Despite all your prep work and proper driving style, the Jeep is stuck. Here are the steps you should follow to get yourself out.
Shovel: Often times, just simply shoveling the sand around the wheels is enough to regain traction and get you moving again.
Recovery strap: Although it might look similar to a “tow strap” a recovery strap has elasticity to build up momentum when pulled. A tow strap has no elasticity and is used to pull the free-rolling vehicle back onto the road or a safer location for repair. Assuming there is another vehicle nearby to help pull you out, properly attach the strap to an appropriate anchoring point such as D-Rings on after market bumpers or the tow hooks on the factory bumper. Never attach a recovery strap to the Jeep’s axle or looped around the bumper. Keep in mind most tow straps come with steel hooks. It's better to find a tow strap with looped ends to avoid any injury or damage while towing.
Self-recovery: In the event there’s no other vehicle and you have a winch, you can try two self-recovery methods. The first is through the use of a sand or land anchor. This handy tool looks like a shovel blade with a bent L. The end of the L faces the Jeep, and attaching the winch cable to the end of the bar anchors it to the Jeep. As you engage the winch, the blade will dig into the sand and pull the Jeep. The more it’s pulled the deeper it will dig into the sand and provide more of an anchoring point for recovery. The second method is an alternative to the sand anchor. Digging a deep hole, attach your winch cable to your spare tire, cover it with sand, and initiate the recovery by engaging the winch. This last method is obviously more labor intensive, so if you plan on off-roading on the beach alone often, it’s good to invest in an anchor.
