Okiwi Bay is a small settlement and sheltered bay on the western edge of the Marlborough Sounds, located on Croisilles Harbour. It lies approximately 92 km from Blenheim, a drive of about 1 hour 20 minutes via Rai Valley, and around 68 km from Nelson, roughly 1 hour 6 minutes.

About Okiwi Bay
Okiwi Bay sits at the head of a long sheltered inlet off Croisilles Harbour. The surrounding hills and limited fetch keep the water inside the bay calm for most of the time, making it suitable for swimming, kayaking and small-boat use.
The western shore consists mainly of stones and shingle, while a sandy patch appears at the eastern end between rocks at low tide, providing the preferred family swimming spot amid native bush.
The Okiwi Bay Holiday Park is the main settlement feature and primary reason most visitors come. It offers powered and unpowered sites, a lodge and cabins, plus a convenience store, hot showers, kitchen and laundry.
The park is privately owned and operated; it is not a Department of Conservation campsite. The former DOC Okiwi Bay Campsite is closed for overnight stays and may only be used for picnics and parking.
The bay functions as a key fishing and diving base. The public boat ramp sees regular use in summer, with launches heading to the outer Marlborough Sounds, French Pass and surrounding areas. The sealed road from Rai Valley narrows and winds closer to the bay but remains fully accessible by standard vehicles.
The Drive to Okiwi Bay
The route from Blenheim follows State Highway 6 through Rai Valley before turning onto Okiwi Bay Road. The entire road is sealed. Allow extra time for the winding final section. No 91 or 95 petrol is available beyond Rai Valley, though diesel can be obtained at the holiday park.
Activities at Okiwi Bay
Visitors enjoy swimming in the sheltered waters, fishing from the shore or by boat, scuba diving, kayaking and short walks in the surrounding native bush. The location also provides a convenient starting point for boat trips toward French Pass and the outer Sounds without requiring long gravel-road travel.
