Backdoor (Cactus) is located in the northern corner of the bay and offers a right-hand reef break that can deliver some intense rides. While it can be a bit hectic, it’s a spot that attracts those looking for good performance. The crowd isn’t usually too thick due to its tricky peak, which can often put off locals, making it a decent choice for travelers who want to enjoy some thrilling surfing without too much competition.

The waves here work best with swells coming from the southwest, with south and west swell angles also delivering something rideable. When the swell hits about 3 ft (1 meter), you’ll really start to see the potential of the barrels, especially on a low tide when the reef gets exposed. This break is purely for experts, requiring skill and confidence to navigate the sharp, uneven reef while chasing down those right-hand barrels. For the best conditions, look for northeast winds.

It's worth noting that Backdoor (Cactus) can handle a range of swell sizes, but timing your session with the right tide is essential to fully enjoy what this spot has to offer. When the conditions align, it can deliver some solid tube rides that will keep advanced surfers coming back.
