Need to juice up your landscape photography?

Numerous examples of great landscape photography. Guaranteed to have trudging around in the great outdoors with your gear in no time.

In my limited experience, the following tips always seem to contribute to memorable landscape images:
A tripod. A large depth of field (f11 or better) is usually desired to capture maximum sharpness, which often means long exposures of 1/5 sec or more. Even better would be one with a spirit level, to help keep the horizon level.
Avoiding midday sun. There is a wonderful ability for morning or evening light to evoke a mood or creat a more memorable image than say if you took the very same scene in the middle of the day.
Using filters. It may be a polarising filter to bring out the blues of the sky, a neutral density filter to allow the blurring of grass or water, or even a coloured filter to lend a certain scenic atmosphere. Many will say that all this can be done in post-processing, which is true, but personally, I think it's still more fun to do it at the image-capture stage.
A good quality lens. Avoid the temptation to scrimp on lenses. I think most experienced photographers will accept that a lens upgrade makes a bigger difference to image quality than an equivalent camera upgrade. It doesn't matter if it's an ultra-wide angle, or a telephoto zoom. Your style will dictate which is more important. Getting both would be even better. And make sure you use the hood.
Sturdy bag / pack. Often great landscape shots mean getting that angle that no one else has before, and this usually means some trekking, whether through underbrush, across a muddy field, or up a slope. Having sturdy, comfortable carrying gear means you can worry more about composition and lighting than your sore neck, dust or moisture.

And make sure to have fun. I apply the same philosophy to landscape photography as I do to golf - even if you have an off-day, at least I got to get some fresh air and stretch my legs. Enjoy!
