Hike 2015.083 -- North Etiwanda Preserve, Rancho Cucamonga, CA
North Etiwanda Preserve as at the north end of Day Creek Blvd. From I-210 (Foothill Freeway), just west of I-15, take the Day Creek Blvd exit and head north approximately 2 1/2 miles.
There are no restroom facilities at the trailhead. There is a pit toilet approximately one mile along the loop trail if you start counterclockwise, or two miles along the way if you go clockwise.
Shortly after the end of the pavement, there are two locked gates, one to the north and one to the west. Those are the two ends of the 3.5 mile loop that traverses the Preserve. Within the preserve are several exhibits that interpret the historically significant remains in the Preserve.
To get to the waterfall, head around the north gate. After a bit more than one mile (distance markers are on the loop at 1/4 mile intervals), you'll reach a multi-directional split. The loop trails would head west. There's a picnic area, a bit to the east. On the other hand, if you go straight, you'll be on the path to the waterfall.
There's a disappointing but not surprising quantity of graffiti down there.
Return to the main trail. Once there, continue further up-canyon. In another 1/8 of a mile or so, you'll reach the top of a set of waterfalls. There'a narrow canyon that links the two sets of waterfalls, which is pretty impossible from the safely-accessible top or bottom.
From what I have seen, it's about 3.5 miles roundtrip if you go from the parking area to the falls and back.
The trail then heads somewhat to the east, then south, and includes an overlook of what is described as a marsh. This whole area looked relatively well-covered in foliage for the area, which is probably due to a high water table that made this place a target for early water development in San Bernardino County.
Somewhere between 4.5 and 5 miles total for the hike. Moderate climb on the way to the falls, then largely level, then a descent. The weather on my hiking day was comfortable. This area can obviously get hotter and windier than it was, in which case you'll want to make sure to have lots of water.
