Willemstoren Lighthouse - Klein Bonaire
Willemstoren Lighthouse, around the southern tip of Klein Bonaire, offers a very different vibe to the usual mooring line dives. We usually drop in from a boat, drift north with the current, and just see what comes our way. The reef here, a gentle slope, is where we often spot Apricot Bass and Bicolor Basslets darting around. It’s also one of the few spots we regularly encounter the Hakeling and the subtle Spinythroat Scorpionfish. If you're into spotting the smaller stuff, those Puffcheek Blennies and Nine-lined gobies are usually out. We find it's a calm drift, great for a relaxed afternoon.
