Best time to go

Spring and fall

Mild shoulder seasons offer the best footing and steadiest flow. Spring runoff can make surrounding ground muddy; late summer flow may drop.

Effort

Easy access

Usually a roadside pullout or a short, gentle path — often under a mile with little elevation change. Good for casual visits and most fitness levels.

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
A way to filter or purify water if you intend to drink
