Many people come to the Grand Canyon to hike its trails.

But due to natural elements and overuse, many of the trails fell into disrepair – the Grand Canyon needed a hero (or heroes).

“We’ve had as many as 1,500 to 2,000 people going through the park on the trail system down there,” said Ranger Dave Uberuaga.

Enter: volunteer tourism.

It has become one of the fastest growing tourism trends in the past few years.

Each year, volunteers clean up the effects of wildfires, monsoon, and visitors at the Grand Canyon.

The Grand Canyon offers a variety of volunteer opportunities, perfect for retirees with time on their hands or people who just love to travel.
