F:NV was a lot better about this IMO. Right after leaving the docs place you can head to the strip in a straight line, and it will take you through a route with some of the most powerful creatures, like giant radscorpions and cazadors, and if you somehow manage to get past them there is a mining site filled with deathclaws! There are in game warning signs telling you to not take the route but you are totally free to ignore them.
