Dear Banana,
You wrote, "I just want to ride to and from DCHP in lieu of a vehicle." Riding to and from Deep Creek Hot Springs would require you to break a number of laws; riding a motorized vehicle on one of several pedestrian hiking trails, one being the Pacific Crest Trail, a nationally dedicated foot trail that connects Mexico to Canada (or vice versa). To not carry this argument further I suggest you ride your motorcycle on Bowen Ranch Road to the Bowen Ranch, now owned and operated by Mike Castro, pay $5.00 for yourself (if the cantankerous Mike Castro lets you park your vehicle in the designated lot) and then hike to the Creek and Hot Springs and then hike back to where your bike is parked, start it up and drive back to whichever civilization you prefer. Riding your cycle to the springs would require you to know which of the many country dirt roads, and there are many, might carry you the the sacred creek. Using the hiking trails as your own personal motorway is illegal and may have consequences you may not have considered. I suggest you follow the laws and local culture by parking the bike and make the hike to the creek and then back to the lot you parked.
