Spelunker’s Frozen Custard & Cavern Burgers pairs hand-formed burgers with real frozen custard and a daily rotating flavor, at the north end of Skyline Drive in Front Royal. It’s a genuine meal stop, not a quick sweets errand, and one of the better-reviewed casual restaurants in Front Royal.

It is open every day, 11am to 10pm. It’s roughly 30–40 minutes from Luray, so it fits best as an anchor for a Front Royal / north-end-of-the-park day rather than a casual add-on.
