There are a total of 38 Riddler Trophies located on Miagani Island and they can be found in the following locations:
Riddler Trophy 01
Map Co-ordinates: 2648, 2713
Beneath Mercy Bridge on the support just north of mainland Miagani Island. You’ll find this in a small, make-shift room on the western side.
Riddler Trophy 02
Map Co-ordinates: 2722, 2666
Behind a weak wall on the north, water-facing side of the building with the large radio tower next to Mercy Bridge. Use Detective Mode to find the weak wall and then bring the Batmobile up onto Mercy Bridge. From here use the Batmobile to shoot the weak wall before heading over and climbing inside to find the Riddler Trophy.
Riddler Trophy 03
Map Co-ordinates: 2795, 2779
On a support on the eastern side at the end of Mercy Bridge, you’ll find a section of weak wall we can destroy with the Batmobile. Destroy this and climb up through the hole in the wall as Batman. From the entrance, you should be able to make out a Riddler Robot to the left and a Generator on the roof to the right.
Hit the generator to move the wall at the back of the room. Use the Voice Synthesizer on the Riddler Robot and have him move into the room where the door moved. Use repel on the Generator to destroy the Robot behind the door. Hit the ‘?’ to re-set the robot and then use the Voice Synthesizer once again on the Robot to have him step on the pressure plate to unlock the Riddler Trophy .
Riddler Trophy 04
Map Co-ordinates: 3144, 2990
Sitting on top of a mausoleum on the northern part of the cathedral.
Riddler Trophy 05
Map Co-ordinates: 3143, 2958
At the base of the Cathedral building, beside a pair of tunnels leading to Wayne Tower and Grand Avenue there is an anchor point that can be grabbed with the Power Winch with a weak wall above it. Destroy the weak wall to reveal an opening and then pull the anchor point out as much as possible to remove an obstacle.
Grapple up and inside as Batman and climb through the floor grating to nab the Riddler Trophy . Picking this up will summon a group of Riddler Robots. Switch back to the Batmobile and release the anchor point to crush the lot of them. Re-attach and pull back again so that Batman can escape.
Riddler Trophy 06
Map Co-ordinates: 3182, 2859
This Riddler Trophy is found at the very highest point of the Cathedral building in a small cage. The numbers ‘2887, 2171’ are written nearby. These are actually co-ordinates to a pressure plate located at Elliot Memorial Hospital on the northern corner of the roof. Stepping on this will trigger a countdown during which the cage holding the trophy will open. Make your way back to the Riddler Trophy location before time runs out to grab it.
Riddler Trophy 07
Map Co-ordinates: 3339, 2980
At the roadblock by the broken bridge on the eastern side of Miagani Island, just north of Wayne Tower. There is an anchor point here we can grab with the Power Winch , a pair of rotating gears and a tube on the right side containing the Riddler Trophy. Pull the anchor point out until both gears start rotating. Hop out of the Batmobile and use the Batclaw to snag the Riddler Trophy as it rises past the small gap in the pipe on the right.
Riddler Trophy 08
Map Co-ordinates: 3400, 2919
This one needs a little preparation before we can finally nab it. This is located behind a weak wall overlooking the water at the co-ordinates listed. To get at it, we’ll need to first break the wall. At the northwest corner of Wayne Tower, there is a ramp we can use to hop across to the base of the tower and drive all the way around to the northeast corner.
From here we should be able to shoot the wall. To actually reach the destroyed section of wall, we need to glide over and use the Line Launcher gadget to create a rope bridge between the wall just under the weak wall and the bridge support opposite. Alternatively, just land in the water near the hole in the wall and Batman might just grapple up into the alcove for you!
Riddler Trophy 09
Map Co-ordinates: 3581, 2823
About halfway up Wayne Tower is an open garden/viewing platform. There is an open fire escape here which we can enter, climb a few flights of stairs and find a Riddler Trophy on a table in a storage room.
Riddler Trophy 10
Map Co-ordinates: 3695, 2795
On the southern side of the Wayne Tower island compound you’ll find a green panel at ground level. This can be activated by using the Batmobile Forensics Scanner Pulse . This will create a trail of question marks that you will need to follow in Forensics Scanner mode a short distance, over the ramp to the north, and around the streets until you reach the Grand Avenue Station.
Here you’ll need to head inside and use the Remote Hacking Device on a panel by the shutter to allow the Batmobile access. The question marks will lead you to a green target we can shoot on a wall just Inside Grand Avenue Station. Doing so will earn you a Riddler Trophy .
Riddler Trophy 11
Map Co-ordinates: 3429, 2597
On the western and eastern facing side of this building are two large windows about half way up. Glide and crash through these from another building nearby to find the Riddler Trophy within.

This weak wall is made of wood panelling, so we can fly into it to destroy it. Climb to the roof directly above it, glide off the rooftop and immediately pull a 180 degree turn and fly into the boards to knock them down. Inside you’ll find the Riddler Trophy .
Riddler Trophy 20
Map Co-ordinates: 3155, 2472
Fly through the ring of the giant donut in the ‘Dang-Good Donut’ sign on Grand Avenue. You can’t grapple this area, so you will need to either glide down and in from a point above, or use the Batmobile eject and flying in from there. You’ll find the Riddler Trophy on the floor inside.
Riddler Trophy 21
Map Co-ordinates: 3060, 2389
At the base of the building specified by the co-ordinates you’ll find a Power Winch puzzle. There is a pair of anchor points we need to use to get the ball with the Riddler Trophy to ground level. Pull the anchor point to the left until the ball drops, then drag it all the way to the right until it drops again. Grab the lower anchor point and pull that to the right and then all the way back to the left until the ball reaches the bottom. At that point, run over and grab the Riddler Trophy!
Riddler Trophy 22

You’ll find the next one on top of the ‘Gotham Herald’ Building. There is a group of six Riddler Robots guarding it. Note that you can only attack the green Robots, attacking the red ones will cause you to take damage similar to a shock stick effect. You can change the colours of the Robots from green to red and vice versa by hitting the ‘?’ at the back of the area with a quick-fire Batarang . After defeating all of the Robots, you can grab the Riddler Trophy from the cage on the wall with the Batclaw .
Riddler Trophy 24

Riddler Trophy 25
Map Co-ordinates: 2830, 2457
This rooftop location features a caged Riddler Trophy with a junction box next to it that requires the Batmobile Power Winch to activate. Make your way to the parking garage to the southeast and on the top floor you’ll find a ramp. Use your Afterburner to hit the ramp and you’ll leap across to another building – from here you are in range of the junction box so power it up, then switch to batman to collect the prize.
Riddler Trophy 26
Map Co-ordinates: 2871, 2070
Beneath Penitence Bridge there is a Riddler Trophy in a cage, a pressure plate next to it and on the platform below a Riddler Robot and a second pressure plate. There are also four question marks that will light up and you’ll need to hit all four of them within 3 seconds of one another to nab the Riddler Trophy .
To set this up, use the Voice Synthesizer to have the Riddler Robot stand on the lower pressure plate. This will light up a pair of question marks on the bridge support above. Climb up and plant Explosive Gel on both of these. Now have Batman stand on the upper pressure plate – this should light up the final question mark ahead.
From Batman’s position on the pressure plate you can see a pair of question marks, both of which are in Batarang range and we can hit with quick-fire Batarangs . Do so and then quickly look to the pillar and detonate both Explosive Gel placements to complete the challenge.
Riddler Trophy 27
Map Co-ordinates: 3015, 2158
You’ll find a green panel at ground level at the base of Elliot Memorial Hospital at the co-ordinates listed. This can be activated by using the Batmobile Forensics Scanner Pulse . This will create a trail of question marks that you will need to follow in Forensics Scanner mode a short distance, up the nearby overpass and down to the street below.
The question marks will lead you to a green target we can shoot on a wall just next to the ‘Jenna’s Furniture’ and ‘Cuffs’ signs (at 2866, 2201 ). Grapple up to the small hole you just created in the wall of the small bridge building to find a Riddler Trophy inside.
