The Rite of Tal'oth is a Vulcan desert survival ritual conducted by young adults who are required to survive for four months in the desert with only a ritual blade being in their possession.

It was considered a more advanced version of the Kahs-wan ritual. (TTN novel: The Red King)

Spock undertook the ritual in his adolescence. (TOS comic: "When Worlds Collide: Spock Confronts the Ultimate Challenge")

Tuvok participated in the Rite and found Starfleet training to be less of a challenge. (VOY episode: "Displaced")
