If you were to ask me (and even if you weren't,) I'd tell this is an awesome ride and if you're in Moab, you should most definitely ride it. Very fun.

This "trail" is mostly destroyed jeep trail... maybe fun for some people, but way overrated in my opinion. The views are awesome of course, but one expects that in Moab. The fact that no emtbs allowed is ridiculous... Moab need to get with the times on that issue. The singletrack does have some fun sections, but the rest of the trail was like riding a jackhammer.

I’d say double track is rad if you like rad gnarly downhills that really test your physical ability. Single track is obviously sick too though.

“Flow” trails are fine for areas with very little acreage to jam in an efficient trail network, but as much as they are fun, they are also generally scripted, planned, and frankly rather sterile. A lot of the new trails in Moab are like this. Fun trails, but essentially all pretty much the same. At its inception, Mountain Biking was about covering large stretches of mixed terrain with resilience, fortitude, and a spirit of adventure. Technical skills were just as, if not more important, than pumping and flow my bro. There were no soulless trail cutting machines and fastidiously groomed berms. The rocks were actually considered a feature and not a bug. Trails had character. So it is with the iconic Porcupine Rim. Love it while it lasts. The lower section was once much more raw, challenging, and gnarly before the masses complained it into submission. Porcupine is a grand cathedral of the sport and should be approached with reverence. If not awe.

Any changes to Porcupine Rim are due to mother nature - the constant sun / wind / rain / snow / etc - not workers making changes. That trail is insanely difficult to get to with tools and so it only receives minimal work. It is also within a WSA which restricts what can be done.
We are lucky to have several MTB Hall of Famers living in Moab and they say the trail is just as challenging as it was back in the day. Remember, though, that bikes have gotten a LOT better, which makes everything seem that much easier.

agree with most commenters here. trail is split into double track section and singletrack section. first half of double track is just a road with lots of rocks and short technical climbs. second half gets more technical with drops and ledges, lots of fun but lots of opportunities to get caught on square rock edges. singletrack portion is awesome and worth going through the double track imo. relatively flowy with cool technical sections (drops, off camber, exposure) and great views. area near the river is REALLY technical on the ups and downs but easily scoped and walked, props if you can clean this.

Moabs biggest disappointment. The last 5% of the trail is super fun and there are awesome views along the way, but most of the trail is just a road full of janky chunder.

Can’t believe I did this ride starting in 102° weather. If your not an experienced rider, do not, by any means, ride this trail. Full face helmet recommended due to jagged rocks and easy over-handlebars experiences. Luckily I did not fly over my handlebars. I could see it happening quite easily as two in my group happened to do this. Bring LOTS of water as well as electrolytes ESPECIALLY if you are doing it in the summer. Some parts of the trail are virtually unrideable (near the end) so expect to dismount (and don’t feel bad about it). Be careful out there, it’s a rough trail that shouldn’t be done without full dedication. Have a good ride.

Description is perfect - epic views, with good flow and some spicy sections. If you're a rook like me, keep your speed up and roll it baby. Retry the stuff you can't do - bc you can.

I am 52 and have been mountain biking for 20 years but I am not a big drop off guy and I am a little more cautious these days due to my age. My bike today was my 2013 Rocky Mtn. Element 930 which is a full suspension cross country bike without a lot of travel. Having said all of that I think Porcupine is a very fun trail and I am glad I rode it. When it looked too sketchy I just walked it on through. We shuttled up as high as we could and did 16 miles on the trail and 4 more to get back to town. It is a very fun and technical trail.

People that don’t like the double track either have shitty bikes, or don’t like rowdy downhill riding.

My favorite trail of all time. It’s only fun if you can get comfortable launching off the jumps. To me it’s the right level of technicality. While I like Capt Ahab for its views etc. it’s a little nerve racking to ride and the downhill isn’t very fast. PPR is fast and not super scary so in my mind it sits right there as the perfect level of fun. Great downhill, really fun jumps and the right amount of technical features to feel like you did some work.

Trail The Snotch
The line down the cliff face is best described as a pro line. Maximum fall hazard, lack of runout, and generally Sandy/ loose conditions as opposed to clean sandstone. It’s difficult to get a bike down solo.

Fun ride. Not a typical downhill trail. I’m from PACNW and have been spoiled riding flowy dh trails. This trail had some sections that flow. Lots of small drops off rock ledges. Some technical sections which will have you on edge. Literally. I brought my enduro bike which did very great for this trails. I ended up getting dropped off at the first trail head off the main road and then had to climb a brutal 3 miles up hill. Which normally wouldn’t be a problem but being acclimated at sea level and then trying to climb at 5k elevation was tough for the lungs but well worth it.

Nice steep and rocky trail. 2 tight steep switchbacks, both are intimidating but not too difficult for a skilled rider

Double track part is fun to bomb but will murder your hands. Last section of trail should be a double black.

This is the best part of the Whole Enchilada, especially as you get further down toward the river. As for the doubletrack, it is kind of meh IF you follow the main lines, but once you figure out that there are tons of alt lines - including drops and kickers - to the sides of the doubletrack it becomes immensely more fun.

Epic view, many technical rocky section, when “flowy” it’s deep sand. I’d recommend this trail, though bring a gallon or two in the summer heat.

This is a very good trail for ADVANCED riders. Do not expect ‘flow’ riding of any sort. The 900’ vert climb to the rim is technical with multiple rock steps. The long descent takes you past countless 1-2’ rock step downs - FUN! Not for the feint of heart. Intermediate riders should look elsewhere - not the place to snap a collar bone. It took me riding solo a total 2:30 fromlower trailhead to hit the river at bottom, incl 20 mins of break time. I would do this again in a heartbeat, hopefully with snow gone so we can devourthe whole enchilada!

Bottom 2 miles of this trail is probably the coolest trail Ive ever ridden. One or two darn near vertical rock garden sections that I hiked(and would rank as double black) but virtually all of the decent was do-able for me with no dabs. EPIC VIEWS

Upper portions are great for views, middle double track is mostly just to get between A and B but the last 2 miles of trail, that's where it"s at. Some of the best built trail you can find anywhere with amazing views and technical moves.

Great ride - one of my favorite trails in Moab! Get a shuttle up and just enjoy the ride down! Love the technical sections and the views are incredible. Highly recommend this trail to any confident rider, and those from out of town should definitely do it (if they're good riders and not afraid of exposure or semi-sketchy technical descents).

Great views and the last section is nice, but I will take the road to Sand Flats next time. Even on a big squishy 150mm 29er, this trail was extremely rough and downright painful to ride. I landed on my wrist earlier in the day and the constant jarring put me in a lot of pain.

Porcupine Rim is a great trail. It is a very fast, kick-ass, rockin' downhill trail that will rattle your teeth. If you are looking for a lot of uphill portions, this trail is not for you. I started at the LPS and had essentially no climbs. There are super fun technical spots and killer views. Have fun and shred hard!

Even though parts of the porcupine rim are double track, I found it very fun to rip down at high speed on a beefier full suspension bike. Then the singletrack portion along the canyon edge is super fun, with some nice optional drops and exposure. Nice thing about the trail is riders of all levels can go, advanced riders will just go faster to make it more technical.
