Outer Limits is an extension of the Alien Trail loop, the two of which combined equal a 16-mile ride. Due to the length of the combined loops and the endurance required for this trail (it's an unrelenting intermediate trail without much variation), it is not recommended for beginners.

Immediately after departing Alien, the trail climbs a little over 200 feet of what would otherwise be a mellow to moderate climb; however, the entire climb is a babyhead rock garden, as is the majority of this trail's first four miles. If you begin this loop fatigued, you'll find a challenging grind ahead. After the initial push, you will descend and climb several times through slower, technical rock gardens with the steepest descents in the entire trail system. Your wrists and shoulders won't let you forget about this trail for days (think pounding, rocky descents). This loop is an exercise in endurance; no sections are particularly technical, but as you fatigue, front wheel placement may become sloppy and the unforgiving bowling ball-sized rocks will ruin your day.

The trail is very narrow, curvy, and not nearly as well worn as Alien, so long sleeves (glasses, obviously) and even leg protection is recommended if you hope to keep your skin intact. The stout junipers that line the trail whack your knuckles and tear at your shoulders and arms throughout the majority of the trail. But that's part of the fun so long as you're prepared!

Just when you start to doubt your skills and endurance, around mile four of the Outer Limits loop (roughly mile 8 total), the trail smooths out and begins a more flowing downhill trend. Then, at mile 6.5 of Outer Limits, you rejoin Alien to complete the circuit.

If you're looking for a fast, flowing 6+ miles of single track, this trail is not for you. If you want a moderately challenging but very rewarding rock garden that will test your climbing and descents, along with a few battle wounds from trees, you've found your place.

Could be a little better marked and some brush cut back in places but really nothing wrong with the trail. Loose rocks, a lot more work than...

Primarily dry but not a fun ride. Somehow you only go uphill and it's all lose river rocks.

Decent amount of snow in the shaded spots, which made climbing and some of the more rocky sections a bit of a challenge. The soil started to...

The lack of recent rain has made the sandy parts sandier.
