|Route 27 (Kanto). Surf south of the bridge that leads to Route 26, then use Whirlpool to access a secluded area where TM22 lies.
TM22 SolarBeam is located on a secluded spot of land on Kanto’s Route 27. You can reach this area by using Surf and going east of New Bark Town.
But you’ll have to cross the Tohjo Falls cave to reach the Kanto side of Route 27, then continue eastward until reaching a bridge. Then you’ll have to use Whirlpool to cross over a section of water to finally reach the piece of land with the SolarBeam TM.
TM22 lies on the Kanto side of Route 27, which is only reachable by crossing Tohjo Falls from Johto.
A Pokémon that knows Surf allows you to reach Tohjo Falls from early on in the game. But the cave blocks your progress until you’ve collected all of the Johto Gym Badges, since you’ll need to climb a waterfall to progress.
So here’s what you need to climb waterfalls and to reach the SolarBeam TM:
- Get HM07 Waterfall from the ground floor of the Ice Path, accessible from Mahogany Town’s eastern exit.
- Defeat Gym Leader Clair in Blackthorn Gym so your Pokémon can use Waterfall outside of battle.
- Bring a Pokémon that can use HM06 Whirlpool.
With this, you’ll be able to cross into the east side of Route 27 and pick up SolarBeam.
Getting TM22 Solar Beam (Step-by-Step)
Step 1: Use Surf to cross the water east of New Bark Town.
Step 2: Land near the NPC and enter the cave to the northeast (Tohjo Falls).
Step 3: Use Surf and Waterfall to cross Tohjo Falls.
Start by using Surf to approach the waterfall ahead, then use Waterfall to climb it.
Then follow the water eastward and turn south at the next waterfall.
Keep going south and you’ll see the exit to the right.
Step 4: Once you’re back outside, use Surf to cross the small lake to your right.
Land on the other side and continue east through the tall grass.
Soon you’ll find yourself at a bridge. We’re almost there!
Tip: Trainers around this area have teams in the Lv.30-35 range, while the Pokémon in the tall grass are in the Lv.28-32 range.
Step 5: Walk onto the bridge going east and use Surf below the first tree you’ll see just north of the bridge. You can see this pictured below.
Step 6: Surf going down and you’ll quickly reach a whirlpool spot.
Use Whirlpool to cross into a secluded area, and then follow the path westward.
Step 7: Surf until you see a strip of land with an overworld item – this is TM22 SolarBeam.
Note: The NPC on this piece of land will want to battle. His name is Bird Keeper Jose and he uses a Lv.34 Farfetch’d.
It’s a single Pokémon, so you should be fine, but you can also skip this fight by landing up higher directly next to the TM item.
TM22 SolarBeam Details + Uses
|SolarBeam Move Details
|One turn. Launches immediately under harsh sunlight.
|10 (max. 16)
SolarBeam is the most powerful Grass-type move in Pokémon Crystal, but it comes with a major downside:
Having to charge-up the move for one turn before it can be used.
This effectively halves your damage potential over the course of two turns.
What you might want to do is combine SolarBeam with Sunny Day, which summons clear skies and bright sunlight for five turns.
The brighter sunlight weather allows your Pokémon to use Solar Beam immediately in a single turn, devastating your opponents in no time.
Tip: This strategy is especially useful against Gym Leader Misty in Cerulean City.
Ideally you’d want to teach Solar Beam to a Grass-type Pokémon with high Special Attack. Here are some of my favorite candidates:
|Evolve Weepinbell with a Leaf Stone.
|Starter (Chikorita line).
All of these Pokémon get STAB damage when launching Solar Beam, and they can all learn Sunny Day to remove the charge-up turn.
