Pokémon Sun and Moon - Mount Hokulani Observatory, Sophocles' Trial, Electrium Z, Steelium Z

Having finished up with Malie Garden and Route 10, it's time to hop on board the Exeggutor Express and head up the mountain.

Mount Hokulani, and its Hokulani Observatory, is the destination of your first Trial on Ula'Ula Island, where you'll meet both the old Captain, Molayne, and the new Captain Sophocles on your way to earning not one, but two Z Crystals, in Electrium Z and Steelium Z.

Hokulani Observatory, Sophocles' Trial, Steelium Z and Electrium Z

Up top on Mount Hokulani, Professor Kukui takes a moment to point out Ula'Ula's other mountain and the highest peak in Alola, Mount Lanakila. There, he tells you, is where they hope to host Alola's very own Pokémon League! In fact it's under construction now, as Kukui is only just revealing his big plans for the future of the islands. Neat!

Over at the Observatory entrance, you'll meet a chap called Molayne, who seems to be the old Captain based here at Hokulani. He fancies a battle, so take him on and, if successful, you'll earn yourself the Steel-type Z Crystal Steelium Z.

Quickly heal up, and then it's onto the Trial proper inside the building. Head into the Observatory and, in a back room filled with all kinds of strange instruments and technology, you'll discover Sophocles. Talking to him you'll discover he actually created a device to summon his Totem Pokémon, but in fact when used it simply locks you in and shuts off the power.

Your trial, then, involves answering a series of sound-based security questions to get the power back on - which is periodically interrupted by some wild Pokémon, too. We've popped the answers in a table on the right.

Once you answer each one correctly, Totem Vikavolt appears! Defeat it to beat the Trial and earn yourself Electrium Z. Afterwards, you're also given Professor Kukui's Mask, to deliver to him back in Malie Garden - it looks an awful lot like the Masked Royal's mask though... how bizarre!

Mount Hokulani - the route down

To head back down the mountain, you can eithe hitch another lift on the bus, or go down by foot, through a route of trainers. There are some good items and very rare Pokémon available here, so we recommend you take the hike!

The road only gets you about halfway down Hokulani Mountain itself, before you need to take the bus for the rest of the way. There's a photo spot off to the left about halfway down, at the back of a large platform of long grass, and a trainer at the top who'll fight you only after defeating everyone on the route. Other than that, it's a relatively quick downhill stroll!
