To the west of camp lies Berkeley, California. If you're lucky, you may get a weekend furlough here, or at least a free afternoon, but only if you've finished all your drills, polished your armor, and dug a few miles of trenches. Get back to work, Roman!
The Caldecott allows car traffic to flow through the Berkeley Hills, but a secret middle tunnel will lead you into Camp Jupiter. This passage is guarded at all times, so if you see Roman soldiers standing by the highway in the middle of rush hour, you probably caught a glimpse through the Mist.
This is the back entrance to the camp. It's normally only used for new recruits coming through the Caldecott Tunnel, or for sneaking out for late night trips to New Rome. That behavior is strongly discouraged, but common.
This is the main orth-south road in camp, where you can find all kinds of shops and cafes catering to the legion. Need your gladius repaired, or want to buy a cup of coffee from Bombilo the two-headed barista? This is the place to go.
Work hard, eat well! The mess hall is arranged Roman style with low comfortable couches. The food is excellent, delivered by attentive wind spirits. Each cohort is assigned an area, but feel free to move around and mingle. Just watch out for flying pizzas. 
Camp headquarters, this doubles as the praetors' office, the treasury for all the legion's magical goodies, and the shrine for its various banners and symbols. Unless Reyna sent for you, don't invite yourself in. Her dogs are not friendly. 
The poor Fifth Cohort is situated away from the other barracks, next to the stables and the compost heap. The Fifth has had a bad reputation for years, so if you join, prepare to be picked on. It's not all gloom, though. You're closer to the mess hall! 
The Romans are famous for their baths, and even the legion gets to indulge! After a hard day pummeling your enemy with swords and cleaning the unicorn stables, you'll appreciate the swimming pool, sauna, and spa.
This is the main entrance to the camp, and it's guarded with scorpion ballista, so don't show up unannounced.
The main road into camp runs between the barracks, straight to the headquarters. Going the other way, it will take you into New Rome. Just be aware of begging fauns along the roadside. 
The legionnaires are divided into five cohorts, each with its own barracks – girls on one side, boys on the other. The legion isn't big on comfort, but the bunks aren't too bad, and you can always reuse your bed sheet as a toga! 
Named after the Tiber River of Ancient Rome, the Little Tiber may be small, but it's full of power. It acts as a boundary to keep out undesirables like monsters, salesmen, and Greeks. No one quite knows where the Little Tiber originates, nor where the water goes once it reaches the lake. Some say it flows to and from the Underworld, or from the mists of time, but no one who has tried to find the source has ever returned. 
The Oakland Hills form the south border of camp. They are patrolled by Lupa's wolves and the lares, ancestral ghosts of Rome. It's a toss up which would be more dangerous to meet. 
The Berkeley Hills form the northern border of camp. To most mortals, the valley with Camp Jupiter is invisible, but if you know where you're going, you can find your way overland into demigod territory. Just be warned: trespassers will be punished with extreme prejudice. 
Why does New Rome need an aqueduct if it's next to a lake and a river? The aqueduct provided running water straight from the secret springs of the Berkeley Hills naiads. The naiad water isn't quite as powerful as godly nectar, but it does have mild magical properties. It does amazing things for acne.
Like Rome, only newer! In New Rome, demigods can live in peace, study at the local university, or even get married and start a family. Many graduates of the legion retire here. The hills have wonderful gardens, winding cobblestone streets and cozy townhouses. The Forum area has a lively nightlife and lots of entertainment options. A great place to visit or settle down, but it's only open to Roman demigods. Sorry, mortals!
As it did in ancient times, the Pomerian Line marks the borders of the city of Rome. Inside the line, weapons are strictly prohibited and the laws are enforced by Terminus, god of borders. He can be a little hard to get along with, but he does keep things running smoothly.
All official business is decided at the Senate House, where the elected representatives from the legion come together to vote on important matters. The Senate is a civilian body, but officers of the legion often hold important senate positions as well. Normally two consuls run the senate, and each consul has veto power over the other. Does this ever lead to a fight? Only a lot! 
The center of life in New Rome, the forum is a beautiful plaza with statues and fountains, lined with shops that will sell you anything from ambrosia and a blueberry muffin to a new toga and winged sandals. Everybody stops by the forum eventually. It's the place to be seen! 
Come try your skills at the gladiator fights, monster simulations, or the mock naval battles when they flood the coliseum floor and turn it into a lake. Tickets go fast, and be careful not to sit in the splash zone, or the explosion zone, unless you're feeling lucky. 
Who doesn't love a good chariot race? At the Circus Maximus, you can race for glory, or merely enjoy the excitement from the stands. Want to see which is faster – a fire-breathing horse or a bronze lion? This is the place to go! 
A popular destination for picnics and boating competitions, it's also a great place to throw criminals, usually after sewing them into a sack full of weasels. Crime really isn't much of a problem in New Rome.
All the gods of Rome are represented on Temple Hill, which is wisely located outside the city limits just in case the gods decide to quarrel and blow up each other's monuments. You can leave offerings or ask for help at any of the many temples, but be warned: you never know whom you'll meet. It could be another camper, a god in disguise, or a vicious spirit from the Underworld. Don't you love surprises?
The temple of Pluto doesn't look like much, but it's still a place of great power. You'll see that the roof is littered with bones and diamonds. I wouldn't think about stealing those diamonds if I were you. Otherwise you'll end up among the bones. 
The Roman goddess of war, because you can never have enough war gods, right? Bellona oversaw the foreign policy of the Roman Empire, especially when it came to smashing their enemies. Her temple has a special field of dirt that represents foreign soil. When war is declared, the Romans symbolically throw a spear into that dirt. That may not sound very scary, but wait until the legion shows up on your doorstep. 
Mars the Avenger was not just a blustery god of war. He was one of the patron gods of Rome. After all, he was the dad of Romulus and Remus in some accounts. His temple is part weapon display, part fortress, all blood red. 
The most important temple on the hill is dedicated to Jupiter, the Best and the Greatest. It's an open-air pavilion with a huge gold dome and a gold statue of the Big Guy himself. This is where augurs have read the fortunes of Rome for eons. If you go, bring your lightning rod.
On a clear day, you can see this inland mountain from Camp Jupiter. Mount Diablo has an evil reputation. Until recently, it was the home of the fire-breathing giant Enceladus.
Part battlefield, part party zone, the Field of Mars is where everything happens – deathball, marching drills, war games, and the occasional monster hunt. The legionnaires build a new fortress each time they play war games, so the assault is never the same twice. Feel free to explore, but look out for trenches, hidden tunnels, and charging elephants.
