I'm searching for a outdoor location for a wedding ceremony... What do I need to do if I want to use this location and what will it cost? Also are there any nearby venues for a reception?

The office is on pv drive up from 5 points.

Like others mentioned you have to contact the park to reserve a spot in the park.

There are signs at the park with phone numbers to reserve a spot I don't know of any place nearby to have a reception

If you go to the park they have signs with numbers to call to reserve space at the park.
