Confused At Henry Cowell...

I visited Henry Cowell State Park today for the first time. I went with some friends. We parked somewhere along highway 9 and moved fast towards the San Lorenzo river. By the time we reached the water we’d already gone on a few sketchy trails and we were gonna go on more questionable trails along the river towards The Garden Of Eden. A few of us didn’t feel comfortable going that way so we all turned back the way we came then followed the train tracks to the swimming hole. There were a few people there, including an annoying group playing music really loud on their portable speaker. We hung out for a little while before following the train tracks some more then heading back to our cars. The maps I brought, and my phone’s gps, weren’t very helpful because we didn’t enter through any of the designated entrances and there weren’t any trail markers anywhere. I still had fun but next time I’ll come better prepared and take my time and really enjoy it.
