Ex 14:21-22
Then Moses stretched out his hand over the sea, and all that night the LORD drove the sea back with a strong east wind and turned it into dry land. The waters were divided, and the Israelites went through the sea on dry ground, with a wall of water on their right and on their left.
NIV
Moses did not actually part the seas, it was God.
Regardless, it is unclear where exactly this occurred (assuming that it did). It most likely occurred in the small inlet of the Red Sea called the Gulf of Suez today if it happened in the Red Sea. If it actually happened in a different body of water called the "Reed Sea", this could have been a tidal lake along the border between Egypt and the Sinai Peninsula.
God did not want to take the Hebrews in the short way along the sea, because he thought that they will run back if they will have to fight.
God took them through the desert, but still they would run back to Egypt because they wish to get the free food, meat and watermelon they had.
So God opened the sea, let them pass, and closed the Hebrews in the desert. They were protected from others but at the same time they were locked and could not return back to Egypt.
It's said God spilt the sea, and the Israelites walked across. Pharoh and his full army pursued them into the divide, but once the last Israelite crossed, the divide of water collapsed and swept away Pharoh and his entire army. Recent archeology has actually found remains of war chariots and ancient Egyptians weapons at the bottom of the Red Sea
Moses had to cross the Red Sea too, therefore by simple logic, he was not standing, but walking.
If you are asking where exactly the Red Sea crossing took place on a map, historians debate this and have proposed numerous locations (and that assumes that we narrow the field to those historians who consider the Exodus to be a historical event.)
Well, actually, Jehovah God parted the Red Sea. Moses led the people across. On the other side they sang praises to Jehovah, not to Moses.
