I see very few recent reviews of this lovely trail. The tunnel under Rt 22 is indeed open and allows road access to Canoe Creek SP. The signage to Flowing Springs Rd access and parking appears to be upgraded as well, as another user noted it may have been missing in the past. This under-utilized trail continues to be a year round favorite of this biker.

What a great section of the Ghost Trail. Wehrum has a large parking lot and is easily found. Only a little over 2 miles from Route 22. No one else was parked there, so there is plenty of room. Trail is very flat and very well maintained. Less than 48 hours since a big rain storm and the trail was dry! Good idea to wear bright colors (orange) since you'll see some hunters this time of year. This was our first cold weather (48 degrees) ride and we learned plenty. Next time gloves and a scarf. Can't wait to come back and explore another part of this trail.

The trail is really smooth and well-maintained. The bathrooms and water stops are in great shape. It’s a great place for an out and back on the bicycle or a pleasant walk for any segment.

Ride side-by-side the whole way. Good hard surface for mountain bikes, just a very few soft sandy spots along fields. Pretty flat (a degree or two) except for a few road crossings.

Can start downtown Shippensburg, or we usually start a mile East at the Shippensburg Township Park to avoid walker congestion. Wide path with no power lines, can ride side-by-side the whole way. Very scenic on the bike, when there are banks on the side they can be typically seen over if on a bike. Quite a bit of tree tunneling to pedal through. There is also quite a bit of unprotected trail, so would not recommend riding on hot summer day with sun directly overhead. Especially true past Newville.

Have done this trail a dozen times over 5 years, it is consistently good with light traffic once you get away from the University. Good old/Amish/Mennonite farm scenery with animals, there is a one mile section with views of the mountain range 10 miles away. Stunning. This is one of the prettier trails we've done in the last 10 year.

Facilities along way. A great old ice cream shop with a non-working soda fountain in Newville. Be sure to go inside, though they also have picnic tables outside.

Recommend early spring through late fall, avoid hot summer when the corn is tallest and the sun directly overhead. Benches and sufficient picnic tables along the way, though nearly all are in direct sun in summer.

It’s a fantastic trail, scenic by the River and we saw wildlife and it’s in superb condition.

At sunset park it’s a nice trail. Once you get to Toftrees a short ride away, it turns into dirt and rocks. Not worth seeking out unless you live in SC.

Though open to bicycles, this trail is very rough with it's washboard surface and large gravel. I even found it difficult to walk on.
We parked at the Gillentown trailhead (approx mile marker 49) and proceeded to bike towards the higher mile marker numbers. Though it was very pretty, the surface was rough. Some points we got off and walked our bikes and even walking was difficult. We only went out a few miles then turned around coming back to the parking area. We proceed to bike the other direction, lower mile marker numbers and towards the Clarence end of the trail which was packed limestone and much smoother though only 3 miles from Gillentown to Clarence.
We wanted to see the Peale Tunnel which was on the bumpy section of the trail and never made it that far. We also wanted to ride across the Viaduct which is farther out. Found out it's been closed since 2013 and no plans in the near future to open it. It's in very poor rotted condition and would take a lot of work to make it passable.
This trail is mainly for ATV's which you need a membership. It's also open to Equestrians and for walking/hiking.

We rode the western section of the trail, most of the time there is constant noise from the nearby highway. The trail is well maintained but the stone surface is rough compared to many of the stone trails we have ridden. Much of the trail was in full sun, which on a cool day in October was okay. Also the rest room (portable toilet) at the train was closed and a sign read, "Closed for spring cleaning".

Good ride for a flat lander from OK with wiener dog in toe. Short but very pleasant!
