Into the Dark, Out to the Dam: An Underground Cave & Mountain Picnic
From shadowed caverns to sunlit damside picnics — a small-group spelunk-and-chill adventure
The cave opens like an exhale. You step from hot, sunlit pines into a cool, mineral-scented throat of rock where drips count out time and your breath fogs for a second before the dark swallows it. Headlamp cones cut tidy windows into the black and reveal banded walls that hold the town’s geology like pages in a ledger. When you finally climb back into the light, the world has a different scale: the dam sits broad and serene, its flat surface a mirror of the Selkirk foothills, and the picnic blanket you spread beside it seems both indulgent and earned.
Trail Wisdom
Bring a reliable headlamp
Battery-powered headlamps keep hands free for scrambling and improve safety in tight or wet cave sections.
Wear grippy, closed-toe shoes
Sturdy trail runners or light hiking boots with good tread handle wet rock and muddy approaches better than sandals.
Hydrate and pace yourself
Caves are physically engaging; start well-hydrated and carry at least one liter of water per person for the 3–4 hour trip.
Pack a quick-dry towel and change of clothes
If you plan to swim at the dam, a towel and an extra layer will make the return trip comfortable.

Conservation Note
The region relies on small operators and a culture of responsible recreation; pack out trash, avoid disturbing cave formations, and follow guide instructions to protect delicate subterranean habitats.
Metaline Falls developed as a lead-zinc mining community in the early 20th century; remnants of that era are still visible in nearby roads and old work sites.
