Cycling Notes:
To get on the bike path, you have to go through gyrations: take Moraga Way southbound (you have to loop around the station a bit, follow the signs), then get over to the left to turn left at the first light, into downtown Orinda. Take your first left past the Orinda movie house, then turn right on Bryant Way, right on Davis Road, and onto the sidewalk/path just before Bates Blvd. The St. Stephen’s bike path is uninspiring but useful; it parallels Highway 24 between Orinda and St. Stephen’s Road, which turns out to be the most direct and least hilly way between Orinda and Lafayette. The path is separated from the highway, and doesn’t get much foot traffic, so it’s reasonably pleasant. It climbs gradually for most of its length.
El Nido Ranch Road is a wide residential road with little traffic. It descends gradually to the Lafayette city limits, and then there’s a fast downhill curve leading up to a terribly-placed stop sign just before the freeway entrance. Blow through the sign, and prepare to turn left on Upper Happy Valley Road, the next stop sign.
Upper Happy Valley Road is wooded and residential and has little traffic. It climbs gently for a while and then has a short, steeper section (but it’s not too bad). It ends at Happy Valley Road, which is also wooded and residential, but is wider and has slightly more traffic. It has a reasonably nice descent, but the pavement isn’t that great. It descends all the way to the BART station. Turn left on Deer Hill Road just before the BART parking lot. (Or bail out at BART).
Deer Hill is a wide road with moderate traffic. It has a couple of short climbs and short descents, then a short, steep climb and a short, steep descent to a stop light at Pleasant Hill Road.
Pleasant Hill is a busy, wide connector to Reliez Valley, which is wooded and narrower with less traffic. It used to be rural but now increasingly has McMansions and related cars.  There’s a relatively short, steep climb followed by a fast, fun descent, where it enters into more rural territory.
Reliez Valley becomes Alhambra Valley (go straight, not right), and traffic levels drop to near zero after the intersection.  It starts with hills rolling gradually upwards, which tend to sap your strength if you attack them too aggressively early.  After emerging from the wooded area there’s a serious climb (Pig Farm Hill) followed by a fast, long descent which ends at Bear Creek Road.
Bear Creek is one of my favorite roads; wide and pretty with steady climbs and lively descents. It has two significant climbs, Mama Bear and Papa Bear. Both are straight and even at about 7%; get in a low gear and grind up them. They are also unshaded, so be wary of overheating, and pull over and take a drink if you get hot. After Mama Bear there’s some rolling on the top and then a nice fast descent to the bottom of Papa Bear. Papa Bear lasts just over 1 km, then there’s an awesome fast descent–the only thing to watch out for is the gravel on the shoulders. The road flattens out, then ends with a short climb (Baby Bear, which by this point is often not “just right).
