Seljavegur
A useful place to start if you want a calmer street and a better chance of avoiding the most obvious premium waterfront choice.
Harpa
Harpa is one of the easiest places in Reykjavik to overspend for convenience. The right answer depends less on Harpa itself and more on what kind of visit you are making. If you want the easiest possible arrival, a garage may be worth it. If you are simply coming for a meal, an event, or a walk around the harbour area, it is worth checking whether nearby street parking gives you almost the same result for less money.
This locator uses an actual OpenStreetMap embed centered on Harpa and the surrounding streets. That makes it far more trustworthy than a hand-drawn diagram for understanding where Geirsgata, Tryggvagata, Mýrargata, Seljavegur, and Grandagarður actually sit in relation to the waterfront.
Target first: Seljavegur, Grandagardur, or the west side of Myrargata.
Avoid by default: Geirsgata and the more central east side of Tryggvagata if your goal is just a normal visit to Harpa or the harbour.
Best move: drive toward Harpa, and if you hit Geirsgata and the parking already feels too premium, continue west toward Grandi before committing.
Expected walk back: roughly 5 to 8 minutes from the better-value streets, depending on the exact spot.

A useful place to start if you want a calmer street and a better chance of avoiding the most obvious premium waterfront choice.
Slightly farther west and often easier to work with if you are willing to trade a short walk for a simpler parking decision.
Worth checking because the feel of the area starts to shift as you move away from the most expensive-looking harbour edge.
Geirsgata: the main waterfront road, where it is easy to default to a more expensive central option than you really need.
Tryggvagata, east side: more central and often less forgiving if your real goal is just to be near the harbour, not directly on top of it.
If you are arriving with bags, traveling in bad weather, or need the simplest possible drop-off-and-park experience, garage convenience is easier to justify.
If you are trying to make a concert, meeting, or scheduled event, paying for simplicity may be worth the extra cost.
If you are just visiting Harpa casually or walking the harbour, the garage often feels more necessary than it actually is.
Drive toward Harpa, and if the first obvious option is on Geirsgata, do not assume you have to park there. Keep going west toward Grandi first. Around Harpa, the difference between "easy enough" and "overpaying for convenience" is often only a few minutes of walking.
