It took me a couple hours, but I took my time to enjoy and take pictures. If I was going at a good clip, I could have made the round trip in 80 minutes or so. I definitely recommend planning ahead with the local tide charts - it would have been a bit harder if I was paddling against the current. You also need to watch for the winds; they can be stronger than the current. The wind gets funneled down the canyon from the ocean and can make the return trip challenging.
