I have very little knowledge of the waters of the lower keys - as you can see from the charts Key Largo
is about 100 miles north of Key West. Once you get to the upper keys the places to access the ocean from bayside get farther apart so that is why I was asking which side. For me to take my boat to the ocean from Blackwater Sound - it is about one half to one day because I either have to go south to Snake Creek or north to Angelfish Creek. You can definitely bring a boat with a five foot draft up this far on the bayside just stay in the channels or like CaptForce said travel in Hawks Channel just offshore
on the ocean side. We have some great diving
, snorkeling, and fishing grounds up here.
Have a fun trip and hope you catch lots of lobster and fish!
