I'm going for a visit to LA and Anaheim (first time in US) in about 3 weeks time and I was frantically looking for something significant to visit while there preferably on a day trip. I'm a nature lover and not too into tourist traps, so hate the idea of Hollywood and celebrities. I found out that the world's oldest tree resides in Methuselah Grove in the White Mountains.
I read on Wikipedia that Methuselah (the tree) is unmarked to protect it from vandals. I can understand that. But is it safe to assume that it is even in Methuselah Grove?
If I'm staying in Anaheim, how feasible is it to take a day trip out there? With public transport?
Any other suggestions on what to see, along similar lines that can be accomplished in a day on public transport?
