I have been fortunate to sail on almost all of the five star cruise lines sailing today and have sailed most itineraries. While I would choose an ocean liner for any ocean crossing, for everything else, I look for small.

What to pack?

Although my companions and I are far from being swarthy, tattooed sailors full of song and stories, we are in search of the same adventure.

Antarctica is a landscape of superlatives: stunningly beautiful in a very big way.

An impromptu trip to the Sea of Cortez finds wildlife galore.

The same week news broke that Facebook would acquire Instagram, two travelers used the app to shoot their Baja California expedition, capturing a $1 billion memory of a gorgeous wilderness.

With few natural predators, the wildlife here has never had reason to fear visitors, so they go about their normal routines in the presence of humans.

This week our photos come from Galápagos, the Amazon, Antarctica, New Zealand, Costa Rica and Baja California.

In preparation to travel to Africa and start our 7,000 mile walk, I have read and watched many stories of people who have done long term treks, domestically and abroad.

When I tell people I'm about to spend a year hiking trails from New York to San Francisco with my two dogs they shake my hand, wish me luck and congratulate me for living out my dream. But brows furrow and jaws clench when they realize I'm bringing a smart phone.

Eric Larsen, 40, is the first person to have reached the South Pole, the North Pole and the summit of Mount Everest within the span of one year. The goal is to get people to care -- and do something -- about climate change, the effects of which Larsen saw first hand on his journeys.

Although thousands of gringos attend the theatrical representation of Inti Raymi near Cusco, Peru, each year, this is different. This is the real deal: a venerable religious ceremony complete with animal sacrifices.

This is part 4 in a 4 part series. Limbo Leaving the Zagros, the terrain hung in a sort of limbo.  In the late evenings as I searched for a suitab...

Soon the plateau began to change. No longer rolling hills and rocky terrain, I now walked towards daunting peaks. I had begun to enter the Zagros Mountains.

10 kilometers outside of Tehran city limits, the landscape changes abruptly from mountains to low rolling hills. I climbed the red dirt slopes, sinking at times up to my knees in the soft, powdery sand.

I spend the majority of my time on structured, goal-oriented expeditions. So, for my holiday I am avoiding structure at all costs and following my gut and the wind as much as my structure-starved brain can handle.

I pedaled away from all that I was familiar with in England. I rode right across Europe and into the Middle East.

Today, I'm gonna have to walk in the extreme heat of the day to get some time back from this tire repair shop. But I'm doing ok. I've still got enough water and supplies to get me through.
