Starting the Castle Creek Road climb you'll ascend into dramatic Northern California scenery, with incredible close-up views of Castle Crags' granite spires and often glimpses of majestic Mount Shasta. Be prepared for varied gradients; while the overall average might be moderate, expect some demanding pitches well over 10%, hitting ramps of 15-20% in short, tough sections that will require significant effort.

The Mount Shasta City Park is a small, attractive urban park in the town of Mount Shasta. There are walking trails, benches, and Big Springs, the headwaters of the Sacramento River that flow through the park. This is a great place to spend the afternoon exploring or to tack on to the nearby Spring Hill if you're looking to add a few extra miles to your hike.

Great views, be careful on the way down, lots of big potholes and loose gravel.

Half-mile trail to the mouth of Hedge creek into the Sacramento River. About halfway is the beautiful waterfall. Easy, wide trail. Water fountain at the gazebo near the start.

Attractive waterfall in just a half-mile distance from the trailhead, just before it flows into the Sacramento River. Best at spring/early summer flow, it thins out later in the season. Cool Cave behind the falls.

Large lake east of the Trinity Alps, with excellent loop trail and surprisingly decent water levels so far.

A bridge spans over the rushing Sacramento River that flows into Dunsmuir. There is also a parking lot next to the bridge at Soda Creek Road: a good spot to get picked up for a ride into the towns of Dunsmuir, Mount Shasta or Castella.

The mighty Sacramento River is still rather small this far north, but from south of Dunsmuir it can be rafted in high spring flow conditions.
