The 'Temple of the Body' (as is the name given to actual runecrafting area) is a pink, organic-looking area, reflecting the "body" element of the rune. It's also shaped like a heart and the music played there is called Heart and Mind. The roots are coloured purple so they resemble blood vessels. With the introduction of The Great Orb Project minigame, the body altar received a graphical makeover and now roots which resemble blood vessels, are pulsating. The closet bank to the alter is located in Edgeville.
The quickest way to get there is through the Combat bracelet's Monastery teleport, or with the Skull sceptre's teleport to Barbarian Village. The latter can only be used several times before it breaks, however.
Unlike many altars, the entry point is not close to the portal though it is also quite a small area with no places to get lost.
