The best adventure games like Super Mario 64 are Super Mario Odyssey, Super Mario Galaxy and Banjo-Kazooie. Below are 6, each with the reason it is here — and, at the end, what filtering to adventure costs you.
Filtering to adventure means the place and the story are what you want back, not the challenge. It is the right filter when the thing you remember is where you were rather than what you did.
What you get: A world with a reason to wander it, and writing that survives being read rather than skipped.
What made Super Mario 64 worth playing in the first place is covered on the full list. This page is the adventure part of that answer, and only the adventure part.
The direct descendant, and the moveset is even deeper.
The best-designed 3D Mario, if you can live with less freedom.
Rare's answer, built on the same engine ideas and denser with things to find.
The PlayStation take, gentler and with better worlds than it gets credit for.
Hub-and-levels platforming where every level is a different idea.
Seamless open platforming, no loading between areas.
Mechanical depth. Several of the best adventure games have combat that is deliberately unsatisfying, because they want your attention somewhere else.

No. Super Mario 64 released on the Nintendo 64, but a recommendation is only useful if you can play it, so the picks above span platforms and eras. What they share is the genre and the reason.
Anywhere the story and the place matter more than the skill ceiling — point-and-click, walking sims, narrative thrillers and most open worlds. The label alone tells you very little, which is why each pick here says what it actually is.
They split hard. Open-world adventures run to a hundred hours; the narrative ones are often finishable in an evening, and the short ones are usually the better written.
By hand. Each pick was written for the full Super Mario 64 list first, on what the game actually does, and this page is the part of that list that is adventure — never a genre tag lookup, which is how "best racing games like Super Mario 64" used to be a page on this site.
