I have a couple of friends who have been learning about and practicing ultralight backpacking. The issue is, they are a couple and for "her" benefit they typically go to places like Point Reyes or some of our state parks like Henry Coe where there are pit toilets. They've agreed to go to a no-toilet site with me this weekend, and are excited because they have not been to the sierras before.
So my question is – what is the most beautiful hike you can suggest that's within 2-3 hours of San Francisco. I am thinking Aloha Lake from Echo Lake might be nice. I also thought about the alpine lakes around Grouse Ridge, Penner Lake, Loch Leven Lakes, etc. We are all in good shape, but I doubt they want to do more than 12 miles.
Anything I haven't thought of that those who spend more time in the Western Sierras might suggest? Extra points for pit toilets and easy-to-get or not-required permits.
Thanks in advance! I really want to knock these guys socks off so they will join me more often.
