Everlook is a goblin city in Winterspring. Most players get to Winterspring via the Timbermaw Hold tunnels from northern Felwood. The tunnels split into a "Y" from Felwood, so you want to take the northeastern direction. By default the Timbermaw furbolgs are hostile, so unless you want to fight your way through, you should do some reputation quests in Felwood to at least get to unfriendly with them. That way you can travel through the tunnel and they will only attack you if you attack them.
