Beautiful forget-me-nots and poppies today, along with a bunch of poison oak.

Stunning views! Went counterclockwise, and there was a bit of a biscuit burner for the last half mile.

3.5. Nice loop for when you’re short on time. The Skyline section was shaded and quiet. Wide trails.

Nice n easy! When you want a quick jaunt in a beautiful setting, but not too hard, this is your trail! Recommend using the recording app to stay on the trail as there were several splits.

Sweet little 3ish mike loop at Sibley Volcanic Preserve. Came around 6pm and the clouds/fog was rolling in thick. Some covered parts, some open, lots of uphill and downhill but not super strenuous.

Pretty crowded on a Sunday afternoon. If you’re hiking, please remember to bring a mask and wear it when passing people!

Buggy for the first mile. The next 1-1.5 miles had a narrow trail and a TON of poison oak so watch out! The top/northern rock loop was great and had great views.

Nice hike. A stretch of the trail is just a paved road. The stretches through the woods are quite peaceful.
