Hillsborough Bay is a saltwater bay forming the northeastern lobe of Tampa Bay on Florida's central Gulf Coast. It is a broad, open bay with a primarily urbanized shoreline, characterized by fixed docks, seawalls, and some floating docks along its edges. The bay is the terminus for the 54-mile Hillsborough River, which flows into its upper reaches. The entire Tampa Bay system, including Hillsborough Bay, experiences a tidal variance of approximately 1 to 2 feet. This tidal movement influences currents, and paddlers should account for this variance when launching from fixed structures. The bay's open nature means it can be exposed to wind and wave action, particularly during inclement weather. Cypress Point Park is located on the bay's western end offering beach access. Other potential access points include parks and marinas along the shoreline, such as those for the adjacent Upper Tampa Bay area, like Coopers Bayou or Philippe Park, which involve a fee for ramp use. The water is saltwater, and the environment is mostly urban, though paddlers can explore mangrove islands in the adjacent Upper Tampa Bay. Wildlife viewing opportunities are present, particularly where the freshwater Hillsborough River meets the bay. Due to the urban setting, paddlers should be prepared for boat traffic, especially near channels and marinas. The best times for paddling are typically during the cooler months from late fall to early spring, offering milder weather and fewer insects.
