When you get to the Turks and Caicos there are 2 places you have to go. (IMHO).

When arriving in the T&K from your direction and you want to cross the bank there's an anchorage between Big and Little Ambergris Cays. Just around the point to port is an anchorage and a great place to stop before going across the bank. There's a nice shifting sand bore you can swim to from the boat. Photo of Reylyn at that spot.

The second place we loved is Gracie Bay. You need to work your way in and it's a bit unnerving but it's easier than it looks. You just need to get used to coral heads on both sides and following the markers. Work your way in and anchor in Gracie By near Club Med. It's a good place to spend 3 or 4 days. We anchored inside the reef and took a taxi to a dive boat. Went diving for a day. It was great. If Denny is joining you there Gracie Bay is the place to go.

But then you know that. Have a good trip.
