The present teachings provide a canopy that can be used in the area around a campfire for shelter during adverse weather conditions. The canopy includes a frame, a cover having a centrally located opening support by the frame, and a set of legs supporting the frame with the cover in an elevated position. The frame is constructed with a set of trusses which interconnect a lower support frame and an upper support frame. The trusses and support members are assembled such that the central opening remains unobstructed.
