"What an experience to be able to witness astronomy history ! A lovely drive up to this beautiful observatory! Peaceful and relaxing, lots of history and great views!"

"Driving back to Del Mar after my many sleep-outs in Anza-Borrego (over many years), this seemed like the most opportune time to visit the Observatory.
If it were not for the motorbike/HP-automobile "blast-the-windy-corners" crowd, the drive-up would have been idyllic.
It was just I, a "Father-Daughter" pair, an Odd-Couple, and a random motorbike rider (resplendent in his protective garb). I (basically) had free-reign of the entire Property :)
The sequoias at the Visitors Center (planted c.1945, I believe) are 30m tall, and 230cm diameter DBH...
It was a perfect day to be visiting.
If it were not that the walk-able Observatory doors and the observatory Telescope Doors were not directly aligned (I measured a ~7deg offset), this experience might have smelled like Heaven ;)"
Andy Hurt (ah)
"This is a beautiful observatory, and, at least when we went, it didn't appear to be one that is visited often. The drive up was amazing, and I can completely understand why people with high-performance sports cars might desire to visit. However, it was extremely foggy on our way up, so we couldn't test the performance of our rental...SUV. we essentially had the place to ourselves, and we made the most of it. We spent a lot of time reading through all of the exhibits. It was rather chilly as we went in March, and it was overcast, but we enjoyed the trip nonetheless."
