I've always heard the dive there was the end of the
Corporal Meiss dive site - one that's hard to find on most site listings. There used to be a couple huge purple sponges pretty much straight out in about 60' but I'm not sure they're there now since one of the hurricanes some years ago. It's a good dive, we did it twice when we didn't feel like going anywhere else. It wouldn't make my top 20 list though.
You do get a pass to use Buddy's drive-thru if staying at Belmar. I almost think Belmar is even easier though - the parking lot is 20-100' from the dive shop and you can even park temporarily by the gate for tanks - it's streetside and 20' from the main road south. The whole dive shop area is at the south end of the property near to the office - nothing is much of a walk.
If you have a
ground floor unit at Belmar - there's a locking dive closet outside your back door. Tile floor and pole for hanging suits. The truck is parked maybe 40' away. Your patio door opens on a west facing area, 20' away is the pool then just past that steps down to the dive dock. It's a very compressed property.
The upstairs units have semi-secure lockers by the dive shop but you may want to bring a lock. I haven't been there since Buddy took over but prior to that your condo key got you into the public areas of the shop 24/7 for tanks, Nitrox Analyzer and suit hangers/rinse tank. There's also another tank on the dive dock. And I read they stage tanks there now also for guests.
I liked it because no one ever used the pool at night and it wasn't the worst house reef we'd dove. Buddy's etc. and the other north sites will be fishier most likely. Bachelors Beach is walking distance also but drive over with gear.
As mentioned there's no food there. We ate breakfast once at Hotel Roomer a few blocks away but it was average.
So everything food is a drive - at least to the Plaza Resort or south end of town. There's a Courtyard by Marriott being built now on the east side of the lagoons by the airport so they might have an option for meals by the time you go. Everything else till you get to the Plaza is condos or houses - but you might as well drive another 1/2 mile around the turn into south Kralendijk from there. We're talking under 10 mins. total drive time - just around the lagoons and past the airport. Belmar is in North Belnem so not much of a drive to town. Fairly close to Van Der Tweel or Warehouse Foods also from the south.
