Oursan Trail in the Fall

19 Nov

I just hiked the Oursan Trail, on the north side of Briones Reservoir, last Saturday.  This is a really nice, up-lifting hike in the fall when it’s a little cool (60’s) and you want to be in the sun.  Just make sure the trail has had time to dry out from any recent rain and isn’t too muddy.  You’ll love all the views of Briones Reservoir shimmering in the sun!

EBMUD is considering opening up some of their trails, like Oursan, to mountain bikers.  Here’s a link to a recent article in the CC Times.

Bear Creek Trail

15 Oct

Length: 4.3 miles (for entire trail)
Time:  Any amount of time up to 2 hours (depending on where you turn around)
Difficulty: Easy to Moderate.
Elevation Gain: Modest
Dogs:  Not Allowed
EBMUD Permit:  Required
Calories: 800-900 (for 90 min hike)
Highlights:  The Bear Creek Trail traverses the south side of Briones Reservoir.  It is an outstanding trail that’s forested, has beautiful water views, and minimal climbing to contend with.  You can start on the Briones Dam side or the Briones Creek side and hike as far as you’d like and turn around.
Directions to Briones Overlook Trailhead (from Orinda):  From Orinda take Camino Pablo north towards San Pablo Dam Road.  Take a right on Bear Creek Road and go a couple miles to the Briones Overlook Staging Area (on the left).  The trailhead is on the northwest corner of the parking lot.
Directions to Bear Creek Trailhead (from Lafayette):  From Lafayette take Happy Valley Road up over the hill to Bear Creek Road.  Take a right and then a quick left into the Bear Creek Staging Area.   This staging area is on the opposite side of the road from the entrance to Briones Regional Park.   The trailhead is on the creek side of the parking lot.
Special Notes:  There’s a lot of poison oak here, although the trail is well-used and generally clear.

This is really one of the best trails in the Lamorinda area.  You can start on either end and turn around whenever you feel like it.  I typically hike about 45 minutes before turning back.  There is a high point with two benches that also makes a good turnaround spot.  The other option is to use two cars and leave a car at the end you’re hiking towards.  Then you can complete the entire trail.

The trail runs between Bear Creek Road and the Briones Reservoir, along the southern slopes of the Reservoir.  The south side is much more wooded (mostly Bay Laurel) than the north side that has scattered oak trees.  Along the way there are many great views of the Briones Reservoir.

Hiking from the Bear Creek Staging Area:

Crossing Bear Creek

Crossing Bear Creek

Enter the gate on the left, cross the creek, and then you’ll arrive at an old unused paved road.  Take a right and follow the straight road/path towards the reservoir.   The open area is an old tree farm.   A dirt fire road follows the shoreline and then begins to climb and changes into a singletrack trail.

After about 1.7 miles you’ll reach a service road.  Look for posts with directional arrows that show how to stay on the Bear Creek Trail.  Soon you’ll crest at a high point with two benches.  This is a great spot for a picnic/snack before turning around.

If you continue you’ll begin to go gradually down towards the Briones Overlook staging area – near the dam.

Enter the gate on the northwest side.  You’ll begin to gradually climb and wind along the slopes of the reservoir with views out towards the dam.   Briones Dam is an earthen dam that was completed in 1964.  It is the largest of EBMUD’s five East Bay terminal reservoirs with a total capacity of 60,510 acre·ft (74,640,000 m3).

After about 30-40 minutes you’ll reach a high point with two benches that make for a good spot to have a snack and possibly turn around.   After this point you will gradually begin to descend towards Bear Creek at the far end of the reservoir.

King’s Canyon Loop

25 May

Length: 6.6 miles
Time:  2.5 hours
Difficulty: Long hike with one steep section
Elevation Gain: 643 feet
Dogs:  Allowed
EBMUD Permit:  Required
Calories: 1200
Highlights:  If you love the Lafayette Reservoir Rim Trail then you’ll love this hike.  It’s a similar degree of difficulty, but a little longer and with fewer people.  This trail leaves from the Valley Vista Staging Area, just south of Moraga, and skirts along the northern edge of Upper San Leandro Reservoir, which feels a world away from the rat race in Moraga (kidding).
Directions:  Drive to Moraga.   Take Canyon Road until you see the Valle Vista Staging Area on your left.  Park.
Trailhead:   You will see a gate and a sign-in kiosk where you enter your EBMUD permit info.  Take the trail to the left.
Special Notes:  Make sure to bring plenty of water!

This is the only trail next to the sprawling San Leandro Reservoir, which was completed back in 1926 by the East Bay Water Co.   It receives water from the San Leandro Creek, which runs adjacent to Pinehurst Road and the small town of Canyon, traveling a total of 21.7 miles along the eastern side of the Oakland and San Leandro Hills.    The creek is famous for having been the site of the first rainbow trout hatchery in the world.   There are signs about the rainbow trout along Redwood Creek in Redwood Regional Park.

Beginning of the Kings Canyon Loop

Beginning of the Kings Canyon Loop

The Kings Canyon Loop starts at the Valley Vista Staging Area.  After you go through the gate and sign in (EBMUD permit required), head down to the left towards the reservoir on the Rocky Ridge Trail.  After about a quarter mile, take the trail that veers to the left down a little hill.  This will take you through a pleasant forest of monterey pines (picture below).   It is native to three very limited areas located in Santa Cruz, Monterey Peninsula, and San Luis Obispo Counties.  When you reach a fire road, take a right, crossing the bridge over Moraga Creek, and then passing a working ranch area with horses (picture below).  After you go through a gate, you will reach a junction.  The Rocky Ridge trail goes up the hill to the left.  Continue straight or to the right along the reservoir.   This is the beginning of the Kings Canyon Trail.

The trail winds, up and down, through a forest of California bay trees and oak trees along the northern side of the Reservoir (see picture).    There are many views of the Reservoir along the way, but you’ll reach the best view after about an hour of hiking.  There is a clearing with a bench and a perfect view of the Reservoir looking south (see picture).  It’s worth a stop for a few minutes!  This is a perfect place to have a little snack or picnic lunch.  With no signs of civilization in any direction it seems a world away.

When you continue, the trail will begin to turn away from the Reservoir along an inlet.  The inlet gets marshy towards the end and is a great place to spot birds.   After a little ways you will reach a gate near Rancho Laguna Park.  This is officially the end of the Kings Canyon Trail and for the rest of the loop you will be on the Rocky Ridge Trail.   From here it’s 2.6 miles back to the parking lot.

Take the single-track trail to the left.  When you reach a tiny creek bed, the trail appears to go right and left.  Make sure to go left up the hill.   Next, you will reach a fire road that goes straight up/down the hill.  Take a left up the hill.  This is the steepest part of the hike!  Take the second right turn.   The wrong turns will say “Fire Road Closed to Public.”  On the next stretch you will see views of Moraga in the distance and then a great view towards the Valley Vista Staging Area once you emerge from the trees.   After a steep down section, you’ll reach a junction where you take a left down the hill.  Take a right at the bottom, going back to the staging area the way you came.

If you don’t have time for the whole loop, you can easily hike as far as you want on the Kings Canyon Trail and then turn around.    For instance you can turn around at 45 minutes for a 1.5 hour hike.
