Are pets allowed? I read that the state park allows pets, but can we enter the mission, and fort compound? That would be such a bad experience if we made our way with our doggy to camp, but not allowed to enter the historic sites.
No pets are allowed inside state buildings or monuments. You may take a pet inside the state park, and pets are allowed at your campground.
Pets are not allowed on the mission grounds of the park, the walled area around the mission building. The are welcome on a leash in the rest of the park. I do not remember if they are allowed in the fort compound.
