If you’re driving with GPS, the address is 5000 Sunnyside Road, Anmore. The parking lots are 2 km from the park entrance. You’ll likely lose cell reception shortly after entering the park – NOTE – To get good cell reception, you’ll have to do some hiking; reception is good on some areas of Buntzen Ridge (Diez Vistas Trail) and Eagle Ridge/Mountain. You’ll get spotty reception on the Buntzen Lake trail.
Here is a link to the parking lots: (Google Map)
