The new Hardline trail, built in 2025, is now Sedona's most technical MTB trail.
Hardline is accessed by first riding across Hiline, which is easily one of the most beautiful trails in Sedona. Then, before the classic Hiline descent, Hardline peels off to the right and drops down the flanks of Cathedral Rock, dumping into the Templeton Trail at the junction with Easy Breezy. Hardline measures just under a mile long, but the crux of the trail descends close to 450 vertical feet in half a mile.
Hardline is "a legit double black," according to Romig. To keep unprepared riders off the trail, Romig and his crew of local builders built a squirrel catcher at the top consisting of "two different rollers that drop 80–90 feet of elevation in two different sections. And they're just kind of like a filter to make sure that if you're okay with that, you can continue, because there's much harder stuff ahead, more exposed, a little bit more of a head game."
There are no b-lines or bailouts on Hardline. Once you're into the meat of the trail, you are 100% committed.
