These were all original to Portland's exposition, such as the Temple of Mirth, a fun house, and the W.H. Barnes Exhibit of Educated Animals. The latter included such acts as Princess Trixie, the Educated Horse and the Famous Diving Elk.
At its opposite end, by the main fairgrounds, the Trail connected with Astor Drive. Here were found the Experimental Gardens as well as Centennial Park. The pathway also joined Gray's Boulevard, which extended through the length of the fair between the main exhibit buildings and Guild's Lake. At night, along with the rest of the fair, the Trail was lined with lights, which made it glow from end to end. The pathway pulsed with energy most days of the week, except for Sunday when all movement came to a halt. Although the fair was open on Sunday, the Trail was closed and all operations of its machinery were stopped. On this day musical, educational, and religious exercises were given special attention in order to respect the beliefs of those in attendance.
