When in flow, Last Chance Falls is arguably the most dramatic waterfall in the Ventana Wilderness. The falls flows over an overhanging precipice with a 120 foot free fall with a large cavern behind the falls. A natural amphitheater of cliffs surrounds the falls. The ephemeral nature of Last Chance Falls perhaps makes it more special and requires planning, or more accurately, waiting, for the ideal conditions. The drainage upstream of the falls, the headwaters of the South Fork Santa Lucia Creek, is relatively small and in a climatologically dry part of the range. However, in early February an atmospheric river impacted the central coast interrupting months of virtually dry weather. Rainfall amounts were healthy over the Ventana Wilderness but particularly over the Santa Lucia Creek drainage, which is typically a drier region on the east side of the range but received impressive rainfall totals of around ~6 inches in just a couple days. This provided a great opportunity to see Last Chance Falls in flow. By “in flow” I mean a solid stream of water from the top to the base of the falls. The falls becomes merely a trickle in summer and fall and otherwise has no flow or low flow for all but a handful days of the year immediately following heavy rains. This is a quintessential flashy waterfall, and especially flashy after an atmospheric river event during an unprecedented multi-year drought. GPS route here.
A great viewpoint of the falls is located on the Santa Lucia Trail as it switchbacks out of the Canyon. One can also travel cross country following the South Fork Santa Lucia Creek upstream to immediately underneath the falls with exploration of the pool and cavern. The setting of the falls is magical. Visiting Last Chance Falls also provides an opportunity to explore the immensely scenic Santa Lucia Creek gorge, including the 35 ft Jeff Falls, which is picturesque, particularly in the high flow we experienced. Next to Jeff Falls is Mutt Falls, a tall but skinny falls from a side tributary. Both Jeff and Mutt Falls are visible at the same time and are aptly named by Jack Glendening (http://bigsurtrailmap.net/ creator) after the historically popular comic strip with similarly proportioned characters. Dr. Jack also named Last Chance Falls after the the camp downstream in beautiful meadows of the same name. In my opinion, Last Chance is a great name for this ephemeral falls. Jeff Falls is much less flashy than Last Chance Falls since its water source includes the main stem of Santa Lucia Creek which drains a region several times the size of the South Fork Santa Lucia Creek alone. Thus, if Jeff Falls is running low, Last Chance Falls may be a trickle or bone dry.
As a shorthand, I’ve determined that flow of 250cfs or greater on the Arroyo Seco River will yield a an “in flow” Last Chance Falls but to really bring out the beauty of the falls it seem flow of 500cfs or greater is needed on the Arroyo Seco. The Santa Lucia Creek gorge entails several crossings of Santa Lucia Creek which was running high (Arroyo Seco was ~550 cfs on this day). If the flow was much higher the lower part of the Santa Lucia trail would be impassable. Thus, it would not be advisable to access Last Chance Falls via the Santa Lucia Creek gorge if at peak flow immediately after big rainfall events. Instead, use the Arroyo Seco-Indians Road and drop down into the drainage after the South Fork Santa Lucia Creek has branched off. The Arroyo Seco-Indians Road has some awesome views of the Arroyo Seco canyon and the interior of the Ventana Wilderness. Another great addition is the ridge immediately above the Arroyo Seco campground. A use path runs across the spine of this ridge and includes some fantastic views of the Arroyo Seco region.
