We camped lower than the pin, at the campsites by the Hermosa Creek TH. There are 4-5 campsites here and no creek crossings involved. We were here early June for 3 nights and the creeks were high, questionable to cross with 2wd but fine for 4wd. The first creek crossing on Hermosa Park Rd isn't until 1.75 miles after the TH area, and there are plenty of awesome spots before that. The road is well maintained and there are signs at all road junctions to keep you on the right track. If you camp by the creek there is catch and release fishing for cutthroat trout, lots of people there fishing during the day. Hermosa Creek Tr is awesome for biking/hiking/running too.
