7 am to 10 pm are the hours , if I'm rembering right
You can come and go anytime between those hours, granted there is a 5 to 10$ charge depending on the time and length of stay, it usually takes me 40 minutes to hike down, and an hour to hike up, give and take , and once I'm at the hot springs time melts away !
You are able to camp at bowen Ranch for the 10$ fee,
Enjoy, look behind you as you hike the trail so you remember place markers!
