Mt. Shasta Climbs

Distance:  c. 35 miles, two out-and-backs
Elevation gain: c. 4800 ft

These two climbs and several other good rides in Siskiyou County are mapped at www.CycleSiskiyou.com.

This is the prime 35 miles of the Shasta Summit Century.  It consists of two perfect out-and-back climbs through typical NorCal piney forest, and nothing else.  The pitches are never intimidating, and both descents are just dreamy.

Begin at the intersection of W. A. Barr Road and Castle Lake Scenic Drive.  Ride up W. A. Barr Road as long as you wish to (hence the vagueness in the distance and elevation gain figures above—I just picked a random spot along the road when I mapped).  If you climb for 13 miles (19.5 miles from your parked car), you get to a summit and an intersection at the Gumboot Trailhead (there’s a large sign.  Gumboot Lake, no relation, is actually briefly visible off to your L as you near the summit).

You can actually keep riding past the summit (see Added Miles), but Barr is best in its first half, which is all paralleling a charming, tumbling, rocky stream (in fact, the headwaters of the Sacramento River) at a consistently mellow pitch.  When it leaves the stream, it gets a bit steeper (though never steep), a bit narrower, a bit straighter, a bit rougher, and a bit less interesting.  As long as you’re riding in the creek canyon, the terrain is creek boulders on one side and rock cuts on the other, very pretty in its way, and completely different from our other climb, Castle Lake Road, which is wooded, then open with vistas.  Since Barr gets less appealing as it goes up, you can turn around as soon as you sense  the magic is gone and enjoy the perfect descent back to the car.

Back at the car, ride up Castle Lake Scenic Drive until the roads ends at Castle Lake (7 miles one way).   As with Barr, the climbing never gets demanding, with pitches varying from mellow to moderate, but, as I say, the feeling here is very different from Barr: this road is more thickly wooded and with big, grand views of Mt. Shasta near the end of the climb.  Castle Lake is a lovely little natural lake with a campground and picnic tables by the water, a perfect place for dallying and cooling your toes. When your inner peace is topped up, turn around and enjoy the descent, even better than Barr, back to your car.  If you’re only going to do one of the two climbs, do this one.

Of course you could do this as a part of the organized century, and that way you’d get fed.  But two bad things would happen: 1) you’d have to ride up the Mt. Shasta road  (officially the Everitt Memorial Highway), a 13-mile, essentially straight climb of unvarying pitch and bland scenery that’s laborious and boring.   Then on the descent you just sit on the bike at 40 mph and read a book.  Some people love that sort of thing.   I don’t.  2) The descents of Barr and Castle Rds. would be thronged with cyclists riding up, chatting and weaving all over the road, and your descending line and your peace of mind would be constantly interfered with.   It’s worse than car traffic.  At least cars usually stay on their side of the road.

Adding miles: There’s a lot of good riding around this ride.  The part of the Sierra Summit Century route we haven’t discussed, which runs on back roads north through the valley they share with Highway 5, is perfectly pleasant mountain valley rollers past meadows, lakes, and farms, with frequent grand views of Mt. Shasta.  There are several alternate routes, but a good one is, begin at the intersection of N. Old Stage Road and Hatchery Road; ride north on Old Stage until it ends (it does some turning and jogging); go R under Hwy 5 and take the immediate R onto Edgewood (the large road sign reads “Edgewood” and points L—go R anyway); when Edgewood ends, go L onto N. Weed (don’t go under Hwy 5) and follow N. Weed through the town of Weed and out the other side, going under Hwy 5, and take the immediate R onto College; when College deadends at N. Old Stage Road, go L on Old Stage and return to your car (about 30 miles).

If you keep riding south on Old Stage Rd, then go L on Mott, and straight onto Dunsmuir Ave., you can ride all the way to Dunsmuir, the next town to the south, which would give you about 50 miles of mellow mountain valley rollers.  Past Dunsmuir the route gets difficult to follow and generally unrewarding.

There’s also a climb at the northern end of the valley loop, up Stewart Springs Rd., on what’s known as the Super-Century route, for those who want 10 more miles of challenging climbing.  I’ve heard it’s good.

The climb up W. A. Barr Road is part of a 50-mile loop ridden by the Castle Crags Century.  At the Gumboot intersection, stay on Barr (the obvious main road) as it turns L (south), crosses the obvious summit, and begins to descend.  It will go up and down along the sidehill, with fine vistas along the way, until it deadends into Ramshorn Rd. (totally unmarked).  Go L on Ramshorn (R turns to dirt instantly) and do a steep, rough descent to Castle Crags State Park and the intersection with Hwy 5 (by which time the road has changed its name to Castle Creek Rd.); then work your way back to Mt. Shasta via frontage roads.  This last leg is continuously confusing and  poorly signed, so carry a thoroughly detailed route sheet with you.  It’s not a loop I recommend—the big descent is so rough you suffer it rather than ride it, and the leg from Castle Crags to home is grindingly, lengthily uphill.  You can find details of the route on the Castle Crags Century website or on www.CycleSiskiyou.com.  Bring your legs—I recorded 55 miles and 6700 ft of vert on the loop.

Afterthoughts: From your parking spot, there is water a short ride down Barr in the other direction.  At the corner of W. A. Barr and Siskiyou Lake Blvd, you will see tennis courts, and there are water fountains along the fence perimeter.  I don’t know if there’s water at Castle Lake.
