In reply to colenn: Hi
Full stottie is right, if youwant an enjoyable climb on the Engelhoerner the weather needs to be good and most of the snow must be gone. This can be the case from middle May till middle september with a bit of luck.
Engelhoerner is a complex and dangerous area, beware especially of the treacherous descents. If the weather is right for you I 'd recommend a) getting booked into the Engelhorn hut the night before (it's pricey but worth it)
and b) a recce the day/evening before to identify your route and waymarkers for the descent.
I can recommend the Kingspitz Nordostwand and Westkante Vorderspitze, both excellent, no harder than F6a. They re both serious alpine outings that take a little planning and I wouldn't go on them in shaky weather.
There are some more escapable multipitch routes of that grade on Rosenlauistock which are also very good.
Stay away from Breitenbodenturm - it looks good from below but is a falling apart mess.
There is an excellent, very detailed Guidebook called "Engelhornfuehrer" readily available locally (Author Kaspar Ochsner) which I think is essential if you want to give it a go, even just for the detailed topos.
As much as I like the "Plaisir" book, on the more alpine craggs it has bitten of more than it can chew. By that I mean the chapters about Engelhoerner and Gelmerhoerner.
They are a little too complex and hazardous for a compressed guide like that. It's still the best by far though to get started in the area.
Good luck, have fun, "Hals- und Beinbruch..!"
