Standing on the Coach House Terrace, you'll notice an elegant arabesque-style entrance known as the Monumental Gate. Pass through it and continue straight ahead. Soon, you'll reach the Iron Gate and enter a tunnel. As you walk through, take a moment to admire the beautiful view. At the end of the tunnel, a member of the palace staff will check your entrance ticket to verify your designated visiting time slot. Once your ticket has been validated, follow the narrow stairway leading up to Triton's Courtyard (No. 144 in the official guide). When you reach the courtyard, turn right to discover one of Pena Palace's most remarkable features: the magnificent Triton Gate.
