|First Appearance/Mention:||The Inspector's Mad Holiday|
Bolaron was a planet described by the Encyclopaedia Cosmosica as the "quietest place in the universe". It was also renowned for its tea.
It was a running gag in the Third Inspector's era that he often tried to go to Bolaron, but the BOOTH always led him to the Sergeant. Eventually, he and Yosif landed on Bolaron, but they had to fight against werewolf-like creatures. On leaving the planet, the Inspector declared it was "the worst holiday ever" and that the Bolaronian tea was overrated, swearing he would never come there again.
