We have been to the NP many times with jeeps as well as quads...it is a very very rough road and you need to be careful....I have been the driver as well as passenger and it is harrowing either way....and the last time we went, which was about 2 years ago seemed worse than any of the previous times....
If you plan on going, yes...check tires, yes, check spare, use 4wd, and remember this....if you have a flat and can't get out, especially with a quad....the rental agencies will not come and get you out....YOU have to find you own way out, with the vehicle.....not trying to scare you, but want you to be aware.....
we helped some folks traveling in a jeep one year to change their tire, got stuck on a sharp rock and tire blew..
Boca Catalina, Baby beach, the lighthouse at sunrise & Pure beach
We've driven to the Natural Pool several times but the last time we did the jeep just stopped...no engine lights went off....nothing...walk out ? have the jeep towed ? holy smokes....or do what i did ...say some not very nice words slam the hood shut & try to start it again...LOL well guess what ...the jeep started we got out no problem and never drove ourselves back ....De Palm tours will do a private tour ...they drive...they bring snacks & water for the trip...we did 4 hours to where we wanted to go ... no worries for us ................Diane
