Where to begin... the aim was Red Arete but... parked at wrong carpark, approach instructions now lead us to the wrong crag, I didn't look at the topo just the route description, didn't want to walk backwards to find the route, felt like we were on the wrong climb when the first pitch has no rap chains half way (it does but I thought my pitch was closer to 30m than 60m) and I stopped there and set up an anchor (uncomfortable) G then followed and went to the top of this climb and I followed, technically wasn't on sight since I stopped half way but it was easy and I didn't get any beta off G. Then after G finished I saw bolts above and we assumed we kept going, Nicked extension is a 20 with 2 small roofs. Led to the first roof fine after seeing bolts and rap chains going everywhere. Started getting over it (seemed much harder than anything I'd assumed I was on) and midway through the move my left foot popped, shin smashed the lip of the roof and fell very unexpectedly, got quite scared and after much umming and ahhing decided to downclimb removing bolts on the way to a random rap point, G then climbed up to me and we bailed from here 5m or so under the roof, rapped off and walk back to the van before working out what we had been on the whole time. At least I didn't fall off a grade 15 climb 💁♂️
