Will do, My GPS program got wiped so I will have to pull them up on Google Earth.
There are some Great trails near Lake Mead.
If you don't mind the Drive I really Recommend Christmas Tree Pass near Laughlin (90min south of Vegas)
I am heading up to Zion tomorrow for a week soon as I get back I'll dig them up!
Most of the tails in Lake mead have been destroyed by NPS to cut back on transients living out there (a REAL problem around Boxcar Cove) but further back along North Shore Rd there is some real fun and challenging Trails.
My Fav spot is on an unnamed road about 2 miles east of the road to Callville Bay. Your going to cross a wash the turn on the dirt trail to the left. Head down to the Wash and make a right (you can go left and drive under the bridge it you want, but you can't go much further than that in an E) There are tons of Trails for the E around there. Most of them are sand washes and narrows. LINK
36°12'12.43"N 114°43'58.56"W Crematorium Narrows
That is not the real name, I call it that because of the rather odd and somewhat creepy place people have set up a campfire. It is a challenging trail. You can only go so far before you have to pull about an 18 point turn around and head back. But trust me it is WELL WORTH IT.
36° 15' 50.41", -114° 28' 56.61 Boathouse cove and Cleopatra's Wash
This one is a tough trail, in fact I don't know if part of it is even passable anymore since the rain (been over a year since I have done it). If you like Hiking. I HIGHLY recommend Cleopatra's Wash. Stop at the Second campsite (if you can make it) and walk due east along the wash. it takes you to Lake Mead Via one of the best (in not THE BEST) trails in the LV area. Be aware that you will need rope for some of the water falls. Check the links for more info
If you drive past the 2nd campsite there is a riven that is a PAIN IN THE ASS for the E. I barley made it last time so use your better judgment. But if you do make it there is a beautiful cove waiting for you.
