What a great place to be based for a week !

Leverick Bay can set you up with car rental, and I do believe LB Water Sport can rent you a dinghy for water exploration, too. There is " ferry service" in and around North Sound so you'll be able to get around even if you don't choose to rent a dinghy.

The Crawl is a snorkler's paradise just toward Spanishtown from the Baths. It is a good swim from shore, worse in surf/swell/wind, so take that into consideration before you get your heart set on it.

You can check out the snorkeling from Prickly Pear.

Ask whether the glass bottom boat tours are still available, as well as the possibility of a tour of Necker Island.

In the past it has been allowed to dinghy over to Mosquito Island and snorkel the small reef off Honeymoon Beach. Check with the folks at Leverick before you attempt that one.

Ditto, check with Leverick-- about whether you can dinghy into the landing at Biras Creek and walk out to Deep Bay. The beach there is very nice, sheltered, although I've never heard the snorkeling is excellent, it might be a " glad we went and saw a bit of heaven."

Savannah Bay and Spring Bay, definitely. The food at Leverick is completely awesome, and " sand gravity" may convince you to stay close by, but Coco Maya, Top of the Baths, Hog Heaven are three " don't miss" eating adventures. Taxi service is available if you don't choose to rent a vehicle.

Take the " ferry" over to Saba and/or Bitter End. Ask about a dinghy rental for getting out into Eustacia Reef -- I'm guessing this could be your gal's Turtle prize. There is dinghy mooring, there may also be morning/afternoon trips scheduled from Bitter End.

Great dive shop at Leverick-- Dive BVI. By all means , check with them for excursions, I do believe they have an Anegada day trip in their offerings. That is a do-not-miss. Fair warning, Anegada can be downright addicting, even as a day trip. You won't be the first one caught in that spell, but you may also escape that affliction.

Sheesh, I'll shut up before I have you staying 2 weeks.

OOPS. Just saw in another thread that you ARE staying another week on boat charter.... LOLOL pretty sure you've got all the bases covered !
