I second everything that parklover said. I'd also add some additional reasons to at least visit the Hotel Wawona:
- As the oldest, continuously operating hotel in California, it is historic and charming
- As parklover said, the food is generally very good, if a bit pricey (on Saturdays they do a BBQ on the front lawn...I've never partaken but it seems VERY popular).
- On Tuesday through Saturday nights, you absolutely must go hear Tom Bopp play piano in the lounge (times vary from season to season but he usually starts somewhere between 5&6 and plays for 3 or 4 hours). Tom is very knowledgeable about Yosemite history (especially in the Wawona area), he's a walking encyclopedia of American popular music from the late 19th through the mid-20th century and he is, generally, an extremely entertaining and funny guy. Although I don't go to Yosemite just to hear Tom, I've never gone to the Park and not seen him.
Jo Ann, if you're a waterfall junkie and are reasonably fit, don't miss Chilnuana Falls in Wawona. It provides an incredibly varied hike through all sorts of terrain, ending up 2700' up at the top of the Falls. Most of the elevation gain (except for a short section at the very beginning) is quite gradual so this is fairly easy and will show you woods, meadows, granite outcroppings, steps along a raging river and more. It's one of my favorite hikes in the lower section of the Park.
Another great one that will get you away from a lot of the crowds is the series of falls along Crane Creek as it makes its way downhill from the Foresta area and is joined by Little Crane Creek. There's an old dirt road that goes from the end of the residential area in Foresta and ultimately goes down to El Portal. Walk the first few miles and you'll encounter at least 3 spectacular (one quite large) waterfalls (I say "at least" because Crane Creek goes over a long series of cataracts through this area so exactly how you count is sometimes a bit arbitrary). Note that, except for the first one (
Foresta Falls), these are un-named falls but well worth a visit. Be sure to continue a few hundred yards beyond the 3rd waterfall (the one on Little Crane Creek) and look back across the gorge for spectacular views of Crane Creek careening down the mountain.
You mentioned that you plan to go to Nevada Falls (an
excellent choice...standing at the top of Nevada and looking down is one of my favorite places to be...
anywhere! I'm not kidding when I describe it as one of the most profoundly spiritual places I've ever encountered). Assuming you plan to take the Mist Trail in at least one direction, wear quick-dry clothes and carry a change of socks. Also, have plastic bags to wrap any electronic or other "must-stay-dry" stuff. Seriously. In June, climbing the Mist Trail is a lot like being out in a low-grade hurricane. It's very windy with an extreme amount of moisture whipping around you. Don't let that scare you...it can be a lot of fun, especially on a hot day but, as they say in the amusement parks, you WILL get wet on this ride! FWIW, I typically go up the Mist Trail, cross the Merced at the bridge near the top of Nevada Falls and then come down the JMT. In fact, one of my favorite points of contrast is going from the raging fury of the river at the top of Nevada into a normally quiet and peaceful glen in the woods very shortly after you cross the bridge (if the winter turns out to be as heavy as it appears, this won't be entirely peaceful and you may need to do some rock-hopping as parts of the trail will be under some water but the contrast is still remarkable).
Also, don't miss the dozens of ephemeral waterfalls which flow only in late Spring/early Summer. Even tiny ripples coming down the side of a rock face can give rise to stunningly beautiful outgrowths of moss, ferns and small flowers.
Do be careful, though...rocks along the rivers (and especially near waterfalls) can be VERY slippery. Stay on posted trails and you'll be fine.
I'd better stop there or you'll be wondering how you can see all of this in 4 days (answer: you can't so plan to return repeatedly for the rest of your life!
