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.

Javni prijevoz u Riverheadu uglavnom pruža Suffolk County Transit, koji upravlja autobusnim linijama koje povezuju ključna područja, uključujući liniju 92 koja povezuje Riverhead s Westhamptonom. Autobusi obično voze prema fiksnim voznim redovima, primjerice svakih 60 minuta, što može zahtijevati planiranje za pravovremeno putovanje. Infrastruktura ovog područja podržava ove usluge, ali zbog raširenosti odredišta možda će biti potrebno pješačiti između stanica i konačnih odredišta. Javni prijevoz može biti praktična opcija za kretanje po gradu, iako njegova pogodnost može ovisiti o konkretnoj liniji i vremenskim potrebama putnika.
