Hi Kram,
Do you mean heading from Akumo's cave to Sonte's? As far as I can remember there is no cavern before this point. Here are instructions for this part of the game:
Meeting with Sonté
Akumo’s Cave
The scene involves Magdi as well as clearing up the identity of the "Snow Monsters". Akumo will tell you that you need to find Sonté. Her location will be marked on the map, which gives us our next destination.
Once you regain control, head to the left and you will find a Melodia Idol on a high ledge. Now, head back over to the right and open the chest that Akumo was talking about. Tap on the chest and Gust upward.
Inside the chest you will find the Oloua Suit. This will allow you to move around in winter without worrying about freezing. This means the end of lighting Beacons. You will also be able to walk up slippery slopes.
As soon as you are ready, leave to the right.
Oloua Village
As soon as you are out here, hit the Melodia Statue. Gust down on the drum to reach the higher platform. If you Gust down, then use a lot of Gusts to go to the left, you will reach a Melodia Idol that's just sat on a small ledge.
Go back to the right and at this point you will be shown a Glorb pool as well as a Water Glorb. Behind them, there is a camp fire. Use a Slipstream to burn both the pool and the Glorb.
Continue to the right and the path will fork. Take the upper path along the platforms. Here you will meet a couple of Fire Glorbs. Use Cold Chill on them, before heading off screen to the right.
Oloua Glen
As soon as you enter this area you will encounter a Glorb pool. Burn it down with the nearby fire. There are other Glorb Pools on the higher ledges. Burn these down too. Once all the pools and Glorbs have gone, the Oloua who is stood close by will talk to you.
He will mention something about digging down here. This can't be done yet, but remember this for later. For now, collect the Melodia Idol in the top left hand part of the Glen before leaving the way you came in.
Oloua Village
Head to the left and drop down the gap. Here you will see a Melodia Idol sat on a platform. Follow the path to the left and then downwards. Go past the Oloua and exit the screen.
Crystal Cavern
Do a big Gust over to the right to find a Melodia Idol on the ledge here. Drop down the cliff here. At the bottom you will see a switch. Stand on it and the door to the right will open. Unfortunately, as soon as you step off of the switch, the door closes. Use the Snowball Power to make a snowball. Drop the snowball onto the switch to weigh it down. Now head through the door.
There are a couple of Water Glorbs here. Use Cold Chill to freeze them until you can light the Beacon on the right. Once you have done this, you can burn them up with fire.
Light to torch to the left, then burn down the wooden gate nearby. Drop down the cliff here. At the bottom, create a snowball and smash the ice barrier to the right. Follow the ledges up here and you will see a lever on the left. This is behind an ice barrier that you can't break at the moment.
Proceed to the right and pull the lever up here. This will open the trap door to the left and allow snow to fall next to the ice barrier. Head over there and break the barrier with a snowball. You are now free to pull the lever.
This will open a door further to the left. Go through the door and deal with the Fire Glorb. Head to the left and use the drum to gain height. Up here, you can pull the lever and collect the Journal Page.
Head back down the way that you came. The lever will have opened a trap door above a switch. This will allow you to create a snowball and weigh the switch down with it. This will open the door to the right and you will be free to move onto Echo Cavern.
Echo Cavern
Go down the slope and kill the Glorbs at the bottom. There is a closed door on the right. As the camera pans out you will see a switch behind the door.
Create a snowball and weigh the switch down with it. Now pass through the door.
Make another snowball and break the ice barrier on the right with it. Follow the ledges upwards, then break the two ice barriers on the higher platforms using more snowballs. Gust across the gap and you will come to another switch. Hold it down with a snowball. This will light a lantern further back in the area.
Quickly get down to the lantern and light the torch on the left. Now, burn the wooden gate with the fire. This will reveal a Rock and a Melodia Idol.
Place the Rock on the switch just to the left. This will open the door. Now, use a Slipstream to light the torch behind the door.
Once you have done this, go through the door. Break the ice gate using the fire. Now head to the left. Follow the path down and use the first Melodia Statue in ages.
Go down the slope and you will see a lot of Fire Glorbs. Use Vortex on one of them and shoot it at the wooden barrier. This should burn it down, allowing you to leave Echo Cavern.
The Falls
You will now be back at The Falls. Break the ice with the fire. Follow the platforms up and if you didn't already get them, you can get a Melodia Idol on the right and the third Journal Page from the left. Once you are at the top of these platforms, you will be at the top-most area of The Falls.
Up here, head to the right before dropping down the cliff. Keep heading down until you reach a bridge of the right hand side. Burn up the Water Glorbs, and then head over the bridge. You will see a Melodia Idol on the way over. You can't get this yet, but don't forget about it, because there are two very close together. For now, head off screen to the right.
Green Lake
Head to the right and light the Beacon here. Collect the Journal Page from the raised platform on the left. Use fire to take out the Water Glorbs. Next, make your way over the platforms and use a Slipstream to burn up the wooden gate.
Head to the right and you will need to drop down here. Use Cold Chill on the Fire Glorbs. As you proceed to the right, you may see a Scorpio emerge out of the ground. The best thing to do here is just avoid it. Gust over it and follow the ledges upwards.
There's a switch here. Weigh it down with a snowball and this will open up a door below. Head through the door and as you do, you should collect a Melodia Idol.
Once through the door, light the nearby Beacon. Use it to light the torch on the upper path. From this torch you can light another and from that you can burn down a wooden gate on the left. You can now go back to the lower path and use the Melodia Statue. Head off screen to the right.
Sonté’s Cave
Head to the right and listen to what Enril says about the bell. First of all, you should collect the Melodia Idol. Now, create a snowball and smash it into the bell. This will wake up Sonté.
The conversation with Sonté will result in you being able to change the season from summer to winter and back again. However, before you can do this, you will have to fix the clanger in the bell, which you broke with the snowball.
For now, Sonté will change the season to summer and you must find a way of fixing the bell clanger. Smith can do this for you in Summerfalls Village, so you should head back there. Go back into Green Lake.
