this.
i 4x4 on the beach several times a week (fishing) and there are some supplies that will help you in the event you get stuck:
-shovel (bought a mini, non collapsable shovel at HFreight for 5 bucks)
-jack (stock jack should be fine, make sure you can access it and use it)
-jacking board ( the thicker, the better; an 18" piece of 2x12 is what i use)
-tire pressure gauge (light up ones are a plus in case it gets dark)
-coiled air hose w/ tire chuck (if you air down and need to air back up, some places have hose hookups)
whatever you do, DONT pull in head first towards the water. park perpendicular, you won't have a problem getting out that way.
take your car keys and clip them via carabiner or something similar on the OUTSIDE of your vehicle. In the event you lock them inside, and don't know the code/keypad access doesn't work (like mine
) you won't be screwed
KEEP YOUR WINDOWS CLOSED!!!
i cannot tell you how annoying it is to wipe your dash clean to find it covered in dust and salt and potentially have it scratch the dash pad or door trim.
goodluck and keep it in 4x4 HIGH, as sand doesn't require much torque but instead surface area/momentum
