Dude you're in luck, the best Led Zeppelin cover band on earth is playing for free at Lake Arrowhead Village on Saturday June 17th, and from the concert it's only 25 minutes drive to the Bradford Ridge trailhead....the hot springs is all downhill from there.
"Led Zepagain" is a very polished group of Zeppelin clones, and even Zeppelin themselves sometimes played worse.
Reserved seats are for the rich Arrow-heads but it's free for all the hot springers, flower punks, hippies, Led Heads, PCT trippers and anyone else who wants to rock .
It's part of an entire summer of free concerts. 6:30 pm to 8:30 pm.
