I have been on part of that trail; it's packed with cyclists at this time of year. I would say more than half will be able to help you with directions. If I remember, the trails are all numbered, too, so that helps. We were on a supported tour, but riding back to the hotel alone on a 98 degree day. I was about to lose it from the heat, when we somehow got off the correct trail, but with not a lot of work, we were able to find our way back to the right place.
