how to get to hibat caverns?

how to get to hibat caverns in final fantasy explorers

i know its confusing how to get there because we should be able to go to hibat cavern thru hibat foothills but yeah as you already know you cant do that,

you can get to hibat cavern by going thru  Maxon ravine

 then going thru the cave in maxon rtavine 

just push thru the cave and eventually you will reach the sand filed place and then hibat caverns and in there find the objective and finish the quest
