This trail has huge boulders and multiple drops in succession. A lot of the trail is ground out to be narrow between the rocks. It is a challenge riding both up and down it. That said, it is a fun challenge. Very unique experience here in Phoenix to try and no dab as you find your best lines.

      Did the mormon-national loop and both are definitely more chunky than they were before the rains we got this summer. Still fun!

       This is one of the best trails in Phoenix! It's got everything from techy rock gardens to fast flow, alt-lines, drops, and steep climbs. Most people ride this section as an out-and-back or climb up Mormon trail and then link back into National. I wrote a more in-depth article about the National Trail if you want to check it out here! twowheeledwanderer.com/posts/the-national-trail-phoenix-arizona

       Favorite trail in Phoenix/Mesa area so far. Challenging with some tech sections but most of them have several different lines to make it smoother or sketchier. A few quick techy climbs even on the DH that will improve your skills.

       I'm not an AZ native but compared to other black diamonds I've ridden in the valley I'd say this is more of a double black. Definitely lots of double black features and sections. Fun trail, very technical and challenging. I'm okay admitting I did a fair amount of hike a bike.

       This section of national is by far the most popular to ride. I’d say this section of national is a black diamond trail with a few double black features. The trail isnt rated a double black because the double black features have bypasses or are easily walkable.that being said this trail is fairly technical. You need some good skill and effort to get up to
      national and ride down it.

       National Trail is a rocky and rowdy trail located at south mountain. This trial is a local favorite with many features that make it unique. This trail rides over and next to large boulders. My favorite aspect about this trail is how it flows. When riding this trail you are either riding very rocky and bumpy sections or hard packed smooth single track. This combination of smooth and rocky makes for a very fun trail with many challenging features. This trail is famous for a feature called the waterfall. This feature is basically a massive pile of rocks that looks like a waterfall. people all around the country come to the south mountain to ride the waterfall and get down it. The scenery of this trail is unique, you can see the city of phoenix and the sky harbor airport, but you are also surrounded by mountains and boulders, this gives this trail a very nice scenery.

       With the right climbing/trial skills it's a fun cleanable climb. Very much on the steep side though. Recommended for riders who love the climb with tricky features.

      I wish I could've ridden it downhill. We met a lot of mtber's and they were all going the downhill way. Looked super fun. I agree with the other comment- a good amount of black and blue features with 2 or so double black features.
      Beautiful views. Lots of hikers--it's good to yield to hikers, keep the vibe courteous and frieldly
