The SA River trail worked wonderfully. A great non-stop ride for the last few miles of my trip!
A few tidbits for anyone else who might follow
- the trail is intended to hook up with the southern terminus of the Huntington Beach trail. As such, there are no obvious markings or signage for anyone on a bike cruising down PCH. I guess I was expecting some dramatic signage
If southbound, you need to get off the road and onto the bridge sidewalk, to connect to the beach trail which circles under the bridge onto the river trail. Or, just get on the beach trail at any number of opportunities prior to reaching the SA river.
-for a while you have a choice of riding on either side of the river. The south path is paved, north has dirt/pea gravel.
-At one point the south side path terminates thanks to the Riverview Golf course. There is a rusty iron bridge to carry you to the north side, where the paved trail continues. The intended turn at the bridge is not well marked; only a bit of striping on the pavement tells the tale. Miss that and you may be wondering why you've turned off onto a baseball field
But again, it's a great ride.
