Overview

Baseline Trail + Bluebell-Baird Trail + Bluebell Road Trail + Bluebell Hiking Trail loop is mapped as a loop of 1.94 mi in Boulder Open Space and Mountain Parks.

It runs between 5,661 ft and 6,155 ft above sea level, a difference of 494 ft.

Mapped along or near the trail: 2 viewpoints, 1 historic site.

Estimates

  • Estimated time 55 min one way by Naismith's rule, which assumes steady walking and adds time for climbing. Real time varies.

Before you rely on this

  • Water points are mapped nearby, but mapped is not tested or guaranteed: treat any water and carry your own.
  • 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% (2 climbing in red, 3 descending in blue).
Steep sections (5)
  • 0.54 mi to 0.72 mi: about 19% uphill (from the elevation model, so rough)
  • 0.77 mi to 0.87 mi: about 14.2% uphill (from the elevation model, so rough)
  • 1.10 mi to 1.17 mi: about 15.8% downhill (from the elevation model, so rough)
  • 1.26 mi to 1.31 mi: about 14.7% downhill (from the elevation model, so rough)
  • 1.34 mi to 1.41 mi: about 13.4% downhill (from the elevation model, so rough)

Starts at a derived trailhead (2 mapped trails start within 150 m), 19 m from mapped parking; the route starts at the nearest mapped trail junction, 51 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.
