there are three entrances to the lost river, one is in the northern blood kelp zone, one is in the deep grand reef ( dont suggest), and one in the bulb zone ( highly recommend). while the bulb zone entrance is the farthest to the lava zone entrance, it's the safest entrance if you,re going in with a cyclops since you're only gonna have to encounter one ghost leviathan unlike the other two where you will encounter two. I also dont suggest bringing the cyclops all the way to the lava zone, leave it in the big tree part of the lost river so lava larvas wont't stick to it and drain the power. once u get near the lava castle there's a big drop leading to the lava lakes where the primary containment facility is. GOOD LUCK
