The Northeastern Corner of L. A. County
The creek (or wash) is only a concrete-lined ditch at this point; but the City of Claremont has landscaped a creekside park with an inviting bike path, benches, water, etc. The path runs less than 3 miles, and south of Base Line it may be locked off, but Puddingstone isn’t far to the southwest, or else go south past the Botanic Gardens and onto the campus of the Claremont Colleges to get a longer ride.
