Hi there. In order to reach the Meteor Falls 1F 2R map, you'll need to first access the Meteor Falls basement floor. Here's a post showing how to get there.
Once you've found the area with the pitfall and fallen into it, you should be at the basement end of the Meteor Falls 1F 1R map.
Take the ladder into the next map, Meteor Falls B1F 1R. Make your way up towards the ladder at the top right, near Battle Girl Tess.
You should arrive at Meteor Falls 1F 2R afterwards.
