Can i travel to Cyprus (Larnaca) from Turkey via Ercan?

As the title says, me and my partner would like to travel to Cyprus, but we have to be in Turkey for a meeting first. I know there are flights to Ercan, but i was wondering after landing Ercan and maybe spending a few days in the northern part, if i could jump on a taxi and go to Larnaca where we would like to stay a couple of weeks. Would that be a problem with our UK passports?
