I can't help you with specific subjects to shoot, but I can definitely recommend that you bring a tripod of some sort. If you're hiking, I've had good luck w/ a Trekpod - this isn't as stable as a full-sized tripod, but it's great to have a device that does double-duty as a hiking stick, and it's invaluable when shooting landscapes.

I brought my Trekpod on a 10-day canoe trip earlier this summer, and not only did it help immensely with pictures, it also saved my butt a few times on portages when I was using it as a hiking stick.
