Look at a globe. Focus on that jagged, narrow strip of blue separating Africa from Asia. That's it. If you're wondering exactly where is Red Sea on a map, you need to look right between the northeastern corner of Africa and the Arabian Peninsula. It's a long, skinny inlet of the Indian Ocean, stretching about 1,200 miles from north to south. It looks like a giant crack in the earth's crust because, well, that's exactly what it is.
The Red Sea isn't just some random body of water. It’s a tectonic rift.
The African Plate and the Arabian Plate are slowly pulling away from each other. They’ve been doing this for millions of years. This movement created a deep, salt-filled basin that connects to the ocean at the south through the Bab el-Mandeb strait and the Gulf of Aden. To the north, it splits into two "fingers"—the Gulf of Suez and the Gulf of Aqaba—which hug the Sinai Peninsula. Honestly, it’s one of the most recognizable shapes on the planet if you know what to look for.
Pinpointing the Red Sea: Borders and Neighbors
So, who actually lives next door? When you find where is Red Sea on a map, you’ll see it’s bordered by six different countries. On the eastern side, you have Saudi Arabia and Yemen. To the west, you’re looking at Egypt, Sudan, and Eritrea. Tucked right at the very north, past the Sinai, you’ll find the coastlines of Israel and Jordan.
It’s crowded.
The geography here is wild. Most of the land surrounding the water is harsh, blistering desert. Think of the Sahara to the west and the Arabian Desert to the east. This isolation is why the water is so unique. There are no major rivers flowing into the Red Sea. None. Because no fresh water or silt comes in from rivers, the visibility is insanely clear. It’s a diver’s dream. But because there’s no inflow and the sun is constantly baking the surface, evaporation is high. This makes it one of the saltiest bodies of water on the globe.
Northern Landmarks
The Suez Canal is the big one. It’s a man-made miracle connecting the Mediterranean Sea to the Red Sea via the Gulf of Suez. Without it, ships would have to sail all the way around the tip of Africa just to get to Europe. Then you have the Gulf of Aqaba. It’s deeper and narrower, home to the famous resort towns of Sharm El-Sheikh and Eilat.
Southern Landmarks
At the bottom, things get tight. The Bab el-Mandeb strait is often called the "Gate of Tears." It’s a narrow chokepoint between Djibouti and Yemen. It’s only about 18 miles wide at its narrowest point. This is where the Red Sea finally breathes into the Indian Ocean.
Why Is It Actually Called the "Red" Sea?
It’s blue. Extremely blue. So why the name?
There are a few theories, and historians still argue about it. The most common scientific explanation involves a type of cyanobacteria called Trichodesmium erythraeum. That’s a mouthful. Basically, it’s a type of algae. When these blooms die off, they turn the normally turquoise water a reddish-brown hue. It doesn't happen everywhere or all the time, but it’s striking when it does.

Other people think it’s about the mountains. The ancient Egyptians called the desert to the east the "red land." Some scholars, like those who study ancient Semitic languages, suggest that "red" might have been a way to designate "South," just as "Black" (as in the Black Sea) might have designated "North" in certain cardinal color systems.
Then there’s the biblical narrative. You can’t talk about the Red Sea without mentioning the Exodus. Whether you view it as historical fact or religious tradition, the story of the parting of the "Sea of Reeds" (the literal translation of Yam Suph) has cemented this location in global consciousness for millennia.
The Hidden Geography: What's Under the Surface?
If you could drain the water, you’d see a jagged landscape. The Red Sea is deep. In the center, the "axial trough" reaches depths of over 9,000 feet. It’s a volcanic environment. There are literal hydrothermal vents on the sea floor spitting out hot, mineral-rich water.
- Coral Reefs: These aren't just any reefs. The Red Sea fringing reefs are over 5,000 years old.
- Endemic Species: About 10% of the fish you see here can't be found anywhere else on Earth.
- The Blue Hole: Located near Dahab, Egypt, this is a submarine sinkhole that drops straight down. It’s beautiful and incredibly dangerous for inexperienced divers.
The water temperature stays warm year-round. Even in the depths, it rarely drops below 70°F (21°C). This warmth, combined with the high salinity, creates a pressurized environment that supports massive biodiversity. You’ve got hammerhead sharks, dugongs (sea cows), and manta rays all chilling in this narrow corridor.
How to Find the Red Sea in Different Map Views
If you’re looking at a topographical map, look for the massive Rift Valley. The Red Sea is essentially the flooded part of the Great Rift Valley system that stretches down into East Africa. It’s a literal tear in the Earth.

On a political map, it serves as a massive liquid border. It separates the African continent from the Middle East. It’s the reason Egypt is often called a "transcontinental" country, as it owns the Sinai Peninsula which sits on the Asian side of the water.
On a satellite view (like Google Earth), the Red Sea stands out because of the contrast. You have the deep indigo of the central trench, the bright neon turquoise of the shallow coral reefs, and the stark, burnt-orange sands of the surrounding deserts. It’s one of the few places on Earth where the desert meets the sea with almost zero transition zone. No lush green forests here—just sand, then suddenly, vibrant coral.
The Economic Heartbeat of the World
The Red Sea is one of the busiest shipping lanes on the planet. Around 10% to 12% of global trade passes through here. Every day, massive tankers carrying millions of barrels of oil and thousands of shipping containers move through the Suez Canal.
It’s a geopolitical hotspot. Because the waterway is so narrow, any instability in the surrounding countries—like the ongoing conflicts in Yemen or tensions near the Suez—can send global gas prices skyrocketing. It’s a fragile artery.
Essential Travel Hubs
If you're planning to visit, you'll likely fly into one of these spots:
- Hurghada, Egypt: A massive hub for European tourists looking for sun.
- Jeddah, Saudi Arabia: A historic gateway city that is rapidly becoming a luxury tourism destination.
- Marsa Alam, Egypt: Further south and much quieter, great for seeing sea turtles.
- Aqaba, Jordan: The only way for Jordan to access the sea, located right next to the border with Israel.
Beyond the Map: Real-World Insights
Understanding where is Red Sea on a map is just the start. You have to realize that this sea is changing. Because it’s so salty and warm, scientists are studying Red Sea corals very closely. Why? Because these corals seem to be more resistant to climate change than those in the Great Barrier Reef. They are "tougher." They’ve evolved to handle heat that would kill other reefs.
If you are a traveler or a student of history, the Red Sea is more than a coordinate. It's the link between the Mediterranean and the Indian Ocean. It's the path of ancient spice routes. It’s the reason the British Empire was so obsessed with controlling Egypt in the 1800s.
Actionable Steps for Your Search:
- Use Coordinates: If you're using a GPS or digital map, look for $20^\circ N, 38^\circ E$. That puts you right in the middle of the water.
- Check the Tides: If you're visiting, remember that the Red Sea has a very small tidal range. Unlike the Atlantic, the water level doesn't change drastically throughout the day.
- Verify Regional Safety: Always check current travel advisories for the southern end of the sea (near Yemen) versus the northern end (Egypt and Jordan), as the political climate can shift quickly.
- Satellite Comparison: Open a map app and toggle between "Map" and "Satellite." Notice how the coral reefs appear as light-colored "shelves" right along the coastline of the Sinai and Saudi Arabia.
The Red Sea remains one of the most strategically and biologically significant places on the map. Whether you're looking for a diving spot or studying global trade, this narrow slit of water is the key to understanding the connection between Africa and Asia. Over time, as the plates continue to drift, this "sea" will eventually become a vast ocean, but for now, it's our planet's most spectacular salt-water corridor.
