ok i remember it being on in the 70s'
It concerns a group of people stranded on an island much like Lost but it may have been an island in the Bermuda Triangle, i'm not sure.
At the end of each episode they went into a different area through a portal, and the difference could have been in either time or location on the earth.
There were about 6-7 people in the group and the entire series only lasted 6-7 episodes. i believe it was cancelled
can anyone help?
thanks in advance
Edit: Found it, and it was called "The Fantastic Journey"

from IMDB
"A scientific expedition in the Atlantic Ocean becomes lost in the Bermuda Triangle and washes up on an uncharted island. They meet up with travellers from other times, planets and dimensions who have also become trapped, and together they "slide" through portals from one dimension to the next hoping to find the one that leads home"
