Bull Run

The bull shark season

Bull sharks arrive at Bimini's shallow waters primarily between December and March, following patterns related to water temperature and prey availability. During peak season, multiple individuals may be present on a single dive, their stocky silhouettes unmistakable against the sandy bottom.

The sharks' presence in such shallow water creates unique viewing conditions. Unlike deeper sites where encounters may be brief, Bull Run's 20 to 40 foot depths allow extended observation as the sharks patrol their territory.

Dive operations and safety

Bull Run operates as a baited dive, with experienced operators controlling food release to manage shark behavior and diver safety. Some operators offer cage diving experiences for those seeking additional security, while others conduct open-water encounters for experienced divers.

Winter water temperatures of 75 to 77 degrees Fahrenheit suggest a full wetsuit. The shallow depth allows lengthy bottom times, with some extended encounters lasting 60 to 90 minutes. Operators typically limit group sizes to maintain safety protocols.

Year-round shark presence

While bull sharks are seasonal visitors, other species maintain year-round residence. Nurse sharks rest on the sandy bottom, lemon sharks patrol the reef edges, and blacktip sharks cruise through in small groups. This ensures shark encounters even outside bull shark season.

The site's proximity to North Bimini makes it easily accessible with minimal boat travel. Morning dives often offer the calmest conditions and most active shark behavior.

Getting there

Bull Run is accessed by dive boat from North Bimini, with boat rides typically under 15 minutes. Multiple operators offer shark diving experiences, including Bimini Big Game Club and Neal Watson's Bimini Scuba Center. Advance booking is strongly recommended during bull shark season as trips fill quickly.
