Almost no effort on my part.
There aren't really any "good" monster maps to actually grind on, after about level 100. Like MintPanda said, Temple of Time's first map might be okay, but LHC is by far the best. You could try some PQs, but if they're boring to you, give LHC another chance. You can only do PQs a certain amount of times a day anyway.
Alternatively for Monster Park, you could solo that.
