The Big Wall - Zanzibar & Pemba

Witches Kitchen is one of those Curaçao sites we always look forward to, particularly when the current is pushing just right. It's a proper drift, so you really do just hang out and let the ocean do the work. The reef here, topping out around 20 metres, feels very active, especially with the surge working the corals. We love dropping in and immediately feeling that gentle pull, knowing we're in for a ride. Keep an eye out for the smaller stuff tucked into the gorgonians and sponges – our favourite is hunting for the tiny Spinyhead Blennies bobbing their heads. You’ll often see schools of Bigeye Mojarra shimmering against the blue, and the occasional Trumpetfish hanging vertically, pretending to be part of the reef. We've had some great encounters with curious Grey Snappers here, too, and if you’re lucky, an Eagle Ray might glide by in the distance. The lettuce corals spread across the bottom are particularly vibrant, catching the light as you drift over them. This spot is perfect for divers who enjoy a relaxed pace and appreciate a good drift, especially with a local guide who knows the currents like the back of their hand.
