## What is Cavio?

Cavio is your underground expedition companion for cave explorers.

From gentle limestone galleries to technical river conduits, Cavio brings cavern routes, gear planning, science archives, and a trail community into one place—so first-time cavers and experienced teams can prepare smarter and go deeper with confidence.

CAVERN ROUTES
Browse curated cave dossiers with difficulty grade, passage length, max depth, cavern type, highlights, access notes, and best season. Decide whether a route matches your skill before you leave camp.

GEAR MANIFEST
Switch difficulty levels and instantly build a pack list—helmets, headlamps, footwear, layers, rope systems, and more—so packing stays clear and purposeful.

SCIENCE ARCHIVE
Learn how karst landscapes form, how stalactites grow, and how underground water systems behave. Field tips help you protect fragile formations and explore more responsibly.

EXPLORER COMMUNITY
Share cave stories and trail photos. Read Field Oracle briefs on gear, rope craft, cave photography, and seasonal wisdom from explorers under the stone.

TRAIL FRIENDS & MESSAGES
Add trail partners, manage friend requests, and chat with friends before and after your expedition.

EXPEDITION PROFILE
Build your explorer identity and track caverns visited, rope hours, and activity mix—your personal underground rhythm, visualized.

Light your lamp. Enter the hollow. Explore with Cavio.
