Jonathan Trappe was strapped in a seat below a bright cluster of balloons when he lifted off early Friday from Kent, in southeast England.
After sailing above the water for several hours, Trappe lowered himself into a French field by cutting away some of his colorful collection.
Trappe told Sky News that the crossing fulfilled a lifelong dream and that it was an "exceptional" experience.
He said it was the first time anyone had crossed a significant body of water using nothing but standard helium balloons and wind currents.
The crossing is reminiscent of the animated film, "Up." In the movie, an elderly man attached hundreds of colored balloons to his house to fly away for an adventure - though in his case he traveled to South America.
