Blue dragons in OSRS are monsters with valuable drops, and often are assigned as a Slayer task after the completion of the quest ‘Dragon Slayer I.’ They are guaranteed to drop blue dragonhides and dragon bones, which are both quite valuable as guaranteed drops. 

Keep in mind, however, that the prices of these items tend to fluctuate on the Grand Exchange. While I don’t foresee their prices dropping to a point they’re no longer valuable, I would recommend keeping an eye on their valuations if you plan on collecting these items.

Of course, blue dragons are found in a variety of locations across Gielinor. Some of these locations are better than others in terms of accessibility, danger, and the number of dragons that can be found there. In this guide, I’ll show you the best place to find blue dragons in OSRS. 


Before heading to the best places to find blue dragons, you need to make some preparations. Namely, you need an anti-dragon shield or antifire potion, both of which require completion of ‘Dragon Slayer I.’ You will go to Crandor during this quest, as well.


Completion of this quest is also a requirement to be assigned dragons of any type as a Slayer task. You can start Dragon Slayer I by talking to the Guildmaster outside the Champion’s Guild, just southwest of Varrock. You need 32 Quest points to start the quest.

Also, the anti-dragon shield is much cheaper and more accessible than antifire potions. You will be given one during the quest, and you can get another from Duke Horatio in the Lumbridge Castle if you lose it. 

Taverly Dungeon

In terms of the best place to find blue dragons in OSRS, I should talk about the most commonly used location, which is the Taverly Dungeon. This is a large and expansive dungeon, and you will need a dusty key to access the area containing nine blue dragons.


If you don’t have the dusty key yet, you can get it from Velrak the Explorer, who is imprisoned within the Black Knight’s Headquarters in the southern part of the dungeon. You must kill the jailer first for a key to Velrak’s cell, then talk to Velrak. 

It is very important to NOT ask Velrak for a reward, and he will give you the dusty key, which unlocks the gate between the lesser demon area and the blue dragon area. If you have ‘Legend’s Quest’ complete, you can also buy dusty keys from the Legends’ Guild for one coin. 

Alternatively, you can bypass the dusty key requirement with 70 Agility, by climbing through the pipe right next to the dungeon entrance. When you come out the other side, you will be among the blue dragons. 

The Taverly Dungeon also contains an upper floor area with more blue dragons, containing twelve dragons. However, you must be on a Slayer task to attack the blue dragons up here. There is a staircase just north of the dungeon’s entrance. 

Corsair Cove Dungeon

While the Taverly Dungeon is the best place to find blue dragons, there are several honorable mention alternatives. One example of these is the Corsair Cove Dungeon, which contains five blue dragons. 

To access the section of the Corsair Cove Dungeon with the dragons, you need to complete the quest ‘Dragon Slayer II.’ It’s a very long and very difficult quest, but this and other rewards from it are very worth it.

You can start Dragon Slayer II by talking to Alec Kincade outside the Myth’s Guild. You need 200 Quest Points, 75 Magic, 70 Smithing, 68 Mining, 62 Crafting, 60 Agility, 60 Thieving, 50 Construction, and 50 Hitpoints for this quest. 

Ogre Enclave

Another honorable mention for the best place to find blue dragons in OSRS is the Ogre Enclave, which contains six dragons and can be accessed during and after the quest ‘Watchtower.’ This is a much shorter and easier quest than Dragon Slayer II. 

You can start Watchtower by speaking to the Watchtower Wizard on the second floor of the Watchtower. You will need to climb the nearby trellis to get up here. To do the quest, you will need 14 Magic, 15 Thieving, 25 Agility, 14 Herblore, and 40 Mining. 


In addition to honorable mention locations, there are a number of alternative monsters that count as blue dragons for the purposes of a Slayer task. First, baby blue dragons are much weaker, and therefore much quicker and easier to kill, than their adult counterparts.

To do this quest, you will need 14 Magic, 15 Thieving, 25 Agility, 14 Herblore, and 40 Mining.

Alternate Variants

In addition to honorable mentions of places to find blue dragons in OSRS, there are several alternative variants of the monster that still count as blue dragons for the purposes of a Slayer task.

The first of these alternate variants is the baby blue dragons, which are much weaker, and therefore much quicker and easier to kill than their adult counterparts. They can be found near these adult counterparts in the Taverly Dungeon, Corsair Cove Dungeon, and the Isle of Souls Dungeon, which can be accessed via portals in Edgeville and the Ferox Enclave. 

The second of these alternative blue dragon variants is Vorkath, a very powerful boss dragon who can be fought after completing Dragon Slayer II. To fight Vorkath, talk to Torfinn on the docks in Rellekka, and he will sail you to Ungael. This is very close to Waterbirth Island.


You can fight Vorkath on Ungael, but keep in mind that he is a very, very powerful boss-level monster. You will have already fought and defeated him once during Dragon Slayer II, and the mechanics of the fight remain the same, but his stats are much, much higher after the quest. 

Many players who have the means choose to fight Vorkath instead of regular blue dragons on a Slayer task, since Vorkath has a ton of incredibly valuable drops due to his status as a boss monster. 

Final Thoughts

There are several great places to find blue dragons in Old School RuneScape. The best place is the Taverly Dungeon, which contains the most dragons compared to other locations. Honorable mentions include Corsair Cove Dungeon and the Ogre Enclave.

You can also fight either baby blue dragons or Vorkath as alternate variants to a blue dragon Slayer task. Baby blue dragons can be found near adults in the Taverly, Corsair Cove, and Isle of Souls Dungeons, while Vorkath must be fought on Ungael.
