This is one of Moab's classic 'must do' trails for expert riders. This trail is really like two different trails, the top half and the bottom half. The trail starts out on trail that has a lot of exposure. The first half is really not all that difficult, and goes up and down with some difficult climbing spots in addition to off camber rock edges. The trail starts right out with a filter feature, which is a difficult tight left turn down loose rock steps. If you walk this, expect to walk most of the bottom half.

There are several places to dismount that are very dangerous and close to the cliff edge for the first half. Once you get around the bend into the canyon, there is a short drop to an open viewpoint and a nice view point. This is where you start the lower half.

The lower half is very technical, with some sharp turns that include 2 to 3 foot drops in succession. Some sections include very steep rocky sections between massive boulders. As you get closer to the bottom, you pick up speed out in the open, but quickly find yourself into drops into loose rock and more rock gardens. Very technical, easy to wheel trap.

As technical a trail as this is, it is a lot of fun to test yourself, your bike suspension, and your ability to lean back and not go OTB.

Access Info

Not the easiest to get to. Some people will climb up the steep slickrock Poison Spider Jeep trail, but this is a horrible climb on a bike. The preferred route is to shuttle to the top of Gemini Bridges.

      Its a bit overrated, not even close to proline. Two exposed places other than that maybe a doubleblack. If you are an intermediate rider you can easily ride it. Bottom part its a bit technical and thats what i like so for me its probably an easier doubleblack.

      Proline rating is a bit silly, just walk (the well signed) section close to the cliff. The technical difficulty comes on the lower half. Nothing crazy but probably the most continuous technical difficulty in Moab.
      Great trail, easy double black when ratings in other areas are taken into account.

      Finally got to ride this after all the hype. King of the Double Black Diamonds! So much rough, tough tech and whacky challenges. Felt like it was a GREAT payoff too, just kept going. The Proline rating doesn't seem to fit, but my guess is it's due to the two sections where walking is a must and to keep the unskilled and unprepared from attempting. Everything else is NASTY, but no big gaps or giant drops like I would expect on a triple black diamond. If I did this again I would find a way to get shuttled by a 4x4 up to Gold Bar Rim Singletrack and start there. It is friggin' TEDIOUS to start at Getaway (MAG7) and eventually get to Gold Bar Rim.

      The exposure doesn’t seem dangerous; signs ask you to walk, and it’s fine. The riding itself is no more difficult than the other double blacks in the area, aside from more tricky switchback roll-downs, and you can walk it all of you need to. The views are pretty cool. Overall, the danger comes in not having enough water, or starting to late and getting stuck in the dark (it took us 6.5hrs starting from Bullrun).

      Phenomenal trail that seems to get harder and better the further you go. Bring more water than you think you’ll need.

      Great Ride so far in the area. I rode twice in the last 5 days, and super stocked with MAG 7 as a wordl class big traverse, tech and phisically demand with extraordinary views.
      I rode last saturday but was too many Jerry’s on Portal (about 20 to 30) of them hiking their bikes, I mean not hiking on the exposed sections but all the way down, they’re seems riders with little skill to ride a black trail even. Like family’s and guys trying to bring their girlfriends (for a frustrate experience).
      Portal It’s a true double black and people should not attempt if they are not able to ride and control their bikes in a step and technical terrain, its not only about the exposed section but the all run is challenge and awesome ( if you like it).
      To intermediate and fresh advanced riders I would suggest to hike the trail as you gonna have a great time and wont’t need to carry extra 15 to 20kg for nothing, expecially at climbing Gold Rim and Golden Spike. If you want to know if this trail is for you, first ride Jackon and Rockstarter if you clean it and had fun the reach to Portal in the next oportunity.
      Build up your skill slowly then reach the thrill’s with confidence and you gonna have epic fun Wink

      I am terrified of heights but had no problem attempting to do this trail. There was about 4 sections on the highly exposed areas that I walked. I was able to ride most of it until I got down to the very technical switch backs. I really enjoyed making my way down Portal and challenging myself to this level. My goal is to be able to ride everything on this incredible section of trail.

      Awesome trail! People mentioned the walking part/cliffs to be scary and overwhelming, but it was just fine (as long as you walk it).
      Beautiful views as well, fun technical trail.
