Eleven hours, both things
These are the two things almost everybody flies to Iceland for, and they are in opposite directions from Reykjavík. The Golden Circle runs east; the Blue Lagoon is south-west, on the way to the airport. Doing both in a day means eleven hours and about two hundred and eighty kilometres — and for a lot of people with three days in Iceland, that is exactly the right trade.
Quick answer
The short answer. $245 for the eleven-hour version with Kerið crater on the way round, rated 4.9 across 6,006 reviews. Check whether lagoon entry is included — on some listings it is not. If you have four days or more, split them: the loop on one day, the lagoon on the way to the airport on the last.
Why it works better as a tour
You are not paying for a bus. You are paying for somebody else to own the timing risk.
The Blue Lagoon runs on timed entry slots and it sells them out. That single fact is why combining it with the Golden Circle is genuinely hard to do yourself and easy to buy.
Self-driving, you have to guess when you will finish at Gullfoss, add an hour and a half of driving across the whole of the capital region, and then hit a slot you booked weeks ago. Gullfoss in good weather is somewhere people lose forty minutes without noticing. Miss the slot and you have paid for a lagoon you did not get into.
On a tour, the operator holds the slot and the coach arrives when it arrives. That is what the price difference actually buys — not the transport, the certainty.
The other reason is the drive itself. After eight hours of sightseeing, the run from the Golden Circle across to Grindavík is the least appealing hour of driving in the country, and it is the one you would be doing tired.
Before you book
The listings on this route vary more than they look.
On some Golden Circle and Blue Lagoon tours the price covers transport and you buy entry separately. That is a large difference — entry is one of the more expensive tickets in Iceland. Read the inclusions before comparing two tours on price.
The Blue Lagoon sells several packages. The basic one includes a silica mud mask and a drink; the higher ones add a towel, a robe and slippers. Tours generally book the basic tier, so bring your own towel unless it says otherwise.
Pickup around eight, back around seven. Almost all of the sitting-down is in the vehicle. If you have arrived that morning on a red-eye, this is not the day for it.
Fully, without a swimsuit, in a communal changing area. This is standard everywhere in Iceland and it is enforced. Nobody warns visitors and it surprises them every time.
At $126 the Secret Lagoon version is a hundred and twenty dollars cheaper, sits on the loop itself so there is no cross-country drive, and the pool has been open since 1891. It is smaller, plainer and, for a lot of people, better.
If you have four days, split them instead. Here is the one-day loop on its own.

Common questions
Yes. The combined tour runs about eleven hours and covers roughly 280 kilometres, with Kerið crater on the way round. It costs $245 and carries 6,006 reviews at 4.9.
Not always. Some listings cover transport only and leave the entry ticket to you, which is a significant difference. Check the inclusions before comparing two tours on price.
If you have four days or more, yes — do the loop on one day and the lagoon on the way to the airport on your last. With only two or three days, the combined tour is the better use of the time.
They are in opposite directions from Reykjavík. The lagoon is south-west on the Reykjanes peninsula near Grindavík, about an hour and a half from the end of the Golden Circle loop.
For many people, yes. It is on the Golden Circle route itself so there is no cross-country drive, the tour is $126 rather than $245, and the pool has been open since 1891. It is smaller and plainer, which is either the point or the problem depending on you.
Yes, fully and without a swimsuit, in a communal changing area. It is standard practice in every Icelandic pool and it is enforced by attendants. Worth knowing before you arrive.
