I think the conditions are still questionable for an ascent of San J without ice axe and crampons.
The Devils Slide Trail is much lower, and I would think it's passable now,
but I'd call the
USFS (not State Park) ranger station if I were you and ask for latest conditions (unless someone posts something definitive here). In all cases, if you get to icy stuff and even a short fall might get you hurt, turn around and go somewhere else. You need to deal with the rangers anyway since you've got to get a permit to do the hike.
If the DST were undoable, the lower, S facing
Deer Springs Trail should be open. It's roughly 14 miles RT to
Wellman's Divide, most of it south facing and therefore clear. Actually, make sure you bring water since it will be sunny. There should be water available at Strawberry Cienega and possibly in the Willow Creek drainage.
If you do go up the DST, there are a lot of nice areas that you can access without going to SJ Peak.
-The view from the
Wellman's divide area is very nice, ~10.5 mi. RT.
-You can take a nice long
loop around Skunk Cabbage Meadow, including Chinquapin Flat.
-You can take a side trip to
Tahquitz Peak. The north side of Tahquitz will probably have some snow. If it's icy, I'd bail out and go through little Tahquitz and Tahquitz valleys.
Another alternative to the DST that should be relatively snow free is to do
Tahquitz Peak via the S ridge trail, 8 mi RT. It's pretty exposed for most of the route, and it should be pretty snow free, although as you approach the top, you may run into snow. If it's icy, that's your turn around point. There's a fire lookout on top. It's fun to sit on the deck of the fire look out and eat lunch while taking in the view. By the way, there's a reason they put the look out on this peak. Pretty good views as I recall.
