Travel Directions

First a word on road conditions and vehicle concerns:

We strongly recommend that you follow the route outlined in our maps and directions below. There are other routes that can get you to Table Mountain which may seem shorter if you are coming from the north on Hwy 2 / Hwy 97, however those roads are dirt/gravel the entire way and generally not suitable for anything other than the most adventerous 4-wheeler.

The road to Table Mountain, following our directions, is paved to within three miles of the star party site, and is gravel for the remainder of the distance. The paved road is, at times, steep and always narrow (only one lane, with turn outs for passing) so caution and careful driving is necessary.

Use special care if driving an RV, motorhome or pulling a trailer. Those in route to the 1998 star party found that due to very hot weather, many vehicles developed vapor lock problems. Be certain that your transportation is in good working order to help minimize those problems.

When leaving, be sure to use the lowest gear in your vehicle and use your brakes as little as possible to avoid overheating and loss of brakes.

Keep it in Low and use the brakes sparingly going down!
