Yes Saturn's largesr moon Titan (discovered 1655) is larger than Mercury and Jupiter's largest moon, Ganymede(discovered 1610), is too.

Mercury's Equatorial radius: 2439.7 km (0.383 Earths)

RADII OF TEN LARGEST SOLAR SYSTEM MOONS (cf Earth = 1)

Ganymede 0.413 (Jupiter)
Titan 0.404 (Saturn)
Callisto 0.378 (Jupiter)
Io 0.286 (Jupiter)
The Moon 0.273 (Earth)
Europa 0.245 (Jupiter)
Triton 0.2122 (Neptune)
Titania 0.1237 (Uranus)
Rhea 0.1198 (Saturn)
Oberon 0.1194 (Uranus)

So Callisto is almost as big as Mercury and both Ganymede and Titan exceed it in size.

Saturn's Moon "Titan" is about the same size as Mercury. i checked several sources and that is the best answer i could easily find. Merecury has a diameter of 3,031 Miles. The surface of Titan is covered with a thick atmosphere which makes it rather hard to see. What you can see is a mass of swirling distrubed gases which hide the actual surface features of Titan.

Some fairly neat photos have been taken of the other significant moons:
Enceladus
Rhea
Dione
and
Tethys.
Of them all, i think Dione is the coolest to look at because it has these light traces of something going across the surface
of the moon like huge jet trails or something.

Enceladus and Tethys show lots of cratering and scars from collisions with asteroids and meteors over time. There is not a lot of cloud cover to interfere with photographic missions on those two moons.

It was long thought that Titan was the largest satellite in the solar system but recent observations have shown that Titan's atmosphere is so thick that its solid surface is slightly smaller than Ganymede's. Titan is nevertheless larger in diameter than Mercury and larger and more massive than Pluto.
