12-Days in Tirol

If you don't already have this website bookmarked I highly recommend it. I have used it a lot.

If you are considering hiking in the Dolomites check out Gillian Price's guidebooks for the area.

Just a few of my favorites...
Not far from Reutte is the Hinterhornbachtal. Nice walk from Hinterhornbach to the Petersberg-Alm. You might just drive and explore the Lech River valley. We are staying in Gramais for a week this year.
Ehrwald take the Ehrwalder Almbahn up and just hike. An easy enjoyable hike is across the golf course from Ehrwald to Lermoos. Clasic views of the Zugspitz and Sonnenspitz. The Romans built a road thru here too.
Zillertal nahe...
Check out the Achensee.
Take the Gerlossteinbahn up and explore. Up to the Gerlosstein if you are able.
Schlegeis Stausee and hike around.
Of course the Hintertux area.
You are not far from the Alpbachtal if you are inclined.
From Reutte drive the Lech Valley 198 to the Bschlaber Landesstraße L246 to Imst, then secondary roads along the Inn River thru Innsbruck to the Zillertal. You cold stop in Hochoetz and take the Acherkogelbahn up. I just like to sit myself down at the Kühtaile Alm, drink a beer or two and enjoy the view.
Just so many places. Rent a convertible if possible. Skip the Autobahns, too many tunnels, noise barriers and the toll.
If you like Honey get some from a local Imker. Mountain Wiesen Honig is the best. Eat a Gröstl and try the Kaspressknödel soup.

The Krimml Falls would be a nice trip while in the Zillertal.
