Tantabiddi Boat Ramp sits at the mouth of Tantabiddi Creek, approximately 38 kilometres from Exmouth in Western Australia, and serves as the primary gateway to the World Heritage-listed Ningaloo Reef.

Managed by the Shire of Exmouth, the two-lane concrete facility with finger jetties is the departure point for major commercial tours including whale shark and humpback whale swims, glass-bottom boat trips, diving and snorkelling charters, and sport-fishing expeditions targeting marlin, sailfish, and Spanish mackerel.

Dolphins and dugongs are regularly spotted in the surrounding waters. Because Tantabiddi Creek is ephemeral, heavy rainfall and cyclonic flooding can deposit sand and sediment at the ramp entrance, periodically restricting launching.

During peak season the facility operates at capacity, creating competition between recreational boaters and commercial operators.

A redevelopment project has been underway to address these constraints and improve access to one of the region's most heavily used boating facilities.
