Copenhagen's Rosenborg Castle by bike in October

What you see inside Rosenborg

Rosenborg Castle (Rosenborg Slot) stands behind a moat and clipped hedges in the King's Garden, Dutch Renaissance red brick with pale sandstone dressings and three copper spires. Upstairs, the Long Hall holds the coronation thrones with silver lions flanking them. The Treasury is in the vaulted basement, and the regalia are the reason the queue exists.

The Royal Danish Collection runs the castle. Its website moved from kongernessamling.dk to denkongeligesamling.dk. An old bookmark sends you to the wrong address.

Tickets and the door queue

Buy online. A ticket is 140 kr online and 150 kr at the door, and under 18s enter free. Entry is released in slots of 10 minutes, so a group books one slot together and arrives as one. English guided tours, and school or organised groups, are arranged in advance through The Royal Danish Collection.

The Royal Palace Pass is 245 kr online and covers Rosenborg, Amalienborg and Christiansborg for 72 hours. Take it if two of the three are already in your plan.

Bags, prams and stairs

Backpacks are banned. Handbags are capped at 15 × 23 × 15 cm, so carry the small bag that day and leave the rucksack at your hotel. Prams stay at the door.

There is no lift. The Treasury stairs rule out wheelchairs beyond the ground floor, and that is the floor the regalia are not on.

Hiring a bike at the castle gate

Rosenborg Cykler (Rosenborggade 3K) is the closest rental to the gate, a block from Nørreport. Rows of black city bikes and small three-gear Bornholm bikes stand out on the pavement, helmets on hooks, repair stands and wheels inside.

A standard bike is 150 kr for six hours or 200 kr for 24. A week is 700 kr. An e-bike is 279 kr for six hours or 349 kr for 24, and a cargo bike is 450 kr for six hours. Helmets run 35 kr to 150 kr. Every hire comes with a safety briefing, and they will take a walk-in for several bikes at once. Hours are 08:30 to 18:00 Monday to Friday, and 10:00 to 15:00 on Saturday.

KGS Have Cykler (Sølvgade 26) is the corner shop directly across from the King's Garden wall, three-wheel Christiania cargo bikes with wooden boxes lined up on the kerb. A city bike is 200 kr a day or 550 kr a week. The Christiania cargo bike is 500 kr a day and the electric version 750 kr. Family and multi-bike packages are discounted, and they will deliver within 5 km for 250 kr, which is the move if you are not all collecting at the same hour. Hours are 10:00 to 18:00 Monday to Friday, and 10:00 to 15:00 on Saturday.

Both shops are shut on Sunday. For a Sunday ride, collect on Saturday and keep the bikes overnight.

Bike Copenhagen with Mike (Sankt Peders Stræde) is in his 20th season in 2026, riders gathering on the cobbles outside a narrow shopfront hung with his own fleet of upright bikes. He runs small scheduled groups and bookable private tours, price band kr kr, quoted on his own booking calendar rather than a fixed list. He is a one-man operation, so a large party needs to arrange a private date with him directly by phone or email. The core Hello Copenhagen ride and the private tours are listed as year-round, and the weather-dependent seasonal rides stop in October.

Kongens Have

Kongens Have (King's Garden) is free and unticketed, gates open 07:00 to dusk in October. Dead-straight gravel allées run under clipped limes. The domed Hercules Pavilion sits off one of them, the seated Hans Christian Andersen statue off another, and a walled rose parterre keeps to itself with the castle's copper spires over the hedge line.

Cycling is not allowed on the inner paths. Wheel the bikes through at walking pace, or leave them at the racks on Øster Voldgade and collect them on the way out. This is where a riding party regroups without anyone paying for anything.

Restaurant Orangeriet is the one restaurant inside the garden, a 200-year-old white orangery pavilion with tall arched glass doors and a broad terrace of tables under the trees. Lunch runs 11:30 to 15:00 and dinner from 18:00. Sunday service is not guaranteed, so confirm the day when you book. Lunch is smørrebrød and the evening à la carte is pricier, kr kr kr, and they take group bookings and private functions. Diners in 2026 rate the setting above the portions for the money, so come for the pavilion and order lunch.

Museums beside the garden

The David Collection (Davids Samling) (Kronprinsessegade) faces the garden railings from a neoclassical apartment house. Entry is free, with no booking and no ticket. Dark-walled cabinets hold Islamic art: illuminated manuscripts, lustreware bowls and inlaid woodwork. A hushed Danish Golden Age floor sits above. It opens Tuesday to Sunday 10:00 to 17:00, Wednesday to 21:00, and closes Monday. The converted townhouse has narrow rooms, so split a large party and go in waves.

SMK, the National Gallery of Denmark (Statens Museum for Kunst) (Sølvgade) is five minutes along the garden's north side, an 1896 Italianate brick palace joined to a modern wing by the glass-roofed Sculpture Street, the Østre Anlæg lake and its willows behind. Entry is 140 kr, 95 kr under 27, free under 18. It opens Tuesday to Sunday 10:00 to 18:00, Wednesday to 20:00, and closes Monday apart from announced autumn-holiday Mondays. It has a cloakroom, a lift, a café and booked guided tours. The Parkmuseerne ticket is 345 kr for six museums and stays valid a year.

Den Hirschsprungske Samling (The Hirschsprung Collection) (Østre Anlæg) is a small marble-fronted pavilion standing alone among the trees, Skagen-painter canvases hung on deep coloured walls in intimate top-lit rooms. Entry is 110 kr, or 75 kr under 29 with one friend under 29, free under 18. It opens Tuesday to Sunday 10:00 to 17:00, closes Monday, and stays open to 20:00 on the last Thursday of the month. An hour covers it, so it fits between the castle and the ride.

Arbejdermuseet (The Workers Museum) (Rømersgade) is the preserved 1879 Workers' Assembly Hall. The festival hall is gas-lit, a 1950s Copenhagen flat has been rebuilt with its floral wallpaper, and the old beer hall downstairs still has its long wooden tables. Entry is 135 kr, 110 kr for students and 18 to 25, free under 18, with 10% off online. It opens daily 10:00 to 17:00, Thursday to 20:00, and takes booked group tours. It is the sixth Parkmuseerne museum and the counterweight to the gold: this is how the rest of Christian IV's city lived.

Botanisk Have & Palmehuset (Botanical Garden and Palm House) (Øster Voldgade) is straight across the road from the castle. The 1874 palm house is cast iron and curved glass under a dome, with a spiral iron staircase climbing into the canopy, and the rock garden is terraced above a lily-covered lake. The garden is free. Palm House tickets, including the Butterfly House, start at 40 kr.

Parts of the glasshouse are shut in stages for restoration into 2027, and there is scaffolding over the section being worked on. The new Natural History Museum under construction here does not open until 6 March 2027. Walkways inside are narrow. Book the glasshouse ahead.

Breakfast and lunch at Torvehallerne

Torvehallerne (Israels Plads) is two glass-and-steel pavilions three minutes from Nørreport, more than 100 stalls under the roofs, oyster ice and smørrebrød counters and open coffee bars, flower buckets and bike racks spilling onto the square between them. Coffee and bakery stalls open at 07:00. The market runs 10:00 to 19:00 Monday to Friday and 10:00 to 18:00 at weekends. Entry is free and a plate, or a coffee and pastry, is kr kr.

Nothing is booked and there is no door policy. Standing counters fill between 12:00 and 14:00 and it is a crush.

Riding on from the castle

Nyboder is where Christian IV housed his navy while he was building Rosenborg: long unbroken terraces of ochre Nyboder yellow single-storey row houses, red pantile roofs, black-painted doors, arrow-straight cobbled lanes. These are lived-in private homes. Ride slowly, keep the noise down and do not photograph into windows. The Royal Life Guards march daily to the palace from the barracks on the garden's edge.

Dronning Louises Bro (Queen Louise's Bridge) is 10 minutes' ride from the castle, granite balustrades over the city lakes and broad red asphalt tracks carrying a solid stream of commuters, with people perched on the parapet benches looking down the water. It is the busiest cycling stretch in Denmark at 40,000 riders a day. Ride single file and keep right. Never stop in the track.

Kastellet is a star-shaped earthwork fort, grass ramparts above a water-filled moat, rows of deep-yellow barracks with red roofs, and a red-painted Dutch windmill on the northern bastion. Gates open 06:00 to 22:00 daily and entry is free. It is still a working military site, and cycling is not permitted on the ramparts. Walk the bikes and take the rampart circuit on foot.

Rundetaarn, up a ramp instead of stairs

Rundetaarn (The Round Tower) is under a kilometre from the castle, a 1642 cylindrical brick observatory with a gilded rebus inscription on its face. A 209-metre cobbled spiral equestrian ramp winds up to an open platform above red-tiled roofs and green copper spires, and there are no stairs until the very top. Entry is 60 kr, 40 kr for students with ID, free under 18. It opens 10:00 to 21:00 Monday and Tuesday, and 10:00 to 18:00 Wednesday to Sunday.

Tickets are sold only at the door on arrival and staff enforce a hard capacity cap, so peak waits run up to 20 minutes. Booked group guided tours are the exception to the door-only rule. The listed building has no lift and suits neither wheelchairs nor pushchairs.

Best time to go in October

The lime avenues in the garden turn this month. It is the one week-by-week change worth timing. Guided rides from this quarter run seven days a week, season 11 October 2026 to 7 November 2027, and a private date with a one-man operator needs more notice than a scheduled one.

Go to the Botanical Garden before 24 October if you want the longer afternoon; the summer opening of 10:00 to 17:00, Tuesday to Sunday, runs to that date. Rundetaarn's observatory slot on Monday and Tuesday between 18:00 and 21:00 is the one evening thing in walking distance of the castle. At Torvehallerne, 10:00 to 11:30 on a weekday is the calm window, so make it the pre-ride breakfast rather than the post-castle lunch.

Is it worth it

It suits a visitor who wants the regalia under glass and then a flat ride out through the naval terraces to the fort. It asks for a booked slot, a bag no bigger than 15 × 23 × 15 cm, and legs for the Treasury stairs.

Practical notes

Both bike shops close on Sunday, the David Collection and the Hirschsprung close on Monday, and SMK closes Monday except on announced autumn-holiday Mondays. Book Rosenborg's slot and any English guided tour in advance through The Royal Danish Collection, and expect to buy Rundetaarn's ticket at the door.
