Sonic Frontiers stage 1-7 is one of the many first stages of the game that you can find among the Kronos Islands.
However, unlike other stages in Sonic Frontiers that are easily accessible on foot, Stages 1-7 are on an island south of the landmass and seem inaccessible.
There’s a little puzzle to reach them – which not only allows you to reach stage 1-7but several other elements at the same time.
How to Reach Stages 1-7 in Sonic Frontiers
As you explore and unlock challenges, you gradually begin to unlock more of the map. This will soon include stage 1-7 – which is located on an island south of the Kronos Island area.
However, it is apparently inaccessible – with no rails or platforms leading to the island.
To reach step 1-7, you need to find a puzzle switch on the cliffs to the east. It will have three nearby poles, which you need to interact with first, creating a tether between them.
Do it left to right or right to left – as long as you do the middle pole second – recreating the pattern that is on the switch.
Now press the puzzle switch. This will create a rail that you can use to cross the leftmost island.
Once there, you have another one of those puzzles. This one is easier – only the two poles need to be connected. Do this, then activate the switch, to create another rail – this time from the previous cliff to the island we’re aiming for.
Go back and cross, and you can now access stages 1-7.
Also here are several fishing tokens, a side quest, and a switch that creates a source for you to return to the mainland.
Good luck getting all the Stage Keys!
