Imaculata
Hero
Combat, traps and treasures are not the only meaningful content in D&D. Meaningful content can be lots of things. The players could encounter a shrine dedicated to a goddess of travel, during their long slog through the mountains. The players can make a meaningful choice here if they want to leave a tribute at the shrine, or perhaps light a candle, to have good luck during their journey. They'll have no clue whether it actually makes a difference, but that is entirely up to the DM (if I'm the DM, it definitely makes a difference). These little encounters are an excellent opportunity for you as a storyteller to convey a bit of lore, and bring your world to life.
