Catch Snorlax on the bridge

In Pokemon Let’s Go, is it possible to catch the Snorlax on the bridge prior to beating the Elite 4? I keep trying to catch him but he keeps running away.


Solution 1:

You can catch that Snorlax much earlier than defeating the Elite 4. I caught it soon after I obtained the Poke Flute. I needed to use berries and ultra balls, and I was able to catch it after several throws.
