7 Day itinerary -- are 3 long tour days too much?

Can you swap day 2 and 3 so you don’t have the bus/car tours 2 days in a row. Also, I would not want a late night jeep tour and then have to get up early the next morning for a tour.

I was just in Reykjavik for 5 days and only did 1 group tour and wish I had more. So, I would prioritize the 3 bus/car tours. Just spread them out better if you can.

Have you considered a multi day tour? That would eliminate the backtracking even with the tours, and would allow you to have moire time actually visiting the places.

If you don't want to do that, then I agree, try to mix it up a bit and do the tours every other day.

I would not do a northern lights tour and then a tour in the morning. You won't get back until around 1, even 2am.

I think you mean the Golden Circle, and that is a really easy tour day, but like I said I would not do a tour the morning after a NL tour. Pickups for the tours are around 8am, so that would be a rough day.

Instead of a NL tour via boat, I would stick to a land based one. October weather can be anything and do you really want to be out on a boat in the cold, rain, and extreme wind? Land based have chairs for you, winter jumpsuits to keep you warm hot cocoa and a bus to go sit in if you are really cold. If you need a recommendation I really like Aurora Experts. We have used him a few times and he is excellent!
