I second that!!! Tolo is fantastic. If you like night diving, visit Tolo during the day and then come back a few hours later, or just stay and repeat to see it’s magic after sunset. As with many sites in Bonaire, entries and exits can be challenging.
Webber’s Joy is a mini version of Tolo, at least in my opinion, which likewise does not disappoint. This one has a much shorter sand flat; however, it does sport a dense gorgonian forest, so be on the look out for Caribbean squid in the water column and slender filefish within the gorgonias.
As time goes on, we’ve found our preference has significantly morphed from checking all divisites we could not visit during prior trips from not having enough time, to simply staying at our favorite sites and putting in 2, 3 and even 4 dives on the same day without driving all along the coastline.
STINAPA has done an amazing job with the stag horn coral at both of these sites. In just one year, the health and growth of them at both of these sites is impressive. Lots of life there. At Tolo, the stag horns are at the base of the dive site marker buoy-anchoring buoy (sometime hard to spot because of the way the site is configured and the designated parking areas), and at Tori, they are on the south side of the marker. Both are in the sand flats at around 20 feet or so.
BTW... I know you are asking about northern sites, but Tori is one worth visiting too. Just past the salt pier heading south, park immediately south of the second little bridge and use the salt works intake/outfall canal as your way in and out. Easy or easier access if you use the canal.
Enjoy your trip.
