The entrance is located at -160.02, 174.49, -379.55 in The Stonebrunt Highlands; enter the Blue/Green teleport spiral.
To get there: There is no direct connection from the zone in.Travel to the Deepwater Pavilion. Go into the Pavilion and behind the entrance staircase to -160.02, 174.49, -379.55 and then walk through the Blue/Green teleport spiral.
In the Vasty Deep Conservatory, adventurers will see where the residents of Odus studied the sea creatures and plants around them. The Conservatory is a group instance geared for groups in the 86-88 level range.
The first three named are just tank and spank, but the mobs between them can be a real pain.
Most of the mobs are single ^^ or ^^^ encounters, but they have a wide agro range and are very social. Bulb Horrows have knock back, and the gilded guardians and wisps can mez you. You should be prepared for a long fight. Alot of them are also hidden, because they blend in with the scenery. (Watch out for Ropers and mobs flying high above your head)
 the Gardener: Clear the room before engaging him. At 80, 60, 40 and 20% he spawns four ^ rippers and runs away. Kill the rippers, and then the named becomes attackable again. Keep burning him down 20%, then killing adds and you should be fine.
Delahnus the Dauntless: The dragon boss of this zone. She is on a high platform, so everyone needs to rush up to her. When you are fighting her, you must always be right under her belly. If you are not, when she flies away and comes back down, you will take very heavy damage. There is also a shell with a yellow sponge you can climb onto, that seems blocks the damage she deals when she lands. Burn her to 50% and she will fly away, leaving her chest behind. But don't worry, you will see her again in Vasty Deep: The Vestigial Cella.
