The Castrum 

The guide is incorrect. The route shown as 'The Castrum' is actually Duchess (5.6-5.7? mixed pockets and a off again on again flaring crack). Castrum is the thin finger crack/face just to the right of #4. If you look carefully, you can see the chalk in the crack on the upper section.

Fun thin route, but definitely hard to protect and thin. Don't forget the aliens!

I've led this route twice in the last year, and I disagree with the rating. I'd give it at least 10b instead of an a. It's a sweet, little route that requires a bit more attention to pro placement than usual. It should also be given a star--maybe two.

A nice climb...all 20' of it! This climb offers a few good moves but is over far too quickly to stick in your long term memory.

Yeah this is a short route, but I like to climb it at least once a season. I feel that the 10a rating is on.

I done this route three times, and I agree it's short, but it is fun.

The pro is actually fine if you have green and yellow aliens and are willing to place nuts.

Fun route!

short and sweet. 10b is fair.

This route actually protects really well with stoppers and TCUs or the equivalent. Given that, it'd be a shame to toprope it, which seems to be the norm for many these days.

I think there is 1 hard move on this line more difficult than 10a.

Short but very fun combination of smearing, crimping, liebacking and jamming. All in 20 feet or so =)

Slick in the heat/sun, but climbed alright. Used the Manaco bolts since we didn't mind the swing.
