Tennessee Hollow is a path along a watershed and it's better in the winter when there is water in the creek. There's a parking lot off Presidio Blvd that faces the trail. Parking $2.50 per hour. This is nice place to sit in the car with lunch while looking at open space. The main part of the specific Tennessee Hollow is the path between Presidio and Lincoln then cross the street between Lincoln and Gorgas. There are a lot of birds, plants, and flowers in the watershed. I'd recommend going to the Tunnel Tops park afterwards.

** The following review reflects my experience DURING the COVID-19 pandemic. **…read more I don't know what a 'hollow' is, but then again, I don't understand what a lot of things mean. I'm assuming Tennessee Hollow refers to the valley that this trail follows in the Presidio. Otherwise it's my brain that must be hollow because I have no explanation for the Tennessee part of the name. All I know is that it's a two-mile route that I walked north to south and back again. I started at the Crissy Field Marsh on the Golden Gate Promenade. That's where I crossed a couple of footbridges through the newly excavated Quartermaster Reach Marsh (photo: https://bit.ly/3cyrZ51). There wasn't much to see here yet except the underpass of the Presidio Parkway. I eventually made it to Lovers' Lane Bridge which didn't strike me as a spot for a romantic tryst (photo: https://bit.ly/3eIdnmr). I walked along the residential MacArthur Avenue until I found myself at the legendary El Polin Spring. Lots of kids were frolicking around the stone wells (photo: https://bit.ly/2PYDGdH). I climbed up to the Ecology Trail passing by a redwood grove (photo: https://bit.ly/38EjX9Y) and made my way back by taking a detour through the Main Post. It was a pleasant walk, quite scenic in parts though heavy on pavement for some stretches, but a good way to get acquainted with this hollow...or maybe it's a watershed. It doesn't matter because I don't know what 'watershed' means either. RELATED - Up for a hike? Here's a collection of trails I've walked and reviewed: https://bit.ly/2OrC8nUl

There are several different maps on site, featuring the golden gate national recreation area (beaches, wildlife, historic former military installations), points of interest in the presidio, hiking and biking trails, and transit options. A couple of benches allow for seating, and it's certainly a lovely space for relaxing among nature. But it's hard to just sit back when there are such lovely views all around, to explore. Looking over the concrete edge, you can see the water in the distance with sailboats floating by and the islands of the SF bay adding to the scenery. Beautiful landmarks can be seen, like The Palace of Fine Arts and Alcatraz. Toward the right, former military buildings of the presidio, as well as SF residences lining the hills. And trees and greenery. LOTS of trees! You would think they are partially blocking the views. But the way I see it, they make the views what they are... captivating!

Fort Miley is located between Lands End and the VA Medical Center on Point Lobos covering 54 acres on prime real estate that the federal government purchased for $75,000 in 1891. That's equivalent to approximately $1.9 million dollars in today's rate. It sat empty for several years until the U.S. Army started the fortification beginning in 1899 and completed in 1902. Over the years, they added garrisons, barracks and other improvements as it was the first line of defense for the city. However, they also built on top of a huge cemetery, which they promised to move and relocate. Additional construction for the Palace of the Legion of Honor in 1993 determined that this was not the case as the digging led to discoveries of bodies and coffins underground. This means that only the headstones were removed while the bodies remained in place. I'm not the least bit surprised since how many times has the government lied to the general public. But how morbid is that? One could easily get lost here as there are many places to explore or if you're hiking Lands End and make this a part of your trail for additional challenge. I don't mean lost as in can't find your way back, but lost as in one can easily wander and get carried away. That's what happened to me the first time I was here as I spent hours exploring and studying the history of this place. Local teens also use the area as their skate park and I can't fault 'em since they're using the space to their advantage. There are numerous graffiti on the walls, and some of 'em are very impressive and artistic. One can learn to appreciate this form of artwork while others may disagree. But beauty is in the eye of the beholder. Don't be surprised if you encounter a homeless encampment here or even actual homeless people. If you go deeper in the woods, just keep that in mind. Also, if your bike is stolen, there's a chance it may turn up here. Just take extra precautions should you decide to check it out. According to historical records, this vantage point used to have a clear view of the Pacific Ocean and all around the bay. Now, most are covered with tall trees, but I am fine with that. The same trees provide a canopy and shelter from the hustle and bustle of the city that one can find relaxing. I can easily seat on the bench while meditating to get rid of stress and forget one's worries. There is a clear patch of land on the west side with a lone picnic table overlooking Ocean Beach. I've seen some people flying their drones here, but I just gaze at the amazing view since you can see as far as Pacifica from here. This could also be a great photo-op for weddings or any celebrations that may come to mind. Fort Miley is named after Lieutenant Colonel John D. Miley, who passed away in Manila, Philippines in 1899 at the young age of 37. That's like some six degrees of Kevin Bacon, right there.

I went here and felt safe.

They aren't all connected yet, so you can sort of pick and choose which segment you want to go on. The trail is designed and maintained by a lot of wonderful volunteers, who do this as a labor of love. So special kudos to all those wonderful volunteers! Today, I hiked the Trail section at the Hamilton Wetlands. It's pretty easy to get to and the trail is well maintained. However, I did not see any drinking faucets, and there were just a few out houses. Many of the trails are excellent for young families. Today, I saw a ton of families, even with little kids riding bikes with training wheels. At the Hamilton Wetlands, keep in mind that the internet is almost nonexistent. This proved to be a big disappointment, since I wanted to run some of the Vizzit places audio tours. But I had to give up on that. Nevertheless, the San Francisco Bay Trail is a wonderful project, with a ton of places to visit. I recommend you try different segments that are appealing to you. Don't forget to check out the Vizzit application, which has audio tours for some of their segments.

There is a trail head just in front of the parking spots or you can catch it at the back of the church. This trail cuts across the bottom of the Old Hillary Preserve - imagine the preserve is a wedge and the trail cuts across the point of the wedge. It ends on a residential street - Vistazo West, where we then hiked up the hill - linking to Lyford Dr. It's pretty steep, but eventually you get to another trailhead from Lyford. You may want to turn left up Sugar Loaf and then Right on Heathcliff Dr, but it was pretty steep and we decided to stay on Lyford, which also leads to a trialhead for Fishbits. Once on the trail head you climb to the top with the trail's clear hills and valleys ,and have amazing views of the bay, Angel Island and the Golden Gate and Richmond Bridges. If you take this to the end - you will be greeted by a "No Trespassing -Private Property," sign just outside a wire fence that has been cut open - clearly some time ago. We proceeded and there is another sign posted right at the lookout point for Angel Island. Taking this trail around - there are now houses on the left which are enclosed by chainlink fencing. At this point, you may want to go back on the main trail or if you proceed, the trail gets a bit more narrow and challenging - uneven, less groomed, some rocks, etc. but clearly more than a deer trail. It cuts across the mountain and then switches back towards the trail behind Old Hillary's Church. All Trails lists this a down and back trail and not a loop. We kept going and it did eventually loop back to the church. It was just short of 4 miles, steep, and took us 2.5 hours and I'm not in great shape. So there you have it!

One of my absolute favorite field trip spots for my students is the Wood Line in the Presidio of…read moreSan Francisco. This is a super popular place for professional photos. A quick tip: because of the way the Wood Line is designed, this stretch can turn into a full-on wind tunnel. Definitely layer up; it can get chilly even on a sunny day. What makes this area so special for young students is the natural layout. The rows of eucalyptus trees create built-in boundaries, which makes it much easier to manage a group while still giving them a sense of freedom and exploration. There are also spots nearby where kids can build and expand on makeshift shelters using fallen branches, perfect for imaginative play, teamwork, and a little hands-on engineering. There are often dogs off leash in this part of the Presidio, but we've never had any issues along this particular stretch. One especially memorable visit included spotting an owl nesting in the trees. A park ranger was stationed nearby to ensure the owl's safety, and my students even got to ask questions and learn more about the habitat. It turned into an unexpected and magical lesson in urban wildlife. If you're looking for a unique, outdoor San Francisco, add the Wood Line to your list.
