Golden Bay / Mohua is a shallow, paraboloid-shaped coastal bay, an arm of the Tasman Sea protected in the north by the 26-kilometer-long Farewell Spit. This geography creates a large, open bay with significant fetch, making it susceptible to wind-driven conditions. The southern coastline, where paddling activity is concentrated, features towns like Takaka and Collingwood and borders the Abel Tasman National Park. Key access points for launching kayaks or SUPs include Ligar Bay, Awaroa Inlet within Abel Tasman National Park, and the tidal estuary near Totara Avenue. These launches provide direct access to the bay's waters and its interconnected estuaries and inlets, such as the Wainui Inlet, which can be walked across within two hours either side of low tide, indicating a substantial tidal range. Paddlers must plan around these tides, especially for estuary exploration and beach landings.

The bay's open nature means paddlers should be prepared for wind exposure and potential choppy conditions, particularly when crossing larger stretches of open water. Boat traffic can be expected, especially near popular areas like the Abel Tasman coastline, where water taxis and tour boats operate. The area is a known tourist destination with a relaxed vibe, offering paddlers views of golden sand beaches, turquoise waters, and bush-clad hills. Wildlife sightings may include New Zealand fur seals, and historically, the bay was a resting area for migrating whales. Paddlers should be aware of the marine reserve off the coast of Abel Tasman National Park and respect any local iwi protections, such as those for Te Waikoropupū Springs where touching the water is forbidden. Facilities are generally tied to coastal towns and holiday rentals, which sometimes offer kayak equipment for guest use.
