The trailhead is off Ortega Highway east of Casper’s. Make a left at the Lazy W Ranch sign. Not sure the road name but you can Google “San Juan trail parking”
@@raulrodarte9553 you can shuttle to Blue Jay and ride down to Cocktail Rock. It’s about 4.5 miles with a bit of technical climbing. I prefer to ride up from the bottom to save the 40-minute shuttle time
