The word type that would best complete the sentence is an adjective.

An adjective is a describing word and modifies a noun. In this case, the adjective is modifying the word "boulders." An example sentence would be, "But soon, we were scrambling over gigantic boulders and scaling walls of stone." However, any adjective that accurately describes the boulders could be used.
