No ferry to Hassel Island. The kayaks at Frenchtown Marina might be an option with 1 adult and 1 child in a kayak.

They are not too young for the tour but you'll end up in 2 - 2 seater kayaks with 1 adult and 1 child in ea. kayak. Haven't done the HI tour (have doen the lagoon trips) but heard it's fun.
You can also contact the Historic Preservation Society to see if they will be having any functions/trip during that period and Ronnie Lockhart may be able to give you info on someone to take you there and back if not. You can also check with the Water Island Ferry operator as I think someone will take people over, just can't remember who it is.

Forget the Water Island ferry operator as I asked him this morning and he said they don't and didn't know who does.

Thanks for the info. From what I understand, the historical society could do it, but they don't have children's vests on their boat (mandatory). My wife had called VIEcotours and was told they were too young.

I'm just hoping we got a little misinformation...

Give the St Thomas Historical Trust a call. Here's a link to their website and the telephone number to call for Hassel Island tours:

Note the caveat about the physical nature of the tour!

As mentioned, haven't done the Hassel Island tour w/Ecotours but they did take young kids on the Mangrove Tour (or used to). Had lots of family visiting last yr. (one who had been the last born on Hassel Is.) and they found someone to take them over. I'll contact them to see if they remember who it was and contact number. It was someone with a boat in Frenchtown.

Cool, thanks Alana33.

Sorry, my cousin couldn't remember who it was that took them all over to Hassel Is.
Maybe someone at Hook, line and Sinker or the Marina next door would know.
Good Luck.
