Right by the epic cliffs along the southern coast of Reykjanes is this cute little lighthouse. This area is really interesting and fun to explore with a lot of seabirds, epic cliffs and even a waterfall that runs straight into the ocean during the wet seasons.
The hike from the parking lot takes around 25 minutes each way (1,6km / 1 mile) and has good views along the way.
QUICK NOTES:
What it is: A small lighthouse by epic cliffs in Reykjanes
Best season: Summer/fall (aim for rainy days so you'll have a higher chance of seeing the waterfall there)
Best time of day: Any (but light at sunset is incredible)
Nice to know: If it has been raining, you can hike a little bit further east and find a waterfall running straight into the ocean.
