The ceremony and reception will be on the same property. There will be signs to direct for parking near the venue.
Once you are on Colina Rd, look for the sign that says “Cabins at Red Rock” and turn into the drive way. From there you will go straight until you see a hill that has a gated path going up. At the top of the hill you will see the venue to the left and there should be signs on where to park.
