Overview

6th Street Connector Trail + Bluebell Hiking Trail + Bluebell Road Trail + 3 more trails out and back is mapped as a trail of 4.46 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 5,689 ft and 7,151 ft above sea level, a difference of 1,462 ft.

Mapped along or near the trail: 1 climbing area.

Estimates

  • Estimated time 2 hr 20 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.

Starts at a derived trailhead (1 mapped trail start within 150 m), 339 m from mapped parking; 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.
