While there’s lots of hiking in and around Lake Havasu City, Needle mountain loop trail is the only one we’ve been on that has remnants of rock stars and million dollar gold mines! The Needles trail is about 30min outside of Havasu and just short of crossing the bridge to California.  However, getting to the actual trail head is a bit tricky and directions can be dicey.  It's a good thing our friend Doug has a Jeep.
