I will assume you meant forgotten places that are usually free.
You listed two, Lizard City and Medusa Tower.
At level 200 as RP you can also start going to other forgotten places such as:
-Glooth Tower: Start by using walls for protection until you are confident to use corners (6 monsters on you) and on and on. This is a bit hard at this level so you might not profit at first, but try it out with great spirit potions and prismatic ring and see how good you are doing.
-Draken Walls middle floors, +2 and +3: Usually people hunt +4, +5 and +6 at the towers but +3 has easier monsters and is good for a level 200 to start, and it is always free. If no one is at +4 you can take it too! This will help you unlock charms to come at higher levels and take on the upper floors with ease.
-Grimvale -4: You could already hunt at earlier levels but Emberwing just makes it better.
-Vengoth Castle: No one hunts there anymore, the place isn't great but it is always free and quite fun / old school feeling.
There are many more areas that are usually used by lower levels but that you can still hunt. Things like Oramond minos north-east spawn, Edron vampires or if you prefer profit hunts, Roshamuul Bridge, Ghastly Dragons or Darashia Skeletons with walls.
