Jewel of the Amasa Back area, relatively new to the other trails. Fun transitions and some great little rock drops. Hymasa is a bit easier, so if you are unsure of your skill, start there, and then climb back up Hymasa to do Captain Ahab.

       double black rating seems a bit exaggerated. I would consider this a black.

       Double black is probably there for the 5% of the trail with exposure and drops--mostly near the bottom.

       I rode it at the end of a long day, and it seemed harder then it was. I got out there last week, and relative to the other trails and moab in general, definitely more of a single diamond. It is officially changed.

       Trail is now shown as double black on trail signs and that is accurate when compared to surrounding trails.

       This trail paired with hymasa is pretty brutal, physically. People I ride it with who are not in great shape, though skilled technically, don't like it nearly much as people who are in real solid physical shape. Ride at the end of your biking season for maximum enjoyment.

       If this is double black, then Jackson's is as well. Jackson's is harder imo.

       This trail can be difficult due to short punchy climbs and tight corners (no switchbacks though). Much more fun second lap once you know where to shift and keep speed

       Absolutly no way this is double black. This is a recent change made to water down the rating for so many new riders.

       I know, but that is what the sign says on the trail, and that is how the local association wants it marked on the map. But you can vote for it to be a different difficulty

       I think they mark it that way to keep all the travelers here from attempting something way out of their range.

       If you take some of the alt-lines it's definitely a doubleblack. Depends on how you ride it.

       No flow? I agree that *upper* Ahab lacks flow, but lower Ahab has plenty.

       If you think Ahab is a one star trail you need to find a new sport.

       I loved lower ahab - just need the endurance to keep the speed up. I did the Hymasa/Capt Ahab loop. My main complaint is that I didn't leave early enough and in July its bloody hot. Big Grin

       This trail requires a lot of endurance and power to make it flow but it is for sure there. If this trail is above your skill level it will not flow and you will hate it.

      The double black rating is warranted but only for the very end. It gets very technical and very exposed. The majority of the trail is black diamond and is tons of fun. It will push your technical riding for sure.

       Fun trail that would definitely be considered double black in most anyplace other than Moab

       From a mediocre Northwest rider, everyone's comments are correct. It's definitely not a double black. The climb is as bullshit as everyone says. The flow is there, but you have to work for it (what kind of flowy DBs are you all riding, and when can I hit them?). It's a 4.5 star route.

       Great trail. I rode it blind solo and found lots of flow but look before you leap on the bottom section. Mostly a blue/black with a few options to get sketchy and a few challenging consequential spots toward the bottom.

       So many gatekeepers saying it’s not double black. I think it boarders between double black and just black. If you can ride black it’s a good step up. Plenty of aggressive spots that are decent consequence. I think people knock the double black rating more because it’s an amazing trail that feels really well thought out for biking making it seem easier than it is. Absolute must ride if you’re up for it.

       First time riding on red dust and the ride was a spiritual experience for me. Growing up riding PNW in BC I agree this could be a single black but, the parts with exposure could make it a double. I agree with some comments that you need some speed to get the flow.

      heephop (Oct 9, 2021 at 6:16)
       Maybe the most fun trail in Moab. Has an amazing flow if you are skilled enough to carry speed through the whole trail. The climb is really fun if you can keep your speed up in the technical areas and although challenging it’s a great feeling cleaning the uphill techy sections. If you’re an average or advanced intermediate rider you may struggle to find flow and will probably hate the climb but if you’re a more aggressive rider with good bike handling skills the hits keep coming back to back and you can get a great flow on this trail that combined with the drops and techy sections makes for an amazing ride. Definitely my favorite trail n Moab. Anyone who’s complaining about lack of flow or the climb probably just thinks they’re a better rider than they are and are the reason why trails like slickrock are now rated black when they should be an easy blue. My message to those complaining, get better at riding.

       Still the one! Love this whole ride, great way to get started on a trip to Moab. I have to laugh about everyone saying it's not a double black, remember when you had to push your bike up a few of the climbs? Some of us ride that stuff! If you walk ANY of the stuff (up or down) here you're going to have a pretty rough time hitting Gold Bar Rim + Portal.

       One of the best trails in Moab. If you do the Hymasa-Upper Ahab-Lower Ahab loop it can be pretty challenging even for intermediate riders. However, this past trip I rode Hymasa and cut across to Lower Ahab skipping the upper portion. We rode Porcupine Rim the day before and still had 2 more days of riding so I didn't want to over do it on this particular day. There are only a few sketchy sections. The scenery is amazing as you work your way down around whale rock. The trail has plenty of flow mixed with climbing and technical challenges - what more can you ask for from a trail? A must ride if you are in Moab.

       More flowy and rock rolls, drops and less climbs than lower Ahab. Easier than upper Ahab. More consequence. More flow, less jank.
