Riverhead features a mix of walkable areas, particularly in its revitalized downtown, where pedestrian-friendly infrastructure supports easy access to shops, restaurants, and local attractions. However, outside the central area, distances between destinations can be more spread out, making walking less practical for some trips. Seasonal weather, including cold winters and hot summers, may also impact the comfort of walking. While sidewalks and crosswalks are present in many areas, the overall walkability depends on the specific location within Riverhead and the purpose of the trip.

Cycling in Riverhead can be a practical way to get around, though the area has limited dedicated bike lanes and cycling infrastructure. The town’s layout and distances between key destinations may make biking more suitable for shorter trips. Riders should be cautious on roads shared with vehicles, as bike-specific pathways are not widespread. The relatively flat terrain of Riverhead can make cycling manageable, but the lack of extensive bike-friendly infrastructure may require extra care when navigating.

I trasporti pubblici a Riverhead sono gestiti principalmente da Suffolk County Transit, che opera linee di autobus che collegano le principali aree, inclusa la linea 92 che unisce Riverhead a Westhampton. Gli autobus seguono generalmente orari fissi, ad esempio ogni 60 minuti, il che può richiedere una certa pianificazione per viaggiare puntuali. Le infrastrutture della zona supportano questi servizi, ma la distanza tra le varie destinazioni può rendere necessario camminare tra le fermate e la destinazione finale. I mezzi pubblici possono essere una soluzione pratica per spostarsi, anche se la loro comodità può dipendere dal percorso e dalle esigenze di orario del viaggiatore.
