Dates are flexible. This day-by-day plan is provisional until you choose exact travel dates.
Take a pre-booked Flybus or similar airport coach from Keflavík Airport toward Reykjavík. Allow about 45–60 minutes on the coach, plus time for waiting, luggage and—if your ticket includes it—the smaller onward shuttle to your hotel. This is an airport transfer, not Reykjavík’s local bus; Iceland has no passenger rail service. Check the coach’s current schedule and drop-off arrangements against your flight, and keep your first evening flexible in case of delays.
Once you’ve checked in, head to Harpa Concert Hall on the waterfront. Its striking glass façade is worth seeing from outside, and the public foyer is a good warm, sheltered stop; access to performance spaces depends on events, so don’t count on a concert without a ticket. Allow around 45 minutes, then walk east along the seafront to Sun Voyager (Sólfar), a quick, scenic photo stop. In late October, daylight is limited and wind can make this stretch feel colder than expected, so go only if conditions are comfortable and bring a hat and gloves.
Walk back toward downtown for Bæjarins Beztu Pylsur, the well-known hot-dog stand near the harbour. It’s a casual, no-reservations option; budget roughly ISK 1,000–2,500 per person depending on what you order. Opening hours can vary, so check on the day. From the waterfront, the central streets are walkable, but Reykjavík’s weather changes quickly—take a taxi if you’re tired or the wind and rain make the stroll unpleasant.
Start at Hallgrímskirkja on Skólavörðuholt; allow 1–1½ hours to look around and, if the tower is open, take the lift up for a superb view over the rooftops. The church is generally free to enter, with a separate charge for the tower; check current opening times and service schedules before you go, as access can change. From there, stroll downhill toward Laugavegur—it’s an easy walk, though the hill and late-October weather can make grippy shoes and a waterproof layer welcome.
Give Laugavegur about an hour to browse, dipping into the side streets for Icelandic design shops and small boutiques. Then stop at Sandholt on Laugavegur for a pastry, coffee or light lunch; budget roughly ISK 1,500–3,500 per person. Continue downhill to The Settlement Exhibition on Aðalstræti, around a 10–15-minute walk away. Its Viking-era archaeological remains are presented in a compact, atmospheric museum; allow 1–1½ hours and check the current hours and admission price before setting out.
Walk about 10 minutes toward the harbour to finish at Reykjavík Art Museum, Hafnarhús, allowing 1–1½ hours for contemporary Icelandic art. Museum hours and exhibitions vary, so check the schedule before you visit; if you’re watching costs, look into current combination-ticket options for the city’s museums. The centre is very walkable, but local buses are handy if the weather turns—check the Strætó app for routes and fares.
Book a full-day Golden Circle coach tour in advance; without a car, this is the practical way to reach Þingvellir National Park, Geysir Geothermal Area and Gullfoss in one day. Allow roughly 8–10 hours door to door, including pickup and stops, and confirm all three are on your chosen tour’s itinerary—routes and stop lengths vary. Bring a packed snack or buy something before boarding, since lunch arrangements differ by operator. A full-day tour commonly costs around ISK 10,000–20,000, but check the current price and pickup point when booking.
At Þingvellir National Park, walk the paths through the rift landscape and allow time for the viewpoints; your stop may be brief, so follow the guide’s return-time instructions. Next, expect around 45–60 minutes at Geysir Geothermal Area in Haukadalur: Strokkur erupts frequently, but give it a little time and space, and stick to marked paths around the hot ground. Continue to Gullfoss, where the river plunges into a canyon; plan on another 45–60 minutes for the viewpoints. October can bring wind, rain, icy patches or tour changes, so wear warm layers and grippy footwear, and check the operator’s updates before setting out.
After the coach drops you back in Reykjavík, head to Messinn downtown for seafood—allow about ISK 4,000–7,000 per person before drinks. It’s a satisfying end to a long day, but check that the kitchen is still serving when your tour is due back and reserve if possible; if you’re running late, call rather than assuming you can be seated.
Late October brings short daylight hours and changeable weather; check tour, museum, and transit schedules close to travel, and keep outdoor walks flexible.
Head to Árbær Open Air Museum first; allow 1½–2 hours to wander among the historic buildings and get a feel for everyday life in Iceland before Reykjavík grew into a capital. It’s outside the centre, so use the Strætó app to check the current bus route and journey time from your accommodation, or take a taxi if you want to save time. Late-October opening days and hours can be limited, so confirm the museum is open before setting out; dress warmly, as much of the visit is outdoors.
From Árbær, continue to Perlan in the Öskjuhlíð area. Allow roughly 30–45 minutes by bus, depending on connections, or take a taxi for the more direct trip. The indoor nature exhibits make this a good weather-proof stop, and the observation deck is worth visiting if the sky is clear; budget 2–3 hours. Admission is typically several thousand ISK, with the exact price depending on ticket type, so check and book ahead if needed. Afterward, travel to Sky Lagoon in Kópavogur. Book your entry in advance and check the lagoon’s current shuttle or bus arrangements and return times before you go; allow 2–3 hours there, plus transit, and expect admission to cost roughly ISK 8,000–15,000 depending on the package.
Finish with dinner at Café Loki, near Hallgrímskirkja. It’s a handy place to sample Icelandic dishes such as lamb soup, rye bread or skyr; plan on about ISK 3,000–6,000 per person. Check the kitchen’s closing time, particularly in late October, and leave enough time to get back from Sky Lagoon—evening bus services can be less frequent than daytime ones.### Morning
