Mars has the tallest known mountain in the solar system, Olympus Mons, which is nearly 22 km tall. Mauna Kea, the largest mountain on earth (measured from base to peak, not from sea-level) is only 10 km by comparison. Everest, the tallest mountain on Earth, only clocks in at a measly 4 km.
Mars also has one of the deepest known valleys, Valles Marinaris, which can reach depths of 7 km in some places. However, Earth takes the lead with the Romanche Trench, a section of the Atlantic Ocean that drops to a crushing 7.8 km deep.
Of course, very little is known about the outer planets, and given the sheer scale of Jupiter and Saturn, we could make some assumptions about what lies beneath the thick gas layers.

Venus is considered to be the hottest planet in the solar system. Venus is referred to as Earths twin due to the canyons, mountains, valleys, and volcanic activity.
The Himalayas, the planet's highest mountains.
Presently the largest canyon system discovered so far is on Mars and is called Valles Marineris, it extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep
There are many planets that have volcanoes and canyons. The Earth is a wonderful example of a planet with both.
