My perfect hike would include:

Solitude.
The smell of rain soaked desert (or fresh pine).
A cool breeze.
Spotting interesting flora and fauna.
Flowing water nearby.

I've got a headlamp that is an LED/Halogen combination. The LED is great for map reading, slow hiking at night, or tent activities. A second click on the power switch shifts to halogen and is great for when you need more light. I picked up mine ( Black Diamond Gemini ) at REI and find it much better...
