Presidio: Inspiration Point – Golden Gate Bridge Loop

So far, Brett’s intro to Bay Area trail running had taken me to the Marin Headlands and Pt. Reyes National Seashore — outstanding areas in which to run and hike, with great scenery, terrain and courses. An area that might be overlooked by a visiting trail runner is the Presidio. That’s where we were running this morning.

Warm weather had chased the fog away. Saturday, the high temp at SFO was 89 degrees, and today the high was forecast to be in the 90s. So it wasn’t a big surprise that at 7:30, the temp was already near 70 when we descended the stairs at Inspiration Point. (SFO would set a record high of 93 later in the day.)


Brett at the start of the East Battery Trail on our Presidio loop trail run.
Our loop started on the Ecology Trail and then worked down through the Main Post, under the 101, across Crissy Marsh, and onto the Golden Gate Promenade (Bay Trail). From the Promenade there were iconic views of San Francisco Bay, Alcatraz, Marin, and the Golden Gate Bridge. Just past the Warming Hut we turned up the East Battery Trail stairs, and then continued west, under the southern abutments of the bridge.

Here we followed the Coastal Trail past several 100+ year old defense batteries, to another nice overlook of the Golden Gate. After clambering up on one of the battlements, we headed east to Fort Scott and picked up the Bay Area Ridge Trail. This segment took us through the Presidio’s trademark pine, cypress and eucalyptus forest to the high point of the course near Rob Hill Campground, then along the Presidio Golf Course, and finally down past Andy Goldsworthy’s cypress spire to the car. From the point of view of this out-of-towner, the course was spectacular, and it’s hard to imagine an urban run with more variety!

Our particular loop worked out to about 5.5 miles, with an elevation gain/loss of about 450 ft. Here’s a Presidio Trust map of Presidio Trails and Overlooks (PDF), a NPS Presidio Map, and a Cesium browser View of a GPS trace of our loop.

I had a great time in San Francisco, and can’t wait to get back and see more… Thanks Brett & Amanda!

Point Reyes: Sky Trail Keyhole Loop

Sprawling eucalyptus on the Coast Trail, near the Sky Trail junction, in Pt. Reyes National Seashore.

Like an Ent, of Tolkien’s Middle Earth, the huge tree hummed softly. We were on the Coast Trail in Point Reyes National Seashore, near Kelham Beach, about halfway into a 14.5 mile hike/run. We’d paused under the sprawling limbs of the Tasmanian blue gum to enjoy its shade and eat a quick snack.


Pt. Resistance and Pt. Reyes from the Sky Trail, near its junction with the Coast Trail.
Rather than the singing of an Ent,  the resonating buzz was from the wing-beats of many thousands of bees, foraging in the tree. But, it was certainly the kind of day an Ent would relish. Instead of fog and chill gales, the day was warm, with just enough of a breeze to tickle a leaf. Below the bluff, a lazy ocean lapped at the shore, barely mustering enough strength to generate an occasional wave.

Awed by the size of the tree, Brett, Amanda and I joined hands to create a crude measuring tape, but our combined reach only encircled about half of the trunk. We estimated its girth at chest height to be about 30 ft! An oak tree this size would be ancient — perhaps several hundred to a 1000 years old. But, eucalyptus followed the Gold Rush into California, and the tree could be no older than about 150 years!

It was comfortable in the shade of the tree, and we were not in a rush to get back on the trail. Near record high temperatures had been forecast, and the expected 70-80 degree temps along the coast and 90-100 degree temps inland seemed about right.


Lush Douglas fir forest along the Sky Trail in Pt. Reyes National Seashore.
We’d started at the Sky trailhead on Limantour Road, and followed the Sky Trail up through lush Douglas fir forest, past Sky Camp, to the Woodward Valley Trail. Here, at an impossibly green meadow, we had turned off the Sky Trail, and followed the Woodward Valley Trail down the shoulder of the ridge to its junction with the Coast Trail.

Now we had to get that elevation back. Nearby a hummingbird dashed and darted among the peach colored monnkeyflowers, and lodged a territorial complaint as we returned to his trail. In a couple of minutes we turned sharply left onto the Sky Trail and began the steep climb back up the hill.

Tomorrow, a loop through the Presidio and under the Golden Gate Bridge.

Marin Headlands: Bobcat – Miwok Loop

View toward San Francisco from the Miwok Trail in the Marin Headlands.

Drove up to San Francisco to visit Brett & Amanda and sample a few of the Bay Area’s excellent trails.

Within an hour of arriving in the city we were across the Golden Gate, and running up the Bobcat Trail in the Marin Headlands. The Bobcat – Miwok loop was the first of three courses we were planning to do over the weekend.


Blue-eyed grass along the Bobcat Trail in the Marin Headlands.
This course was an approximately six mile “after work” loop around the Gerbode Valley, with an elevation gain/loss of a little over 1000 ft. My legs were still a little tired from recent runs and I was happy to be doing the loop in the easier counterclockwise direction — up Bobcat and down Miwok. Except for a short segment of single track around the east side of an FAA beacon, the course is entirely on dirt roads. Bobcat sightings are relatively common on this circuit, and we hoped we might spot one.

In the city it was windy and cool, and I had grabbed a long-sleeve shirt for the run. But short sleeves would have been the better call. Here there was almost no wind, and the south facing valley was surprisingly warm — a hint of the record-breaking weather to come. Skies were mostly clear, and views extended south to the city, east across the Bay to Mt. Diablo, and north to Mt. Tamalpais.

Here’s a NPS Marin Headlands Trail Map (PDF) and a Cesium browser View of a GPS trace of our route.

Looking to do a longer run? Numerous variations and trail link-ups are possible. The course of the Miwok 100K winds through here and continues north past Mt. Tam to Bolinas Ridge, descending to a turnaround point at Hwy 1 about 5 miles south of Olema. Cross the Shoreline Highway, and you’re in Pt. Reyes National Seashore. (Bolinas Ridge fire road continues north to Sir Francis Drake Blvd. about a mile east of Olema.)

Tomorrow the Sky Trail at Pt. Reyes… but we are going to drive there.

Malibu Creek Challenge 2009

I glanced at my watch — 5.25 miles. Clouds and fog had kept temps on the cool side for more than three-quarters of the Bulldog climb, but the sun was finally breaking through. Even though temps were down a few degrees, the long climb had still been grueling. The runner next to me was breathing heavily, and I mentally repeated my Bulldog mantra — don’t redline, don’t redline.

For many of us, that’s the problem with Bulldog — some of it is runnable and some of it isn’t. For the moment I was running, but I knew the grade well, and just ahead the fire road switchbacked right, and steepened.

I’ve been over the “I can run this hill no matter what” thing for a long time. For me, and the majority of trail runners, walking the steeps is a good thing. The little bit of time lost by walking is generally made up — and more — on other sections of the course.

Rounding a corner, the grade did steepen, and I slowed and started to walk. Taking advantage of the slow pace, I ate a Gu, took a Salt Stick cap, and gulped down some Gatorade. Another runner and I had been swapping leads up the hill, and he passed me — again. As he increased his lead, I wondered if I should be pushing a little harder.

A left turn never felt so good! A few minutes before I had reached the top of Bulldog grade, and the highest point on the course. Now gravity was on my side, and I was enjoying the downhill. There were more challenges ahead, but for now I was lost in the moment — savoring the wind in my face, the far reaching views along the rocky crest, and that wonderful feeling of being a runner.

Red Box – Bear Canyon Loop

Running in Bear Canyon.

Bear Canyon

The creek burbled a gentle song of Spring, and downstream a Canyon Wren replied. Standing near the bottom of the narrow gorge, my eyes followed the soaring trunks of a grove of alders to their canopy of new leaves — backlit and bright green in the sun.

Bright green in the sun… In my run-altered state it was one of those aha! moments. The alders are just tall enough to reach from the shadows of the canyon into the sun – and – without the water in the stream that cut the canyon, the alders could not grow to the necessary height. The pieces fit — or was it the endorphins talking?

We were in Bear Canyon, west of Mt. Wilson, about 10 miles and 15 stream crossings into a 20 mile loop. An  idyllic hike along Arroyo Seco a couple of weeks before had reminded me of this wonderfully wild trail.



Our adventure had started at Red Box, on Angeles Crest Highway. Working east down the Gabrielino Trail to the West Fork San Gabriel River, snow could be seen glistening in the morning sun on Mt. Baldy’s summit slopes. There was no snow on our trail, just warm sun, buzzing bees and blooming manzanita. Continuing down the forested river canyon, we followed the Gabrielino Trail to Valley Forge, and then ascended the winding Valley Forge Trail to Eaton Saddle on the Mt. Wilson Road.

At the Mt. Lowe fire road gate at Eaton Saddle we were greeted by yellow warning tape and an “Unsafe for Travel” sign. What had happened? Did Mueller Tunnel collapse or something? Not inclined to turn back, we continued along the road, promising ourselves that we wouldn’t do anything reckless.



Other than the tracks of heavy equipment, nothing seemed out of the ordinary as we approached the tunnel. I had forgotten that the tunnel is curved, and for a moment was concerned when I couldn’t see the exit. But a couple of strides later the arched exit burst into view. The danger was an old one — an ongoing rock slide just beyond the western exit of the tunnel. There must have been a big slide recently. At the moment it was passable, and we figured as long as we didn’t stop under the slide, we’d probably be OK.

From Markham Saddle we followed the Mt. Lowe fire road out Mt Lowe’s elongated west ridge to a single track trail that leads down to Tom Sloan Saddle. From here, the Bear Canyon Trail descends into Bear Canyon following the route of the old Tom Sloan Trail.

Down in the canyon, I was glad to see that the neo-orange plastic tape that had marked the trail in 2007 was now tattered and faded, and not easily seen. Part of the enjoyment of a remote trail is its wildness. The trail descends the canyon — it has nowhere else to go. When progress is blocked on one side of the stream, it crosses to the other side. Plastic tape isn’t needed to show the way.



After many such stream crossings, we eventually worked our way down to the confluence of Bear Creek and Arroyo Seco. Along this reach there is a fantastic series of falls, pools and cascades. Gary Gunder and I were blown away by these drops when we kayaked Arroyo Seco down to JPL in 1998.

Following the Bear Creek trail upstream, we were careful not to miss the turn where the trail climbs steeply to the Gabrielino Trail and traverses above Switzer Falls. At Switzers Picnic area we parted ways — Miklos and Krisztina headed back to their car at Clear Creek, and I continued up Arroyo Seco to Red Box. It was a incredibly scenic and enjoyable trail run.

Here’s a Google Earth image and live Cesium ion view of a GPS trace of the Red Box – Bear Canyon – Switzers Loop. According to SportTracks the length of the loop was 19.5 miles with an elevation gain/loss of around 4000 ft.
