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.

Sykling er en annen praktisk måte å komme seg rundt i Crystal Lake på, siden området byr på sykkelstier som forbinder ulike deler av byen. Noen stier, slik som de i Sterne's Woods, har kupert terreng, noe som kan appellere til passasjerer som er komfortable med høydeendringer. Byen har sykkelvennlig infrastruktur, inkludert angitte stier og gater egnet for sykkel. Topografien og avstandene mellom destinasjonene kan imidlertid kreve planlegging, spesielt for mindre erfarne passasjerer. Ta alltid hensyn til veiforholdene og unngå travle gater når det er mulig, for en tryggere tur.

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.
