Los Alamos & White Rock Climbing

Camping
The best developed campground in the area is the Juniper Campground of Bandelier National Monument . It has running water but no showers or electric, and is very convenient especially to White Rock. It is closed for most of the winter.

Another option nearby is Camp May by the Pajarito Mtn. Ski Area.

Free undeveloped camping can be found west of Los Alamos and Bandelier in the Jemez. Good places to look are on the dirt roads that head north from NM-4 as you're going west from Los Alamos before you get to the Valles Caldera; and off the road to the Pajarito Ski Hill. Don't camp on National Lab or in Bandelier Monument (except at the campground).

Supplies
Good grocery stores are Smiths in Los Alamos and White Rock.
The nearest camping/climbing gear shop is in Santa Fe: Sangre de Cristo Mtn Works and REI.

Other attractions
-Bandelier National Monument hosts must-see archaelogy and a short loop hike can be completed in a couple of hours.
-The town of Los Alamos doesn't offer much of interest, although the museum documenting the history of this unique town built during WWII may intrigue those interested in history and science.
-The Valles Caldera National Preserve in the Jemez Mtns offers recreational opportunities for cross-country skiing and mountain biking, as well as the largest elk herd in the Jemez; however, access is not always simple.
-Pajarito Ski Area west of Los Alamos offers uncrowded skiing Fri-Sun, or skin up on the days it's closed.
-Mtn biking: various excellent mtn. biking trails are found near Los Alamos.

If you're in the area for a short time, and don't know anyone.. there are a couple options if you want to do some climbing but don't want to commit to a plan.

An informal toproping group loosely affiliated with the Los Alamos Mountaineers heads to a different White Rock crag and shares anchors and ropes- every Tuesday and Thursday around 5 pm from March to October. Visiting climbers and non-Mountaineering-club-members are welcome to join in. By sharing toprope anchors and ropes, you can get a lot of climbs in before dark. Just show up, bring gear if you have it, but just a harness and shoes is enough if you don't. The schedule (and directions to the crags) is posted online here:

The Dungeon: there are almost always people climbing here on workday evenings, getting a workout on the 5.12s on the Main Wall. The climbing community here is friendly and the climbs are pumpy enough that offering a belay to an out-of-towner is a great way for the locals to have an excuse to rest. If you're a visiting sport climber who can get up 5.12s, this is probably your best option.
