Nope. It was supposed to be off the coast of Hawaii. The pilot episode was filmed on Hawaii, but the "island" was on the backlot. The lagoon was a big pond and would sometimes get really nasty. Cast members from time to time refused to go in it.

From www.gilligansisle.com:
"The Skipper, Jonas Grumby, and his first mate, Gilligan, had been running an excursion boat, the S.S. Minnow, from Honolulu, Hawaii, offering a three- hour tour that included a free lunch aboard the boat."
