It is the oldest and the most worn-looking of the cabins; this is due to its former use as a home for all unclaimed demigods, as well as the children of the minor gods. Its dull brown paint is chipped off (it really should be repainted) and there is a caduceus overhanging the door. In the film, Hermes' cabin has tent canvas on the windows for privacy and rooms for each of the occupants; Luke's room has a desk lined with computer monitors, Winged Shoes as a gift from his father Hermes, a map leading to the Underworld, a collapsible shield, a cot, and shelves.
Hermes' Cabin is the largest cabin and is packed at all times.

Hermes' Acceptance Policy
Being the god of travelers, Hermes' cabin has an acceptance policy stating that any undetermined camper can stay inside. This means Half-bloods whose immortal parent has not claimed them or whose immortal parent doesn't have a cabin at camp would stay in the Hermes cabin.
After the events of The Last Olympian, most of the minor gods were given cabins at camp. It is assumed that the policy then only covered the unclaimed. All new campers stay in the Hermes cabin until they are claimed by their immortal parent.
- The Hermes Cabin is the only known cabin to have two head counselors, Travis and Connor Stoll. Though in The Lost Hero, Travis goes to the head counselor meeting without Connor. It is still unknown why Connor wasn't present.
- Conversely, in The Hidden Oracle it has been revealed that Travis has gone to college, thus leaving Connor as the sole Head Counselor
