We are headed to Blackrock Campground in Joshua tree after xmas for a week. Anybody have suggestions on what to do with the kids 7,12 and 14. I suppose the obvious is some hiking. Any special or spectacular trails anyone has done. I heard about the Geography trail by car or 4 wheel drive. Has anyone done that! What about stopping in Palm Springs. Any activities there. Thanks for suggestions in advance. </div></BLOCKQUOTE>
