Grinnell Falls

Grinnell Falls · PinnedAtlas

Overview

What to expect

A cascade where water drops over rock. The payoff is the falls themselves — mist, sound, and often a pool below. Rocks near the water stay slick, and the best viewpoints can require care to reach. Plan for a genuine outdoor outing to reach it.

Field notes

Plan your visit

Best time to go

Late spring (peak flow)

Flow is strongest during and just after snowmelt or the rainy season. By late summer many falls slow to a trickle. After heavy rain they roar — but access can be dangerous.

Effort

Moderate hike

Expect a real walk: roughly 1–3 miles round trip with some elevation gain or uneven footing. Wear proper shoes and give yourself time.

What to bring

Plenty of water
Sturdy, closed-toe footwear
Offline map or downloaded directions (signal is often weak)
Tell someone your plan and expected return time
Shoes with grip — wet rock is slippery
Dry bag for electronics
Swimwear if you plan to get in
