Trail Lightning
Definitely the most fun trail at the state park. Super fast and flowy and littered with jumps.

If you disagree with the rating, please submit your own rating on the trail page. It really helps the trail managers if enough people give their opinions. I f a number of people rate it the same as you do they will reconsider.

Fun trail, pretty smooth, but I wish it was one-way. Lots of bikes out on a Sunday.

This trail pushes me to ride harder than other trails because it's more fun fast.

Fun trail. This is built identically to Jeckl n Hyde but just less sustained climbing and newer as of 2019 so roots n rocks havent been exposed by rain tet.
Dont skip it bc someone rated it green. Yes is rideable by beginner but fun flow trail.

Jumps n turns. Watch out for gap jumps w holes after takeoff ramp if u are putsing down.
Not really a black until u go fast. Rideable by most anyone. But pros will enjoy it at intended speeds. Downhill only

This particular trails is the topic and it is marked "downhill only" . I think you are saying that within the entire trails system of Oak Mountain there are also climbs, yes, there are plenty of other trails, most are not marked with a direction. Trails on a big hill are climbs going up and descents going down. IF it is marked "downhill only" then watch for fast downhillers railing a corner, keep your head up just in case, no, not a lot of riders all the time, so possible to go up the down escalator and never see anyone.

Hey AJ -- there is a portion of this trail (a different entry off of boulder ridge) that is downhill only, but thunder as a whole is not direction-specific. Lightning down below it is downhill-only, however! I think what JDC meant to convey is that there are some significant grade reversals on this "downhill" that make it far from a pure downward slope top to bottom.

I enjoyed it! I think I came out on the hottest week on record in Alabama, so I b-lined straight to it from STH and pushed up from the bottom where it meets thunder so I could check out the lines. Some of the landings were a little short, and will probably erode quickly, but such is the nature of steep trails. Overall enjoyed the plop drops & terrain in general. I feel locals could probably use some "in between" features to bridge the gaps in technical requirements. Would love to ride again when it's not so hot!
