Apollo 8 was the first manned mission to leave Earth orbit and the first to travel to another celestial body (the Moon) but not first biological mission with non-human creatures from Earth. A few months before Apollo 8's flight to the Moon in 1968 a Soviet spacecraft, Zond 5, flew around the Moon and back. On board Zond 5 were assorted living things, including turtles. The first large creatures from Earth to travel to another world were reptilians!
The Apollo 8 crew also were the first humans to set eyes on the far side of the moon but not the first to photograph it. Nearly a decade earlier in 1959 the unmanned Soviet spacecraft Luna 3 was the first to successfully take and send back pictures of the Moon's far side. As Apollo 8 re-emerged from the Moon's far side and voice contact with Earth was regained Commander Jim Lovell announced "Please be informed there is a Santa Claus" to which NASA replied "That's affirmative, you are the best ones to know" so Santa may actually have been the first human to set eyes on the Moon's far side!
Of the over 500 individuals that have flown in space to-date (many of them more than once), only two dozen individuals have ever left Earth orbit and travelled to another celestial body. The three member crew aboard Apollo 8 were the first to truly deserve the title Astronaut as they boldly travelled to where no human has ever gone before. As for all the other 500 "Astronauts", they have really only flown a little faster and a little higher than us who have flown in airplanes that also fly above most of Earth's atmosphere...

Apollo 8 first WENT to the moon, but didn't land. Apollo 11 was the first to land on the moon in July 1969.
It was another test flight ... you test by stages.
I assume you mean after his spaceflights, in which case the answer is the Pacific Ocean, both on his Gemini 8 flight and Apollo 11.
