To access the beach, you can drive through the end of Kaka Street, where you'll encounter a stretch of soft sand before reaching 90 Miles Beach. The speed limit is 30km, so it's advisable to have a 4WD or AWD vehicle. Additionally, it's important to be mindful of the tides and not venture too far down the beach, as there are limited entry and exit points. Overall, the experience and views are truly breathtaking.
