No special rules, but don't leave any trash on the arch and/or in the water.
Driving through Santanyi to reach Cala Santanyi and follow sign to Es pontas. You will find the parking just before on the right, you are not allowed to drive further. (see map)
From the parking follow the sign and pass the Escultura Equilibrio to arrive in front of Es Pontas. From there go down far right to reach sea level. With good conditions you can walk with your feet in the water to come back below the point of view. You will need to swim or inflate a boat to reach the arch. Be careful of hidden rock. The best exit is on the left ledge if front of Es pontas route.
