Overview

Red Rocks Trail + Red Rocks Spur Trail + Mount Sanitas Trail + 2 more trails out and back from The Peoples' Crossing Trailhead is mapped as a trail of 4.36 mi in Boulder Open Space and Mountain Parks. It is not a loop: you walk it one way or out and back.

It runs between 5,440 ft and 6,070 ft above sea level, a difference of 630 ft.

Estimates

  • Estimated time 2 hr 5 min one way by Naismith's rule, which assumes steady walking and adds time for climbing. Real time varies.

Before you rely on this

  • No water source is mapped for this trail. That may only mean nobody has mapped one, so carry your own water.
  • Check the land manager for closures, seasonal rules and permits before you go; none of that is verified here.

Hover, tap, or use the arrow keys on the chart to read a point; it is shown on the map too.

Elevation along the trail from start (left) to end (right) as drawn. Values are computed from USGS 3DEP 1/3 arc-second DEM (public domain), sampled about every 10 m and smoothed. Shaded bands are sections steeper than about 12% (6 climbing in red, 7 descending in blue).

Starts at a derived trailhead (1 mapped trail start within 150 m), 21 m from mapped parking (The Peoples' Crossing Trailhead); the route starts at the nearest mapped trail junction, 0 m from that point. Built by Arête from the graph of mapped trail segments (OpenStreetMap). Segments join where their ends are within 12 m of each other or one ends on another's line (a T-junction). A loop returns to its start without repeating a trail section; an out-and-back goes to a mapped trail end and returns the same way, so its length counts both directions. Names come only from the mapped trails it uses. Length is measured on the joined line; elevation is computed from USGS 3DEP. Not an official or recommended route.

Length is measured from the route geometry in the source data, so it can differ from signed or official distances. Gain and loss describe the direction the line is drawn; the route view above shows the other direction and out and back. Elevation is computed from USGS 3DEP 1/3 arc-second DEM (public domain), sampled about every 10 m and smoothed.
