The day was overcast for the majority of the day, but sunny at both peaks. Trail conditions were good I started my day just after 7 am and made it to the first peak/Cucamonga by 11:30 am then made over to ontario peak by 3:00 pm back to the parking lot by 5:00 pm to call it an amazing day. After taking a picture with the ontario peak my phone completely died so my full hike couldn't be tracked by my phone all in all what a day two down four left to go… I'm not sure how many miles I covered 16 is just my guess if anyone knows the exact mileage of Cucamonga peak and Ontario peaks total mileage please lmk. Doing both peaks in one day I feel very accomplished I didn't run into anyone else that did both nor did I see any other six pack challengers.
