Taking a 7 day trip to Iceland and need some assistance.
Here are my tentative plans, but I need some help as I plan to tour DIY style once I get to Iceland. (vs taking a group tour)
ARRIVE: April 1st at 4AM (early I know) and planned to stay at a hostel and catch up on my sleep for a few hours. Then I would spend the rest of that day exploring Reykjavik. I also plan to rent a car (4WD) from the airport. I'm trying to decide between the Kex Hostel and the Loft Hostel if anyone has a preference. I know there is a lot to see and do in Reykjavik, but my real goal for this trip is to explore the beautiful landscape.
DAY 2 (April 2nd)—DAY 6 (April 6th) Driving wherever I want. Most of what I would like to do is on the west side of the country. Would it make sense to do a half circle vs circling the entire country? I don't want to be rushed. I'm having difficulty figuring out where I would need to stop and stay the night along my journey. A few things I would like to do are visit the Blue Lagoon, Horseback Riding, Viking Boat Tour, visit the beaches at Vik, Snaefellsness peninsula,Skogafoss waterfall, and seeing a few puffins wouldn't hurt either:) I need help determining what route would make the most sense.
DAY 7: Depart Reykjavik at 3:30 PM. I figure I would spend the morning in Reykjavik enjoying the last bit of my trip there.
I'm sure some of you may need more details, but this is my first time planning a trip. If it weren't for needing a place to sleep outside of Reykjavik I would just wing it. But I don't know if that's the best plan.
