Celebrating San Francisco's Birthday
This weekend, the 241st birthday of San Francisco is a wonderful opportunity to visit the Presidio. You can enjoy the activities at the Main Post or take a wonderful hike around this former military installation. There is also opportunity to go indoor rock climbing or spend some time bouncing around the House of Air. Regardless if your interest is history, exercise, or excitement, this is a wonderful spot to spend the day. The museum at the main post is always a lovely stop.

The celebration in the Presidio marks the founding of Mission Dolores (the Presidio was formally founded in September of that year).

And if you’d like a bit more about how San Francisco was discovered by the very lost Portola expedition who were trying to create a settlement at Monterey Bay and walked right past it:
