Its a fantastic hike that rewards you with amazing east and west views. If you do the full loop, you will experience an 860 elevation change throughout. So there are some slopes, but its still would rank as relatively easy. It is not suitable for mountain bikes. The trail is well marked, but make sure you have enough daylight to complete the loop. The loop takes about 50 minutes for me to complete. There's also an easily accessible bathroom 3/4 of the way through the loop that's maintained by the parks people. There is no water, so bring your own. And no cell phone coverage on the hike. Which is delightful!

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

We're all shuffled off to Angel Island or Sam's Anchor Cafe to congregate away from the downward eye-line of the wealthy locals. The one exception is this 2.6-mile trail which really isn't a trail. It's more like a paved promenade that won't make you break out in a sweat unless it's a hot summer day where you're fully exposed. It starts at Blackie's Pasture where surprisingly, there's free parking. The walkway winds along the picturesque shoreline of Richardson Bay to downtown Tiburon offering gorgeous views throughout. Nothing to complain about except the occasional spatially indifferent cyclist who thinks that grazing innocent pedestrians is sport. There's a worthwhile detour onto San Rafael Avenue that will get you up close and impersonal with Belvedere's exclusive waterfront real estate. The walk back to your car is just as good as the walk to Tiburon. Just don't let all the surrounding privilege get you down. RELATED - Up for a hike?

ACCESSING JEWELL TRAIL. On two occasions in February 2021, I hiked the loop trail consisting of…read moreBolinas Ridge Trail, Jewell Trail, and Cross Marin Trail. My hike was in the counterclockwise direction around this loop trail. The final stretch of this loop hike requires hiking within the narrow space between the Francis Drake Blvd. and a steep downhill slope covered with trees and with lichens called "old man's beard." Jewell Trail has two trailheads. One is located on Bolinas Ridge Trail and the other is on Cross Marin Trail. The trailhead for Bolinas Ridge Trail is next to Francis Drake Blvd., one mile east of Olema. The trailhead on Cross Marin Trail, is situated one mile to the northwest of the Camp Taylor campground. Regarding the Bolinas Ridge trailhead a mile east of Olema, typically between five and ten automobiles are parked here. They're parked on the south shoulder of Francis Drake Blvd., but additional parking places are available on a wide dirt shoulder, across the street and 50 feet to the west. The segment of Bolinas Ridge Trail leading to the Jewell Trail Trailhead provides scenery of amazing beauty. The photographs in the following list describe, by way of pictures, everything that I could possibly describe with words about Bolinas Ridge Trail and Jewell Trail: (1) Photo of wooden maze that allows passage of people, but prevents cows from passing through. The body of the cow is not flexible in the same way that snakes are flexible. If cows were flexible, they could be taught to dance the hula. But cows are unable to do hula dancing. Because cows are not flexible, they cannot pass through the wooden maze. (2) On the left side of Bolinas Ridge Trail, you can see a cluster of trees sitting on a hillock, with a row of stones embedded in the hillock. This hillock occurs about 100 feet down a grassy slope. (3) Same cluster of trees sitting on a hillock, where photo shows a tree coated with "Old Man's Beard" lichens. (4) To the right of Bolinas Ridge Trail is a deep valley. The boulder at the far left has lichen clinging to it. (5) On the right side of Bolinas Ridge Trail is a tall boulder with a stone shelf on it. On this stone shelf, I posed my mountain goat. While taking this photograph, a man and woman, in their 20's, were hiking by. I turned to them and said, "Don't worry, my permit for keeping the mountain goat is all paid up." They responded with a flurry of laughs. (6) Same boulder, with both Strawberry Shortcake and the goat. (7) Photo of deep valley to left of Bolinas Ridge Trail. Jewell Trail is just beyond this valley. (8) Photo of the sign at the trailhead for Jewell Trail. Two men were approaching, riding their mountain bikes. I was impressed by their ability to ride up the steep hill and I said, "You are certainly strong and powerful, but I know you are vulnerable to KRYPTONITE." They understood my joke and laughed. (9) After a minute of hiking down Jewell Trail there's a huge boulder to the right. Photo of the goat, California quail, and northern flicker sitting on this boulder. (10) Further down Jewell Trail, view looking uphill at the beautiful upper part of the valley. (11) Same location by Jewell Trail, with view looking downhill. Francis Drake Blvd. can be seen in the distance. (12) Further down Jewell Trail, the forest begins. Goat and Strawberry Shortcake stand near a zig-zag in the trail. (13) Further on down, the trail enters a shady area, covered with a tunnel of trees. I arranged a fallen white-colored branch, possibly from a birch tree, so that it would show up in the photograph. (14) Photo of a mossy tree covered with a few tiny ferns, located next to Jewell Trail. LICHENS. In many areas of your hike, you will find lichens hanging from trees and lichens growing on rocks. The kind of lichen that hangs from trees is "old man's beard," also called beard lichens of the genus Usnea. Photographs of beard lichens are available from, "pointreyesnature dot com/alamea-trail" and also from Kundsen and Carlberg (2005). Other kinds of lichen at Bolinas Ridge include Rimularia insularis and Rinodina falvosoralifera. Colorful lichens that grow on rocks include, Xanthoria elegans, Rhizoplaca melanopthalma, and Saxicolous lichens. REFERENCES. ( 1 ) K. Knudsen and T.

The trail forks right before going to the Legion of Honor so if you take the left side the trail takes you through to the street going through the SF VA Medical Center.

A couple of notes: *The Trailhead on the Clement End starts at 40th Avenue. *There are restrooms located on the north end of the trail. *It's also easy to miss the start from this side. It's just to the right of the tee box behind the museum. *Keep an ear open for "Fore!" as you are right along a golf course.
