Quick Links
Before players get too far ahead in their Breath of the Wild journey, they'll want to grab the Camera Rune for the Sheikah Slate. As its name indicates, this allows Link to take pictures of just about anything. This comes in handy when registering items to the Hyrule Compendium. The Camera Rune is also a necessity for completing several side quests and Shrine Quests.
The "Leviathan Bones" side quest will have Link traveling to three different regions of Hyrule. He'll need to take pictures of the leviathan bones found in the Hebra, Eldin, and Gerudo regions. While it's far from Breath of the Wild's more difficult side quests, only one set of the bones are in plain sight. The remaining two will require some puzzle-solving.
How to Unlock "Leviathan Bones" Side Quest
"Leviathan Bones" is unlocked at the Serenne Stable. This can be reached by heading east from Rito Village, north from Ridgeland Tower, or west from Woodland Tower. In order for Serenne Stable to be visible on the map, players will need to Activate the Woodland Tower.
Look for three NPCs by the names of Garshon, Onya, and Akrah. They're conducting research on the three leviathan bones around Hyrule, and speaking to them adds "Leviathan Bones" to the side quest list. All three of them need a perfect image of each of the leviathans' skulls.
Obtaining a picture can be done with the help of the Sheikah Slate's Camera Rune. This is obtained from the Hateno Ancient Tech Lab after speaking to Purah. Without it, Link won't be able to complete the side quest.
Hebra Great Skeleton Location
The Hebra Great Skeleton is the closest of the three Leviathan Bones. Players will want to head northwest from the Hebra Summit. This will take them to a slope with a stone door. Beyond this are the bones as well as the To Quomo Shrine. Unfortunately, no amount of bombs or stasis is going to grant Link entry. Instead, he'll need to use a snowball. Go to the top of the hill, and there should be snowballs to roll down the hill and crash into the door.
Equip cold-resistant gear like the Snowquill Set when venturing out into the Hebra Region . Equipping a flame weapon will ward off the cold, too.
How to Get Inside the Ruins
It's recommended to Activate the Hebra Tower to make the map visible to players. Zoom in on the map as far as it can go, and look for the Hebra North Summit. The Hebra Great Skeleton and To Quomo Shrine are located inside the summit.
If players look closely, they can see a puddle of water. Use Cryonisis to build two iceblocks with some space between them so that the snowball can roll down the path without getting stuck in the ravine.
From where it says START on the above image, toss one of the snowballs in the direction of the blue line so that it rolls over the Cryonisis blocks. If this is done properly, the snowball should grow large enough to break down the door when it reaches the bottom of the slopes.
Head inside where it says RUINS ENTRANCE (on the above image) and continue along the path until Link sees the Hebra Great Skeleton. Switch the Sheikah Rune to the Camera Rune and get a picture of the skeleton. Remember that it must have the head visible. Otherwise, it won't count and Link will need to return to get a better picture.
Be sure to Activate the To Quomo Shrine and get the Spirit Orb within.
Gerudo Great Skeleton Location
The Gerudo Great Skeleton is in the far southwest of Gerudo Wasteland. For this one, Link is going to need the help of a Sand Seal. There are two Sand Seals outside Gerudo Town. Equip gear that raises Stealth (like the Stealth Set) and sneak up on the Sand Seals. When Link is close enough that the Action Button says Grab, press A-button to catch the Sand Seal.
If players are still struggling to wrangle a Sand Seal, then they can hit one with a Bomb or Bomb Arrow to stun it first.
Also, players will want to equip a Shield with low Guard . When sand surfing, Link uses whatever Shield he has equipped as a board. Just like Shield Surfing, sand surfing will wear away at the Shield's durability.
If players already have the Gerudo Set and can get into Gerudo Town, then they can speak with a Sand Seal vendor at the western entrance. Renting a Sand Seal costs 50 rupees, but a rented one will not run off if Link loses his grip.
Equip heat-resistant gear like the Gerudo or Voe Set when venturing out into the Hebra Region. Equipping an ice weapon will ward off the heat, too.
How to Reach the Gerudo Great Skeleton
From Gerudo Town, take a Sand Seal southwest of town (refer to the yellow arrow for the direction). As Link distances himself from Gerudo Town, the map will become staticky and the desert sands will obscure the screen, making it near-impossible to see. When this happens, don't panic; keep the Sand Seal in the same direction (southwest).
When the map shows static, Link will not be able to warp .
Fortunately, the Sheikah Sensor will still be functioning. There is a Sheikah Shrine (Hawa Koth) under the Gerudo Great Skeleton and a Great Fairy Fountain. Follow the sounds of the radar if necessary. When Link is close enough to the Gerudo Skeleton, the sandstorm will subside.
Once there, Activate the Shrine and get the Spirit Orb. Players will need to come back to this area for a later side quest, so it's best to register it as a Travel Point now. Then, climb the left wall so that Link is almost eye-level with the Gerudo Skeleton's head. Take a picture with the Camera Rune.
Eldin Great Skeleton Location
The Eldin Great Skeleton is at the north rim of Hyrule. The best way to reach this skeleton is to Fast Travel to the Shora Hah Shrine. This Shrine is north of the Abandoned North Shrine of Goron City. It's also the place where players meet and rescue Yunobo, Daruk's descendent.
Look for the giant lake of lava, and there will be a giant skull. Inside that skull is the Shora Hah Shrine. Players will want to glide towards it and make sure to land on the skull. Another way of reaching this Shrine is to use the minecart and the rails further up the lava river, but this is quicker albeit more dangerous.
Equip flame-resistant gear such as the Flamebreaker Set when entering the Eldin Region. If players don't have this, then they can buy Flameproof Elixirs from the Foothill Stable .
Climb up the Shora Hah Shrine's skull and glide north. Climb up the wall here, and then head north again to the Eldin Great Skeleton next to the East Deplian Badlands. Unlike the Hebra and Gerudo Great Skeleton, the Eldin Great Skeleton is home to black and silver Bokoblins, Moblins, and Lizalfos.
Link can sneak around the Great Skeleton while wearing stealth-enhancing gear, but if he's visiting during the day, then it's likely a monster will spot him first. The best time to infiltrate the Eldin Great Skeleton is at night while the monsters are asleep. Another method is to equip Majora's Mask. This will prevent Bokoblins, Moblins, and Lizalfos from attacking Link. However, Majora's Mask Expansion Pass, meaning it won't appear at the Kolomo Garrison Ruins if players don't have the DLC.
Those that are just here for the skeleton's picture should stand far enough away and use the Camera Rune. Unlike the last two skeletons, this one doesn't have a Shrine. If for some reason players wish to visit the Eldin Great Skeleton again, they'll have to warp back to the Shora Hah Shrine.
"Leviathan Bones" Side Quest Reward
Warp back to Serenne Stable and track down the three researchers. Show each of them the requested photo. Once they've all seen the Leviathan Bones, they'll give Link 300 Rupees as thanks.
