Find the Cyclone Creek trailhead about 8 miles from the U.S. 50 turnoff onto County Road 240. Park at Shavano. The hike starts up a former jeep track, which has been closed off to vehicles. The track soon becomes a faint, sketchy trail. Guidebooks may tell you that the trail switches from the east side of Cyclone Creek to the west side, but I didn't see a crossing. I stayed on the east side, occasionally losing and occasionally following a faint trail through the willow thicket bordering the creek. It was not possible to make good time through the woods there, partially because of the many deep snow banks to be crossed in late May, and partially because of the boggy conditions and bush-whacking required when I was off the trail. The trail tends to parallel the stream about 50 yards to the east.
Hike 2.5 miles to a pond at the creek's origin. Grizzly Mountain looms directly in front of you most of the way.
Choose a line directly up Grizzly Mountain's south face, for a steep but straightforward ascent. The rock is steep but fairly stable. You may find the line of least resistance leads you to join Grizzly's south or east ridge below the summit, in which case the final pitch to the summit should be obvious. Descend by the same route, unless you are continuing to another summit first.
Hiking boots (preferably waterproof), and gaiters are very helpful.
