Signal Mountain – another Alabama Cat 2 climb



Well, today’s mountain bike ride definitely fit the bill for a “cycling adventure”. Highlights included riding in and behind a thunderstorm, riding through a pilgrimage of devout Catholics, stumbling upon a small forest fire, discovering another Strava Cat 2 climb for Alabama, lots of mud, lots of flying ants, and lots of yellow jackets. Here are annotated topocreator maps of my route.

We had some thunderstorms roll through Birmingham this morning, so it was lots of rain on the long ride out to Double Oak and eventually over to Signal Mountain. Most of the thunder/lightning activity stayed just to the east of my location, but it was still disconcerting to be on the edge of a thunderstorm while climbing over the highest ridges in the area. Apparently, lightning from the storm had struck the top of Signal Mountain as I would later discover a small forest fire near the top.

Before climbing Signal Mountain, I had to first climb up and over the Double Oak ridges taking me down into Bear Creek Valley. As I rode north on Co Rd 43 through Bear Creek, I noticed hundreds of cars parked alongside the road. This was really unusual, but it got even stranger as I started reading the license plates which were from all over the country. I eventually made it through the cars to this field and found out by asking someone walking back that some devout catholics believe Mary appears in this field every year near the Fourth of July.

Continuing on Co Rd 43, I eventually made it to this barn which used to have a cool concrete statue of cyclists resting on the ground with their bikes propped up behind them, and turned onto the street/driveway (Moss Rock Trail) that leads straight down to Bear Creek itself and the low point for the start of the Cat 2 climb up Signal Mountain. I turned around at the bridge and began the climb by heading back out to Co Rd 43 and turning left to go back all the way through the pilgrimage area until I reached Season Rd, which is the start of the steep part of the climb.

I’m pretty sure this will be the only time I ever do the climb. It is a good climb through a beautiful area, but the majority of it is on private hunting grounds (hence the name “Season Rd”). I reckoned that on a rainy Monday morning in the middle of summer everything should be deserted, which it was. But this is property that should generally be avoided. At the top of the climb is a single radio tower, which is ironic given that the name of the mountain is Signal Mountain.

The climb starts out steady and steep for the first mile before leveling out when you cross over from the back side of the ridge to the front side of the ridge. The view along the front side of the ridge is absolutely amazing – overlooking the valley over 1000 ft below and the adjacent ridge of Double Oak at nearly 1000 ft above the valley floor as well. After about a half mile, the climb bends around the side of the mountain again and really kicks up in elevation. It was just past this bend where I saw the forest fire. Also, I had to run the last bit because I got off-balance in the wrong gear, and it was too steep to remount – but theoretically the entire climb is rideable without stopping.

After I made it down the mountain, I rode back to the pilgrimage area and reported the fire to a Shelby County police officer who was helping with crowd control. He thanked me and called it in on his radio. Then it was time for me to head back up and over Double Oak ridge … the mountain was swarming with yellow jackets and flying ants. Because of the earlier rain, I had to run several sections and with every footfall there would be a yellow jacket rooting around in the rocks and mud. I was super careful, but it wasn’t until I was actually riding on a slight downhill at about 15mph when a yellow jacket, bee, or wasp came from in front of me and collided directly with my head. The sting was immediate – I couldn’t tell a difference between the “thud” of the bee hitting me and its sting. One day later as I finish off this post, the entire righthand side of my face is swollen along with both sides of my neck.

    Found this page while looking for info on Signal Mountain. Your photos show a concrete footing in the ground. This was probably from the old signal mountain Fire Tower. I had the opportunity to visit quite a few times in 1974. At the time, you could drive all the way up. The views from the tower, as well as the north facing rock cliffs were fantastic. Unfortunately the tower was removed at some point, as were many others, such as the one on Shades Mountain in Bluff Park. Wish I could go up there again. Thanks! Gene.

    Hi Brian.
    I live on signal mountain. I enjoyed reading about your ride here. You must be in great condition to make that climb. I used to ride it when I was younger with a rifle on my handle bars. I have had some close calls with rattlesnakes up there in summer and a man was stung to death by yellow jackets a few years ago. The area is called the penitentiary, named for the mountain that intersects signal Mt. and forms a bowl that is untouched by logging. The timber is like nothing else with a whole mile of old growth magnolias and a cascading mountain stream. It’s a maze of trails so it’s not unusual for people to stumble up to my house, lost and hungry. Glad you’re ok. Pete

      I know this comment was from 5 years ago but I’m one that knows these mountains like the back of my hand which means I’ve been everywhere and there are no houses up there . All that property around signal mountain is Stamps, there’s a 15 ac lake there but no house. But just thought I’d let you know.

    I stumbled across this post while searching for ways to cross over from Dunnavant Valley Road to Bear Creek Road without having to die on 280 or ride all the way to Vandiver.

    I was curious about the concrete block at the high point of Signal Mountain also so I did some research. I think Gene Thompson was spot on with saying it’s an the Fire Tower footing. The footing is mentioned in the National Geodetic Survey Datasheet for the Signal Mountain GPS station.

      Interesting to note that this property or perhaps adjacent property has recently been for sale.


      Would be great if it was open for visitors
