Ignacio Dean Mouliaa, 32, of Malaga, set out March 21 on his "Earth Wide Walk" to raise awareness of environmental problems and raise money for charity, The Local.es reported Wednesday.
"This is day six, and everything's going really well," Mouliaa said.
Mouliaa said he initially came up with the idea a couple of years ago.
"It came out of two things: a dream and a need. The dream was my personal dream to walk around the world while the need was to promote love and respect for the environment. Our job is to look after the earth for our children, and the most environmentally friendly mode of transport is walking. Walk around the world is the best way of getting this message across."
Mouliaa said he plans to walk across 40 countries on six continents.
