The Orange Trail is a long trail, following the complete length of the park. It starts not at a parking lot, but rather on Centerline road on the other side of Hunters Creek from the parking lot. You can reach the start with a very short down and up on Centerline Road.
The trail starts with a nice gorge-edge bench cut with nice views of Hunters Creek far below. It then enters a hemlock section before crossing the first of many tributaries. Your climb from this crossing is barely over before it turns back through the hemlocks for the next tributary crossing, this one more rocks than water.
The trail continues north along the top of the Hunters Creek ravine until you reach intersection 31 with the West Yellow
segment. Stay straight on the orange past some very rooty sections until you enter a piney area. You can drop down to the creek here at intersection 34 if you want, but stay on the slope and continue up the bench cut to follow the creek further downstream. You'll pass intersection 35 with the other end of the west yellow segment.
Soon you find yourself on a ravine edge high above (and with a sheer drop down to) Hunters Creek in a Hemlock grove. Stop and enjoy the view! A very deep tributary requires you to follow this upstream to a crossing and a climb back up the other side to intersection 36 with the East Green
Stay left, cross the rocky ford, and continue along until you again find yourself at the top of a very tall cliff above Hunters Creek. Great views!
The trail veers away from the gorge edge and makes a sharp right turn up the hill at intersection 38 (a left will bring you straight down to the creek). After a very short pop uphill, you go left at intersection 39 and twist and turn along a very flowy section first along a pipeline, then a tributary until you climb to intersection 40. At 40, you cross the tributary and go straight on a wide section until intersection 41, where you hang a right onto a board walk section that gets you through a wet area. At intersection 42, the trail follows a small creek to where the trail crosses the pipeline.
On the other side of the pipeline, you start your descent to the lower parking lot. This section goes through some wet areas, made possible by wooden boardwalks. At intersection 44, you start to go downhill fast, with a sharp right at the bottom. Hopefully you downshifted first as you have a series of gullies to pass through before ending at the lower lot.
