Distance from London gatwick south terminal to London stansted?

It is not easy to transfer between two terminals,but good news is that there is shuttle train service between south and norh terminals which run 24 hours a days.

it takes 2 minutes between 2 terminals

the main train line runs to south terminal of the gatwick airport

so if you wanna go to north termiinal ,follow north terminal signs and take the stuttle train service and vice vera

this service is free

hope it clear now
