> With most parks the crowds quickly disappear once you are 2 miles in.

And those crowds just aren't present in the early morning. Nobody gets up early enough to be out at sunrise. I'm not worried about saying this out loud and spoiling it either, because most people just don't like to get up that early.

I've been to gorgeous places all over the US that are absolutely packed by 10am or noon. Those same places are completely empty, and even more beautiful at sunrise. I live near one of the best mountain biking places in the southeast US, and regularly do 20-30 mile rides starting at sunrise, and only occasionally see a runner or another cyclist. There's just nobody out in the early mornings.

Also, when the weather isn't perfect. I love taking a hike when it is chily, rainy, or even cold and snowing.

All it takes is proper gear.
