yes, there is; along the top north-east of the map is an unclipped part of the map (see gamefaqs, blue hell) and this is the only blue hell access point I have got to work.
when you're there ( use jetpack) you will need to fly, under all the terrain above you to Area 69 (follow gamefaqs instructions) and allow yourself to drop and become respawned in Area 69, then just feel free to browse around...
