This guide will let you know about the top 5 Jailbreak secrets found in the Drone update.
# 5
Secret hidden skeleton
For the first secret, you will need to make your way over and get any helicopter. It is suggested to use a small helicopter for this secret.
Next, once you have a helicopter, head over to the max security prison, don’t land or go inside the prison; instead, head past the invisible border.
Once outside, you have to fly down with your helicopter.
Then you will be under the jailbreak map with a helicopter. Next, fly your helicopter over to the large rock beside the prison cell. 
You have to land your helicopter near the edge on the right side of the cells. Once lined up, exit the helicopter and enter any passenger seat.
After that, lower the rope, and you will be put in the prison wall, and you will see a skeleton hidden inside the wall.
This secret is very cool since it is only visible from outside the map. But if you want to exit, walk back inside the map through the wall, and you will be back inside. The only way to return is with a rope and helicopter, remember to line yourself, or you will fail at getting inside.
#4 hidden waterfall cave
For the next secret, you have to head to the waterfall beside the donut shop. Once here, exit your vehicle and head to the waterfall. 
Swim into the small crack between the hill and the weird ground; it is a fairly small opening that might take some time. Once inside, there is a large opening that you can swim around in. This secret cave is great for hiding from players if you have a bounty. You can also shoot from inside the cave without anyone knowing who; since this place is unknown, not many people would think you are down in a cave.
It is recommended to go there if you have a fairly large bounty and need to go AFK.
#3
Hidden RB battle season 2 badge
You first need to head to a gun shop for this next secret and grab any weapon you want.
Once you have your weapon, head to the bank and climb the back ladder.
You can either grab a helicopter or jump down to the flag.
But once at the flag, you will find a secret RB battle badge on the pole.
Next, shoot the little symbol with any gun you currently have, and then shoot the red box on the building that looks like a target.
Once you get a message saying no sword and a clue to the location, you will also get a secret badge for the RB battle season 2 event. This secret was very well thought out and hidden. It is still cool to see they at least put effort into a secret. Just remember to shoot the flag and then the target on the building.
# 2
Secret working garage
For the next secret, first head to the airport on any vehicle you own. Once you reach there, either drive inside or walk to the hanger on the far left.
You will get the garage to open, and you can spawn any vehicle.
It is a very strange secret inside the game which is hidden. You can do anything like a normal garage, with spawning and customizing. It originally only worked to customize planes, but now it works with all vehicles.
#1 Secret OG star
You will need to go to the raised bridge located near the power plant for this final secret.
Once you reach there, exit your vehicle and head to the waterfall on the right.
After that, head inside the waterfall and move to the hidden cave. There will be a glowing star in a stone patch of the cave, you can not interact with the star, but you can stand on the top.
This secret is fairly known, but it has a cool backstory which makes it a secret. The star used to be located beside the road leading to the new airport.
It has been inside the game since 2017, which makes it important to history.
