias entre destinos pueden requerir planificación, especialmente para los pasajeros menos experimentados. Ten en cuenta siempre las condiciones de la carretera y evita las calles con mucho tráfico cuando sea posible para que el viaje sea más seguro.

Public transit options in Crystal Lake include the Metra commuter rail and Pace suburban bus routes. The Metra station in Crystal Lake connects to Chicago and other nearby areas, making it a convenient choice for regional travel. Pace buses provide local service, including routes linking Crystal Lake to neighboring towns. While public transit can be a practical option for certain commutes, the spread-out nature of the area may make it less convenient for reaching some destinations. Weather conditions, particularly during winter, could also impact travel times and comfort for those relying on public transit.
