Yes! Even in the desert of Pasadena, you can find waterfalls. I decided to hike Eaton Canyon on a solo adventure over the end of spring break. Due to recent rainfall, the waterfall at Eaton Canyon was especially... waterfall-y. Other times, the waterfall and rivers are more barren. Many yellow spring blooms sprung up in the beginning stretch of the hike from the Eaton Canyon National Reserve. I really wish I took a photo of it, but just imagine surrounded by bushes of yellow flowers along both sides of the trail.
The trail head is only 4 miles away from campus and I've heard of classmates who've biked there for the hike, and then biked back to campus. It's a short hike - only about 3 miles round trip - but I started out at around 3 pm and got back around 6 pm because I took an extra leisurely pace...
For part of the trail, I wandered off main path along the narrower paths up the hills. These small paths branched in several areas and I was careful to take the paths going in the general direction of the main trail. It made me feel like a true adventurer. Eventually I made my way back to the main trail, where the sound of laughter and splashing caught my attention. Some teenagers were splashing down the river along the trail. Tempted, I went down and river hopped upstream along the river with my bare feet, stepping on the round warm boulders where I can, and letting the cool stream wash over my feet other times.
After I while, I managed to find my way back up to the trail, and proceeded to the more foresty area past a concrete bridge looming overhead. The path wound in many branches through the river, so at some points, I had to choose broad logs to walk over the water. At one point, I got stuck in the middle of one such log bridge, crouched on all fours and too scared to continue going forward. Fellow hikers found me and waded over, helping me hold my electronics as I maneuvered my way to the other side.
The waterfall was pretty, and I waded under it for a few seconds, admired the view for a while, then started my way back. Unfortunately, I was so enraptured by my phone as I got closer to civilization and got signal back that somehow I found the path getting narrower and narrower... I had accidentally gotten lost off the main trail. Fortunately, I felt relatively safe because I knew the trail intersected with the river upstream somewhere near the beginning. Unfortunately, I overshot that intersection and had to make my way up the hill a ways and finding a path back. Finally, I was able to follow the yellow (flower) road back.
