If you're visiting Schafberg, come prepared adn don't be surprised if it's significantly colder up there than it is down below in St. Wolfgang. Come prepared with appropriate clothing.
Photo Equipment: You'll also want to be prepared with your best camera gear. You should definitely bring a telephoto lens to capture the views of the lakes surrounding you.
Luggage and bags:
Forget these unless you plan to stay at the Hotel Schafbergsptize!
Clothing/Shoes/Weather Gear: When visiting Schafberg, be sure to bring some clothes intended to keep you warm. Temperatures can drop dramatically as you get to the top of the mountain so be prepared. A warm rainjacket would be ideal. Just look at how cold my wife, her sister, and her mom were. An this was during the great European heat wave of 2003!
Photo Equipment: A camera is one item you can not forget to bring. I did not bring the warm jacket, and suffered accordingly. But I remembered my camera and that's what counts!
