The Blocked Cave is one of those simple side quests that you can complete easily in Zelda: Tears of the Kingdom. To initiate this side quest, you can go north from the Hebra Trailhead Lodge and along the way, you will come to meet a Rito NPC named Mazli.
Mazli will face some trouble, as the cave where he used to store his food has been blocked by a giant rock. So, after interacting with him, you can begin the Blocked Cave side quest.

To start the Blocked Cave side quest in Zelda: TotK, you will have to venture north from the Hebra Trail.
Keep heading north, and finally, you will reach a snowy path with some thorns. After crossing it, you can go to these precise coordinates (-3584, 2471, 0228).
Once you cross the path, you will see an NPC at the end. This NPC’s name is Mazli in Totk. He will be distressed, and after interacting with him, you will learn that a huge boulder seems to be blocking his entrance to the cave.
Since he forgot to pick some bomb flowers, you can opt to help him out. This way the Blocked Cave side quest will then be made available for you.
Destroy the Boulders Blocking the Cave
Once you accept The Blocked Cave side quest, you will learn that there is no other way inside the cave other than to destroy the boulders at its entrance.
So, you will have to remove the boulder to complete this side quest. Now, there are two ways that you can use to complete this side quest in the game.
This is the traditional method as hinted before by Mazli himself that you can use Bomb flowers to simply blow the rock into pieces.
To do so, you will need to find them by exploring the nearby caves. You will be able to salvage 2 bomb flowers from the Hebra South Summit Cave, which can be found on the east side.
After acquiring them, you can return to Mazli to take care of the rock problem.
Attach the bomb flowers to your arrow and target the Giant boulder blocking the entrance to the cave.
It will take at least two shots to break the rock covering the entrance and once you have completed the task you can go back and meet Mazli.
If you don’t have any bomb flowers, you can start by choosing any sword of your choice. For instance, you can choose Boko Reaper, Feathered Edge, Rusty Claymore, etc.
Then, you can use the Fuse ability to select a nearby rock and fuse that with the sword you selected before, forming a Rock Hammer.
You can simply proceed to the cave entrance and start slashing the giant rock with your fused weapon.
Little by little, the giant boulder will start breaking into bits, and you will also end up salvaging some Opal and Rusty Claymore during this endeavor as well.
Keep at it, and you will be able to break the giant boulder with relative ease. You can do it faster if you start from one side and continue slashing from there onward.
It will take around 40 strikes to break the giant rock and clear the entrance. Moreover, if your rock hammer breaks you can go back and fuse another rock with the sword and come back to finish the task.
Quest Reward
After opening the path to the cave, you can go back to speak with Mazli. He will be overjoyed and will thank you for helping him.
Lastly, he will also reward you with a Red Rupee (20 Rupees). This way, The Blocked Cave side quest will be marked complete in the Legend of Zelda: Tears of the Kingdom.
