After doing my due diligence on TA I have a vew questions about JTNP. My girlfriend and I plan on making it a day trip this coming Saturday from our base in Palm Desert. From the park website, it looks like Cottonwood is the best place for wildflowers, so I'm thinking that will be our hike of choice; about 3 miles according to park info. Could someone out there confirm this info. Also weather is consistently showing it cooler at JTNP than Palm Springs....in the 60's this weekend. I somehow expected it to be hotter. Does it change with elevation, not sure about clothing for hiking. Finally, I collect national park posters and was wondering what visiter center would be recommended for this. Thanks in advance!
