This may be a disappointing answer, but you can't actually see the sea from the Eurostar. When you go through the tunnel and look out of the window, all you can see is your reflection in the glass because it's quite dark outside.
Is Eurotunnel pressurised?
The Channel Tunnel is open at both ends, so the air pressure inside the tunnel is pretty much the same as the air pressure at sea level (just a little more, since the channel tunnel is at a lower altitude than sea level).
How was the Eurotunnel built underwater?
Engineers used two systems of tunnel linings – cast iron segments bolted together and precast concrete rings. The TBMs excavated a huge amount of chalk. On the French side, the chalk was crushed, mixed with water, and pumped inland behind a specially built dam 37m high.

How did they get the water out of the Eurotunnel?
Water is drained from the tunnels by large submersible pumps, and reliable operation is critical - there are more than 200 train movements in each direction every day. Eurotunnel engineers sought a high-quality solution to control all pumping processes during excavation.
What would happen if Eurotunnel flooded?
First, the tunnel's automatic safety systems would detect the water and trigger an alarm to alert the train driver and the control center. The train would be brought to a stop, and the passengers would be instructed to stay in their cars.

Could the Euro tunnel collapse?
Collapse of the tunnel isn't what would make it impassible first. The tunnel itself might well last a century or so, but if there's no electric power for as little as a few weeks the tunnel will be closed by water seepage that can't be pumped out.
Does the Chunnel leak water?
