Elephant Hill is one of my favorite trails. While many on here call it easy, (for a newb it has some pucker factor to it), it is well worth the trip IMO. While it isn't as challenging as other trails, it is VERY scenic, and fun. For people that want a little challange and a lot of scenery, it is great. Fins is fun, Gemini Bridges is Fun, Long Canyon is Fun, all fairly easy with some scenery.
Have fun. It is good you love heat because there will plenty of it that time of year out on the rocks with little to no shade. You'll love the scenery though, no matter where you go.
