We had fun doing the Four T Trail in Portland. We called it the 5 T because we ate at the food trucks for lunch. We took the train to the Zoo. We hiked the trail to the Tram. Took the Tram down to the Trolley. Then took the trolley back to where we parked, near the food trucks.
Hike was mostly in the woods which was good because it was a HOT day. We started early to avoid the heat & did the hike near the beginning. We did the forest trail - around 4 miles. Trail was fairly well marked but I'd recommend having a copy of the trail with you.
