Slot Canyoneering: The Complete Guide to Gear, Skills, and Waterproof Packs

What Is Slot Canyoneering?

Slot canyoneering is the art of navigating narrow, water-carved canyons — squeezing through tight passages, rappelling down waterfalls, swimming through pools, and scrambling over boulders. It combines hiking, climbing, swimming, and rappelling into one of the most thrilling outdoor experiences on the planet.

Unlike dry canyoneering, slot canyoneering almost always involves water. Waist-deep pools, chest-high swims, and full submersion are part of the deal. That is why your gear — especially your backpack — needs to handle total water immersion.

Essential Slot Canyoneering Gear

The Non-Negotiables

  • Backpack — Either a waterproof pack to keep gear dry, or a drainage pack for fast water evacuation. See our canyoneering gear guide.
  • Harness — A canyoneering-specific harness with gear loops
  • Helmet — Rockfall and low overhangs are real hazards
  • Rappel device — ATC, figure-8, or canyoneering-specific device
  • Ropes — Static canyoneering rope (not climbing rope)
  • Wetsuit or drysuit — Depending on water temperature
  • Neoprene socks + canyoneering shoes — Grip on wet rock

Nice to Have

Waterproof vs Drainage Packs for Canyoneering

There are two approaches to canyoneering packs, and the right choice depends on your route:

Waterproof (Airtight) Packs — Keep Everything Dry

Best for day canyons and routes where you want zero water contact with your gear.

Pack Capacity Type Best For Price
Coqui 22L 22L Airtight/submersible Day canyons, short technical routes $250
Karpathos 34L 34L + 4L pouch Airtight/submersible Full-day canyons, overnight approaches $300

Drainage Pack — Fast Water Evacuation

Best for multi-day wet canyons where you are in and out of water all day. Water enters and drains fast so you never carry extra water weight.

Pack Capacity Type Best For Price
Mojave 60-70L 60-70L Modular drainage Multi-day canyon expeditions $259.99

Pro tip: Nest a Coqui 22L inside the Mojave as a waterproof inner compartment for electronics and food on multi-day trips.

Safety Tips

  1. Never canyoneer alone — Groups of 3-6 are ideal
  2. Check weather forecasts — Flash floods kill canyoneers. Never enter if rain is forecast anywhere in the watershed.
  3. Get a permit — Many canyons in Zion and Escalante require permits
  4. Take a course — If you have never rappelled, take a course first
  5. Tell someone your plan — Leave your itinerary with someone not on the trip
  6. Carry emergency communication — A waterproof phone pouch can save your life

How to Pack for Slot Canyoneering

  1. For airtight packs (Coqui/Karpathos): Close the zipper slowly and straight. Seal with a friction tug. Trap air for flotation in deep pools.
  2. For drainage packs (Mojave): Use internal dry bags for sensitive items. Let everything else get wet and drain.
  3. Hang wet gear externally — Use pack loops for harness and slings on the hike out
