During my first trip to Iceland, I visited the Blue Lagoon, one of the country's most famous tourist attractions. With its milky-blue waters set in a black lava field, it's easy to see why it draws so many visitors — the landscape truly feels otherworldly.

Plus, it's close to Iceland's international airport, making it a convenient stop for travelers who need to kill time after landing or before departure.

The cost of admission varies depending on the time of day and package booked, but it starts at about $124. My ticket came with a silica mud mask that I wore in the water.

I was also interested in enhancing my experience by visiting the on-site spa, which includes a multistep wellness ritual. But full-day admission starts at more than $1,300 per couple, which was too pricey for my budget.

Though the lagoon is undeniably pretty, it's big and often crowded. In fact, I was left with the impression that the Blue Lagoon may be a victim of its own success.

I still had a nice experience and can see why it's so popular. But after going to other lagoons and hot springs in Iceland, it isn't my first choice for a return visit.

The Sky Lagoon is only a 15-minute drive from downtown Reykjavík, so it was more convenient to access during my trip.

Unlike at the Blue Lagoon, I immediately felt a sense of calm when I walked in. It has a serene atmosphere that I thought felt closer to a traditional spa, incorporating elements of Iceland's unique natural environment throughout.

Basalt lava rocks and moss-covered hills surround the warm waters, and even the swim-up bar is camouflaged by natural elements.

This spot has the feel of an infinity pool with stunning views of the Atlantic Ocean, and the beautiful, wild Icelandic landscape I flew across an ocean to experience.

I would've been happy just sitting back, enjoying the view, and soaking up the peaceful atmosphere at the Sky Lagoon.

But admission (which starts at about $133) also comes with access to the Skjól ritual, which is a seven-step process that draws on Iceland's history of wellness practices. It includes a series of alternating hot and cold circuits, including a cool-mist rain shower and a sauna with stunning views.

I don't usually enjoy saunas because the heat makes me feel lightheaded, but I pushed my limits and stayed to enjoy the view. I also really enjoyed the salt scrub.

For me, the one downside to visiting the Sky Lagoon is that children under 12 aren't allowed in. That means I couldn't go when I visited Iceland with my children.

But the nearly adult-only atmosphere is a definite plus for many people and adds to the upscale environment that helps the Sky Lagoon stand out.

I hope to one day visit some of Iceland's other lagoons, but for now, the Sky Lagoon is my top pick.
