Momiji Valley is a small park laid out as an artificial valley in one corner of Shiba Park, between Tokyo Tower and Zojoji. Its main features are a two-tier waterfall 10 metres high and about 200 maple trees, with the maples at their peak in December. A walking path runs alongside a small stream with benches, and the park is also visited as a spot for photographing Tokyo Tower; one loop takes about 10 minutes. The park is small, so the space for staying a long time is limited.
