When I was there in early September, I drove up around 6am, and all spots right by the Memorial were already taken. There is a large parking lot a couple of hundred yards downhill, which was perfectly workable. I did not see any signs pointing to time constraints.

We brought our dog and didn't have any problems

I suggest driving up the road to Torrey Pines for a nice hike thats very close by. Look for the Gliderport! Or park near the Torrey Pines state park.

Yes -- plan to stay for sunset..

It doesn’t take long at all. It’s really up to you how long you decide to stay. We were probably there walking around for 45 mins.

Holiday Inn Express & Suites in the La Jolla beach area is less than a mile from Mt. Soledad is probably one of the cheapest and it includes Free Parking, Free Breakfast, Free Internet. Good Luck

The slope up is pretty gentle and yes, it is accessible from all 360 degrees, however there are stairs to get to the foot of the cross itself. You wont be disappointed tho, its breathtaking

The cross can be seen from many miles away--- then when you drive up the winding, paved road to it, it is amazing.
