The biggest canyon on Mars, Valles Marineris, is much larger than the Grand Canyon on Earth. Valles Marineris stretches over 2,500 miles in length, up to 7 miles in depth, and reaches widths of up to 120 miles. In contrast, the Grand Canyon is approximately 277 miles long, 18 miles wide, and has a depth of about 1 mile.
Both are exceptional places to visit but the Grand Canyon takes the Blue Ribbon in this competition. Depending on how and where it is measured, the Snake River has carved Hells Canyon deeper by 2,000 feet, but at 10 miles in length, it is dwarfed by the 277 miles of the Grand Canyon carved by the Colorado River. The Grand Canyon is easily accessible, has a much greater variety and length of trails and better amenities.

It's about 250 highway miles from the 4-Corners to the main settlement of the Grand Canyon (the area with all the hotels and development on the South Rim). The Grand Canyon itself is over 100 miles long, though, so parts of it are closer and parts are farther. The North Rim would be a much longer drive, for instance.
No, Vales Marineris is much bigger than the Grand Canyon.
