River Crossings: When to Turn Back, Where to Cross, and How
The danger in a river crossing isn't depth — it's current, cold, and a pack that pins you under. Decide first, pick the right spot, and cross with your hip belt unbuckled.
The risk in a river crossing is not water depth — it is current speed, cold water, and a soaked pack pinning you face-down. If the water is above your knees, the current knocks you off balance, or the water is near-freezing, do not cross: wait, detour, or change the route. Unbuckle your hip belt before stepping in, face upstream, and shuffle sideways with two points of contact.
Most river crossings are decided badly before anyone steps into the water. The question is never "how deep is it?" — it is "how fast is it, how cold is it, and what happens to my pack if I fall?" There is no river you have to cross.
Decide First: Cross or Don't
- Water above your knees, a current you can't stand against, near-freezing water, or a waterfall, rapid, or fallen log downstream: don't cross — wait, detour, or change the route.
- Glacial streams run lowest in the early morning; they rise fast in the afternoon and after storms.
- Mark backup crossing points, backup camps, and exit routes before you commit. Never bet the whole trip on one crossing.
Pick Your Spot
- Choose a straight, wide, braided section — where the current splits into channels, the water is shallower and slower.
- Avoid the outside of bends, standing waves, fallen-log strainers, slippery boulders, and anywhere above a waterfall.
- Walk the bank upstream and downstream to find a spot the whole group can cross — not just the strongest person.
How to Cross
- Unbuckle your hip belt and sternum strap. If you fall, you need to shed the pack fast — a soaked pack floats just enough to pin you face-down.
- Use trekking poles or a solid stick and keep at least two points of contact. Face upstream, lean slightly into the current, and shuffle sideways — no big steps.
- Look at the far bank, not at the eddies around your feet.
- In fast or deep water, cross as a group: the strongest person breaks the current upstream while the rest hang onto pack straps or arms, forming a line or a triangle. Do not hold hands in a horizontal row — one person falling takes everyone down.
- Wear shoes, or dedicated water shoes if you carry them. Never go barefoot: you lose grip and invite cuts from rocks and debris.
Once You're Across
- Dry off immediately and change into dry socks and clothing to prevent hypothermia. Hot drinks if you have them.
- Confirm everyone in the group is across before you move on.
Common Mistakes
- Crossing with the hip belt buckled — the single most dangerous habit.
- Following someone across because "they made it."
- Crossing a glacial stream at noon or right after a storm.
- Going barefoot or in flip-flops to keep your boots dry.
