Gulpin can be found on Route 110, but it's rare.
level 26
Mystery Zone
To catch the Pokemon GULPIN, you need to fy (or walk!) to the Great Marsh. Then in area 6, there is a patch of swamp that measures 4 by 4 tiles (the tiles are located in a corner of trees, near the "Area 6" sign.) Walk around these tiles until you find GULPIN! P.S:I have 16 GULPIN's!!!
In Pokémon Ruby, Gulpin evolves at Level 26 and it evolves into a Swalot.

Yes, you can. Evolve your Gulpin at Lv. 26 and you'll have yourself a Swalot.
That guy was wrong if onPokemon platinum the only way to get gulpin is in Pastoria city's safari area but before u go in the area go up stairs and save your game. Look through the binoculars and if you don't see gulpin anywhere turn of and try again when you see gulpin memorise where the Pokemon is go there and catch it. You will need a national Dex to see it. Another way to get it is migrate. If you have a game such as ruby Sapphire Emerald migrat it from there and there you have it. If you want to evolve Gulpin into Swalot lv it to lv25
