The Rideau Trail Association is a non-profit organization and a founding member of Hike Ontario. Its purpose is to preserve and maintain a hiking trail from Kingston to Ottawa. Its registered trademark is a red-orange isosceles triangle; these triangles are used to mark the main trail linking Kingston and Ottawa (to distinguish the two directions, Kingston-bound trail markers carry yellow tips). In addition to the main trail, there are a number of side trails which are marked by blue triangles. The total length of cleared and marked trails is 387 km.
