Curious by the title? I bet!
Ok here are a few ways I see to get access to the northern locked-away continent and the precious religions it holds.
Once you have a single city up there, you have an airport there ... lifting in the big guns ... you get the idea...
1.) Getting promotions is not a problem in this game so promote your units up to Guerilla III (gunpowder and melee only). Guerilla III has the nice side effect that units can enter mountain tiles ... next to useless on normal games. So just invade Spain or France with them.
((Do I have to add a winking smiley here??)) Just to be save -
2.) In the late game: Explode a nuke or use a spy to deliberately melt down a nuclear plant to trigger global warming. Now wait with your large invasion fleets next to the icebergs blocking the northern continent until the right iceberg tile melts due to global warming. And there you go.

Plus: I think that melting icebergs is a nice concept.
3.1.) There are two spots near France where units can be unloaded although they cannot enter the land behind. In the early game, if the spot is not taken over by French culture yet, found a city their and try flipping a city on the other side. That will be next to impossible I think, because i) by the time Rome can found cities across the oceans, France will be quite developed culture wise.
ii) flipping a city will need amazing culture. But where to get it?
3.2) Just unload a settling party on these spots, but do not found city there. If the spots are already taken over by French culture you must have an open borders agreement of course to enter the beach. Now close that border and see where the settling party gets teleported. If the little one-tile islands inside the mountain keep sea are not all under cultural control, the computer might teleport your settler there rather than back to the Roman continent. (Depends on the distance I think)
There is another option here. Have open borders also with Spain. Close borders with France, hope the units get transported into Spain, move the units up to the northern coast of Spain and then close borders with Spain. The distance to the northern one-tile islands should be rather short now.
(I actually tried this method, but it crossed my mind to late into the game. By then I could not get an open border agreement with Spain, despite gifting lots of tech.) Also I find this way to be a bit dodgy and exploitive, but it would have been a nice coup.
4.) Nuke the hell out of them and hope they offer a city for peace. Now I do not know if that actually works, since none of these cities would be under some Roman cultural pressure.
