Walking in Groton can be a practical option in certain areas, particularly in more centralized parts of town where destinations are closer together. However, the town’s infrastructure is largely car-oriented, which can make walking less convenient in some neighborhoods. Sidewalks and pedestrian pathways are present in select areas, but their availability may vary, and distances between key locations can sometimes be significant. Weather conditions, especially during colder months, may also influence the comfort of walking. While walking is feasible for short trips or within specific districts, it may not always be the most efficient way to navigate the broader area.

Biking in Groton is a viable option for getting around, especially for shorter distances. The area includes some bike-friendly infrastructure, such as designated bike lanes and paths, which can make navigating certain parts of the town more accessible. However, the availability and connectivity of these routes may vary, and some areas might require sharing the road with vehicles. The town’s layout and distances between destinations could influence the convenience of biking as a primary mode of transportation.
