に, で, and へ all feel like "at", "in", "to", or "by" which is why they confuse learners. The key is to ask: is something existing/going somewhere (に/へ), or is an action happening there (で)?

The classic trap: に vs で with location
Both に and で can follow a place but they mean different things:
公園にいます。
I am in the park. (just existing there)
公園で遊んでいます。
I am playing in the park. (action happening there)
Rule: static verbs (いる/ある/住む/生まれる) → に. Action verbs → で.
に vs へ for destinations
Both work for "go to X". Use に when you're thinking of the destination as the endpoint. Use へ when you're thinking of the journey or direction. In daily speech に is more common; へ appears in formal writing and signs (e.g. 東京へようこそ).

Quick test: Can you replace it with "where the action happens"? → で. Is something moving toward or existing at a point? → に. Is it purely direction/movement? → へ or に both work.
