Per the add Google maps it looks like it's outside Longmont by St Vrain State Park. I recommend taking Hwy 119 West/SW to Boulder, turns into Foothills Parkway south to Table Mesa (south side of Boulder), west to Broadway/Hwy 93 south to Golden then West on I-70. Also recommend leaving after morning rush maybe after 9a and getting out of Boulder before 3p.
