Senior Sections explore the canoe routes of the Northern Cree, Ojibway, and Innu peoples of northeastern Canada.

Section B travels the traditional river routes of New Brunswick and Quebec, such as the Coulonge and Dumoine Rivers, and is offerred in two, four, or six week enrollments. This is a great way to get a first taste of the immense scale of undeveloped Canadian wilderness available for exploration by canoe.

Section A is the culmination of the Darrow experience as a carefully selected group of highly experienced Darrow veterans pursue a major Canadian expedition in northern Quebec or Labrador during a six week enrollment. Rivers that Section A has traveled in the past include the Rupert River to James Bay, the Mistassini, Mistassibbi, and the Mistassibi Nord-Est in Quebec, and the Atikonak River in Labrador. The members of Section A are pathfinders who open new horizons for the younger campers and staff, and the Section A trip is the wilderness experience of a lifetime.
