Leave no trace. No camping.
The best way to approach the Baleine is from the upper road. There are two pathes down:
A wider and flatter path where the optimal parking space is at (44.2182, 5.2317)
A narrower and steeper path, but shorter, for which you should park the car at (44.2185, 5.2353)
There are several other parking spaces along the road if one should be occupied. For both approaches just keep left and downwards until you reach the cliff.
Park where indicated, take care of the environment, buy the local guidebook when possible (this is one of the ways you can help local route setters), clean up your shoes before climbing, don't spray beta, be polite.
Did you know that you can create an account to record, track and share your climbing ascents? Thousands of climbers are already doing this.
