So Ptarmigan off Ben Lomond.
Rode it with my mate Marky Mark this weekend and it is a bit of a belter. January is perhaps not the ideal time for such things but we got lucky with the weather.
It's something of a full on tech fest. There's no point at which you can let go of the brakes and just flow. Tight, rutted switchbacks, rocky stone pitching and exposed bedrock make for a lot of slow speed fun. The very top section is a scrambly carry down but then things become a lot more interesting. We had high winds and a bit of ice / wet slippy rock to contend with at the top so some of the stuff that we would normally ride got the "let's leave it for the Spring" to come back on a dry and still day treatment. No point in being a hero as an off had the potential to be really consequential. Seeing one of the Sea Kings from HMS Gannet below us encouraged the sensible hat to be worn.
As we descended, the trail just got better and better and didn't let up until we hit the trail at the shore.
Would I do it again? Absolutely and we're already planning a return trip. Is it better than the main tourist path? Hard to say. If you like tech, it's a peach but the tech is at the expense of high speed flow so you pay your money and take your choice.
Another one to the add to the growing list.
