Reviews? By what kind of trustful sources? Instagram? 😱
Why not starting with hike descriptions, e.g. on the Zermatt tourism site?
Check out no. 36 (one way/half of it, possible with sneakers when dry) or no. 26 (either way, hiking boots required).
Discuss those options with the Zermatt tourist office when you’re there, who will advise you on the current weather and track conditions and can tell you how much you can save on the cable car tickets when hiking some stretches.
