Next Meetup

Big Horn (8,441’) & Ontario Peaks (8,696')
**IMPORTANT NOTE: Group size is limited and leader approval is required to participate in this hike! Because of that, the actual start/endtime and trailhead location are NOT posted here! Please sign up on the Sierra Club's 20s & 30s section website (, then click on the event with the same name on the calendar) AND email me (Tianhe) at [masked] with your recent conditioning and hiking experience for complete information! Join the 20s & 30s Section of the Sierra Club for a moderately paced hike to Bighorn Peak and Ontario Peak (the second highest peak in the San Gabriels!) We will make our way to Icehouse Saddle, then Kelly Camp via the Timber Mountain route, where we will stop for a snack break and catch our breath from all the huffing and puffing we will be doing! We’ll then make our way to Bighorn Peak and tag our first peak before backtracking to the Ontario Peak Trail and reaching the tiny summit of Ontario Peak. We will stop to enjoy lunch while taking in the scenic views before returning the same way. This is a moderately paced, yet strenuous climb and participants should be well conditioned and prepared to hike to 8,696’. Total gain will be around 3,698’ and total distance is approximately 14 miles. Please bring layers of clothing as the summits may be cooler and windy. Hiking boots/lugsole shoes, proper attire, lunch/snacks, and at least 2-3 liters of water are required. Hat/sunglasses/sunscreen and trekking poles are encouraged. Equipment will be checked at trailhead and unprepared hikers will be turned away. Heavy precipitation and Red Flag Warning cancel.

What we're about

We are a group of 20- and 30-somethings interested in meeting new friends in the greater L.A. area while enjoying the outdoors through hiking, camping, backpacking, beach-combing, playing volleyball and other fun experiences.

We like to have fun, but we also want to stay safe. For that reason, each hike is reviewed by our organization before posting to make sure at least two qualified volunteer leaders trained in CPR and basic First Aid are involved, and we ask that all hikers stay between the leaders so that no one is left behind or goes the wrong way.

Check us out at We're also on Facebook ( ), Twitter (@SC20s30s), and Instagram (@sc20s30s).
