There's really not all that much I can say about this series. The art style is beautiful and captures the essence of the locations well. If you know nothing about mountain climbing, it's even a little informative, and "peaked" (bad pun, I know!) my interest in trying it myself some time.
There's no action or drama here, just a cute story about a girl gaining confidence and making new friends. The characters come off as a little generic, but they fit in to the story well enough. There is a bit of the "moe" aesthetic here, but this isn't one of those otaku-pandering shows.
The only thing I didn't like about this series was the sound. The music was bland and forgettable, and the voice acting was silly, though not atypical for the slice of life genre.
While not a masterpiece, Yama no Susume does enough with the less than 45 minutes total to make it worth the time spent watching.
