Hello members! This is my first time planning a back country, overnight trip so I wanted to go somewhere not too far, just one night with my nephews and I, I've read a lot of the forum posts on what gear to take and what not but now as where to go....I did some research but I'd like to go somewhere within 1-1.5hr drive of riverside CA, I was thinking big bear but I wanted to know if anyone recommended anywhere else? And if big bear what are some good moderate-difficult trails? We'd like to do some fishing, or at least be close to a stream or lake. I'd like to do 18-22 miles round trip, probably early-mid September this year. I've done plenty of one day outings 11 mile+ round trip but I want to keep it basic since some of my nephews haven't gone more that 7-8 mile on difficult rated trails. (All 16 years old+)

Thanks, any advice would be appreciated!
