Seljalandsfoss is a 200-foot waterfall that you can walk under. We had to pay about $5 for parking (credit card only) and it was an 1hr 45 min drive from our hotel in Reykjavik.

Recommendation: Wear rain paints or something you can get wet. Our pants and jackets were soaked.

After you exit on the other side, you can hike up another 1/4 mile and enter a cave. There you will find another waterfall that you can walk up to. You might get wet entering an exiting the cave, but it's worth it!

This semi-remote natural hot springs was recommended to us by a friend (shoutout to Connor!). It's easily accessible off the main highway, but you will drive slowly on dirt roads until a clear car park. From there, you'll hike back a half mile and cross a small stream before getting to this scenic (albeit sketchy) pool. I wouldn't call it "hot," but it's warmer than the air. There's a small room to change your clothes, so don't forget a towel (that was our big mistake). The water is filled with algae, but it overlooks a glacial stream and it was definitely a unique experience. I personally recommend jumping into the glacial water before hitting the pool so it feels warmer.

This was the highlight of the trip! While the waterfall is amazing, what lies behind it is the best part. To the right of the falls is a giant staircase. Climb to the top for another glorious view and THEN continue to hike back for miles so you can see unending waterfalls. Every few hundred feet is another giant waterfall. The pictures don't do it justice. We only hike about 2 miles out, but it went on much longer.

Parking was free and there were restrooms and a small cafe on site.

After a day of exploring, we headed toward our hotel in downtown Reykjavik. I don't have pictures, but for dinner, we found an amazing food hall called Hlemmur Mathöll. It had about pizza, burgers, salads, Thai, Icelandic, Meixcan ice cream, drinks and more.

From there, we took a short walk to Brewhouse, a Scottish brewery Tom and I really like (it's in several UK cities). We also walked along the water for some midnight sun pictures.

The Blue Lagoon is definitely the most touristy thing to do in Iceland but we LOVED it. You need to go when it opens to avoid the crowds. It opens at 8 a.m., but we entered at 9 and felt it was very open and enjoyable. It's only 20 minutes from the airport, so if you arrive in the morning, I recommended heading straight to the lagoon.

You will be given a wristband that opens and locks your locker, but it is also used for one free drink (wine, beer, or green juice) and one free mud mask. If you want more drinks or mud, you can scan your wrist band and they'll charge you afterward (think stadium beer prices). Prior to getting in the water, you're required to bathe and cover your hair in their conditioner. It's recommended that you don't get your hair wet. Listen to them. I dunked my hair and it felt like straw for about three weeks. They have amazing shampoo and conditioner to use afterward, so use their stuff! They also have towels, so all you need is a suit and flip flops.

TIP: Book far in advance. It sells out quickly and the price goes up the closer you get to your reservation date. We paid $85 each and booked about three weeks in advance and only had a couple of days to choose from. Prices start at $60 if you book early enough.

The drive to Gullfoss is gorgeous. This was the largest waterfall and it felt as if we were in a movie. There were many tourists, but it was still beautiful and worth it. There was a restaurant and bathrooms on site, too.

We wore rain gear because we wanted to get our money's worth, but it wasn't necessary :)

From the waterfall we drove to the Geysir. It goes off about every 15 minutes. We didnt' have time, but there was a hike that you could take to the top of a hill that overlooked the entire area.

Parking for each was free.

Downtown is very similar to Anchorage, AK if you've ever been there. People don't come out until around 10-11 p.m. because the sun doesn't set. We found that the best restaurants and bars were near Rainbow Street.

I DID try the famous hotdog stand, but honestly, I didn't like it.

I can't remember, the name, but we found a "Library" Bar that had live music and books everywhere. That was our favorite.

We then made friends at another local bar and found that the people were incredibly nice and most people wanted to talk and get to know the tourists.
