Yes, you have to take a left under the bridge and then then the secret unicorn picks you up and takes you to the gates, retrieve the key from the unicorn's mouth and use it to open the lock, Lord gēœsæçh will help you navigate the treacherous waters of sósqèrlçēœ, and then you will be well on your way to completing your mission as long as you keep reciting the secret chant-prayer provided to you on the scroll that exited the unicorn's anus upon your arrival.
wasnt there a left turn at albequque somewhere in between the unicorn mouth and anus???.....oh no wait that was to alladins cave....sorry never mind....
