Pokemon Legends: Z-A Larvitar Location Early, How to Get Alpha Larvitar and Tyranitar

Players looking for Pokemon Legends: Z-A larvitar early in the game can find it after unlocking the Roto Glide ability around main story mission 10 to 15. This method in the Pokemon Legends: Z-A Guide leads to a spot with potential for an alpha version that evolves into a massive Tyranitar. The other way to obtain one comes much later in the storyline.
Head to Wild Zone 2 and move west toward the park area. On the north side of that park, climb the ladder to reach the upper level. From there, turn left and keep going left while following the buildings southward until a gap appears.
Glide across that gap to land on the next building. Move forward and then left to reach the Pokemon Legends: Z-A larvitar locations where the spawn point sits. If no Larvitar appears, drop down to find a nearby bench and rest until day or night to reset the area.
Alpha Larvitar Location on Map:

Climb back up and check the spot again, repeating the process as needed until a Larvitar shows up. For Pokemon Legends: Z-A alpha larvitar, continue resting at the bench and checking repeatedly since alphas spawn randomly in that location. The alpha version starts at level 32 while regular ones are around level 22.
Once caught, evolving it leads to Pokemon Legends: Z-A alpha tyranitar with its large size from the alpha trait.
