Achievement Diaries in OSRS provide players a sort of to-do list of content to experience and engage with, broken up by in-game regions. Twelve regions in the game have Achievement Diaries, and each of those twelve is broken up into four difficulty tiers.
These tiers include Easy, Medium, Hard, and Elite. Of course, each of these tiers has quest and skill requirements corresponding to its difficulty. For example, the Ardougne Easy Diary requires two beginner quests, while the medium Diary requires thirteen quests of varying difficulty.
Moreover, each Diary and tier of Diary has its own rewards, including a specific item, and various quality of life improvements. However, some of these rewards are more useful than others, and based on that criteria, I will be describing the best Diaries to do in OSRS.
The first candidate for the best diaries to do in OSRS is the Ardougne Diary. In fact, its rewards are so good that I recommend rushing the Ardougne Easy Diary as early as possible into a fresh account, due to its rewards and very low requirements.
For the Ardougne Easy Diary, you only need 5 Thieving, and to have completed the quests ‘Biohazard’ and ‘Rune Mysteries.’
You can start ‘Biohazard’ after completing ‘Plague City’ by speaking to Elena in her house in the northern part of East Ardougne, and you can start ‘Rune Mysteries’ by speaking to Duke Horatio on the second floor of Lumbridge Castle.
When you complete the Ardougne Easy Diary, you will get an Ardougne Cloak 1, which offers unlimited teleports to the Kandarin Monastery, just south of the Ardougne Zoo. This teleport is very close to both a Spirit Tree and Fairy Ring, making it incredibly useful for low levels.
In terms of quality of life rewards, you will get double the amount of Death Runes when trading in adult cats to West Ardougne’s citizens, a 10% increased chance of stealing successfully from Ardougne’s market stalls, and noted drops from Jubsters and Frogeels at the Tower of Life.

Rewards from Ardougne Medium stack with those from Easy, and this is true for all Diaries and their rewards. The Ardougne Cloak 2 will be bestowed upon you, which offers three teleports per day to the Farming patches north of East Ardougne.
Other rewards include 100 free pure essence per day, a 10% increased chance to pickpocket successfully in East Ardougne, extra runes when Runecrafting at the Ourania Altar, noted drops from Unicows, Newtroosts, and Spidines at the Tower of Life, and a Ring of Life toggle to Ardougne.

Along with the best diaries to do in OSRS, I will also make a few honorable mentions, the first of which being the Falador Hard Diary. This is a great Diary to complete for its rewards, the Falador Shield 3, which offers a daily full Prayer restore, and can locate the Giant Mole in its tunnels, making this fight significantly less tedious.
