Hiking Trail Directory rates this route hard from the available distance and elevation measurements. That rating is useful for comparing routes in the directory, but it does not establish technical terrain, exposure, path condition or the skills required on the day. The start and finish differ on this point-to-point route; arrange the return journey before setting out.
The source data records route tags for river and membership of the lwn network. These attributes describe the route record as a whole; they do not prove that every section has the same surface, signage or feature.
The directory season field highlights april to october. This is planning metadata, not a live statement about snow, closures or trail condition. Walnut Creek is the nearest linked city in the directory, approximately 2.5 km away in a straight line. The route record names East Bay Regional Park District as operator.
The map is derived from OpenStreetMap and contains 150 geometry points. Elevation values were sampled from terrarium-z11. The traceable source record is 1354568. Open-data records can lag behind reroutes and closures, so compare the source, official notices and the forecast before travelling.
Plan around this route’s details
- Start, finish and return
- The recorded 19.2 km line has different endpoints. Confirm travel from the finish before setting out; that return journey is additional to the mapped route.
- Climbing in context
- The recorded ascent averages approximately 24 m of climbing per kilometre across the whole route. This is climbing density, not trail gradient: climbs and flatter sections may be unevenly distributed. Recorded descent totals 446 m and also needs time in your plan.
- What needs a separate check
- This record does not establish surface, dog access, wheelchair access. Check any of these that affect your group. Current closures, access arrangements and transport are not verified by the route line.

Your walking-time scenario
Adjust the example pace and allowances to explore your own plan. This calculator uses your inputs, so it may differ from the directory’s headline estimate.
Calculated walking time including your allowances
6 hr 4 min
288 min for distance + 46 min for ascent + 30 min allowance.
Formula: distance ÷ pace × 60 + ascent ÷ 100 × climbing allowance + stops. Travel to and from the route is additional. Terrain, descent, weather and navigation are not modelled. These results do not establish route suitability. Read the time-planning guide.

Tips from the trail
- Open the linked source record before departure to check whether the mapped relation has changed.

Warnings
- This guide does not contain live information about closures, hazards, snow, flooding or path condition.
