Yep, there's a link to that trailhead in my post. This is good info especially the part about the parking signs...at rush hour they tow all parked cars on Los Feliz. I think Brukuns could probably handle the walk from Los Feliz, but it sounds like there will be a 3 year old accompanying them so parking near that trail may be the best option if not taking the DASH, it wouldn't be too hard to carry a 3 year old up the trail if she can't do the hike herself.If you’re reasonably fit just walk from Los Feliz. Park around Los Feliz and Hillhurst. Just make sure you check the parking signs on Los Feliz if it’s during the week. If it’s the wrong hour they tow like clockwork. Go get a sandwich at little Dom’s deli. Maybe spot a celeb. Then walk up Hillhurst to Vermont. The trail to the observatory goes up on the left just before the Greek theater. It’s a good little hike and there’s plenty more above the observatory if you want it. I used to live right there and did it several times a week.
