Waterline Trail

The Walk

Come at it from below, off Leif Erikson Drive, and the climb starts almost immediately. It crosses the Wildwood Trail near milepost 24 and keeps grinding upward toward Skyline. What makes the grind worth reading is what’s underfoot: this ridge is a watershed divide. Rain landing on one side drains south into the Springville Creek system; rain on the other slides north into the Linnton Creek drainage. You are, quite literally, walking the seam between two watersheds — a piece of hydrology usually invisible, made legible here by the shape of the land you’re sweating up.

The upper reach follows Committee of Fifty Creek toward its headwaters, and that name is worth pausing on.

Local Lens Committee of Fifty Creek carries the name of the citizens’ coalition that fought Forest Park into existence — some forty civic organizations that banded together in the 1940s to turn these hillsides into a public forest instead of a subdivision. That coalition never really disbanded; its through-line runs straight to today’s Forest Park Conservancy. The creek you’re following uphill is named for the people who made sure there was still a forest here to climb through.

Then the trees open. The water tower and reservoir sit in that broad mowed meadow, and after a morning of canopy the sudden sun and sky feel almost strange — a rare, uncanopied breather in a park that specializes in shade.

Runner’s note If you want a lung-burner without leaving the north-central trails, this is it — a short, honest climb with real vertical, muddy enough in the wet season to punish careless footing. Repeat it if you’re training; the Wildwood crossing at milepost 24 makes a clean top or bottom marker for intervals.

Before you go

Mud Truth: this ridge holds water, and the tread remembers every storm. In the wet months expect it slick and eroded — stay in the center of the tread rather than skirting the puddles, or you’ll help widen the very trail you’re eroding. Save it for drier weeks and a clear day, when the firmer footing and the open sky at the top are both actually on offer. And go in daylight; it’s a short, unsigned, informally named climb, not a place to be sorting out junctions at dusk.

Stand a minute in the meadow before you head back down. It’s not a grand view, exactly — but the sky is a novelty here, and the forest closes back over you soon enough.
