Hi there!
1) I am trying to plan a visit to the Yosemite in the beginning of march. It is obviously a bit last moment, due to hesitations and uncertainty concerning the possibility of such a visit! Now I am very excited, but a bit scared of the "first one/first served" at camp 4. What happened if all the spots are occupied? Is there a way to camp a little further? (I didn't find any reservation spot available in the other). Do you have any idea if the camps are usually crowded in this period of time?
2) We are planning to hike for three days, doing only day hikes from the Yosemite valley. Would you strongly advise to get some traction devices? What hikes would recommend?
Cheers!
