Durdle Door costs nothing to see and £15 to park at. Checked 2026 prices for the Tank Museum, Monkey World, Corfe Castle, the swannery and Swanage Railway.

Dorset’s best-known attractions are free and its cheapest-sounding ones are not. You can stand under Durdle Door without paying a penny, but you cannot park within reasonable walking distance for less than £15. A day at the Tank Museum costs a family of four £48.80 and includes a free annual pass, which makes it one of the better-value tickets in the county if you go twice.

Every price and opening time below was checked against the venue’s own website on 9 August 2026. Where a place has separate peak and off-peak pricing, or a cheaper online rate, both are given.

One thing that applies everywhere this summer. Under the government’s Great British Summer Savings scheme, VAT on admission to eligible attractions is cut from 20% to 5% for visits dated 25 June to 1 September 2026. Several Dorset venues have not repriced their websites, so the amount you pay at the till may be less than the figure advertised. It ends on 1 September.

Free, or as good as

Maiden Castle, Dorchester. The largest Iron Age hillfort in Britain, a mile south west of the county town, with ramparts you can walk the whole way round. English Heritage runs it, entry is free and it is open “any reasonable time during daylight hours”. There is no ticket office, no café and no fuss. On a clear day it is the best view in central Dorset and it costs nothing.

Durdle Door and Lulworth Cove. The arch and the cove are free to visit and always have been. The cost is the car park, which the Lulworth Estate runs and charges for every day of the year including bank holidays. Durdle Door is £15 for up to six hours, £25 for up to nine and £35 beyond that, with motorbikes at £7, £12 and £15. Lulworth Cove is £9 for up to three hours, £17 for six, £25 for nine and £32 beyond, and it takes coaches at £30 to £65. Lulworth Castle’s own car park is £4 all day, which is the cheapest way onto the estate if you are prepared to walk. The estate says parking income funds the footpaths, steps and beach access, which given the state of the coast path is not an unreasonable claim.

Durlston Country Park, Swanage. A clifftop country park run by Dorset Council with a free visitor centre inside the Victorian Durlston Castle, a café, a gallery and rooftop views over the Channel. Entry is free and parking is the only charge: £2.50 for one hour, £4 for two, £5.30 for three, £6.60 for four and £7.90 for five hours or more. It works on number plate recognition and you pay when you leave, and the machines take cash or contactless because the phone signal there is poor. The park and car parks are open sunrise to sunset all year; the visitor centre is 10am to 5pm from 1 April to 31 October and 10am to 4pm the rest of the year.

Worth paying for

The Tank Museum, Bovington. The biggest single draw in east Dorset and, on price, the shrewdest ticket in the county: every admission includes a free annual pass, so a second visit within the year costs nothing. Adult admission is £19.60 booked online against £24.50 on the door, children are £4.80 online against £6, concessions £12.25, and a family of two adults and two children is £48.80 online against £61 at the gate. Parking is free. Serving armed forces personnel with a valid MOD90 go free.

Monkey World, Wool. The primate rescue centre near Wareham, open every day from 10am to 5pm and closed only on Christmas Day. Adults £18 online or £19 at the gate, children aged 3 to 15 £12 online or £12.75, under-3s free, seniors £12, and a family of two adults and two children £50.75 online or £53.50 at the gate. Adopting a primate gets you unlimited entry for a year, which is worth doing the sum on if you live locally.

Corfe Castle. The ruined castle above the Purbeck village, run by the National Trust. 25 July to 31 August is peak season, when an adult is £17.60 with Gift Aid or £16 without, a child aged 5 to 17 is £8.80 or £8, and a family of two adults and up to three children is £44 or £40. Off peak it drops to £16.50 and £15 for an adult. National Trust members and under-5s go free. Worth knowing this month: there is a 20% discount on entry after 2.30pm from 25 July to 31 August, and open-air theatre and cinema evenings run through August. The Purbeck Breezer no. 40 from Poole to Swanage and no. 30 from Swanage to Weymouth both stop at the castle, at £3 per person until the end of December.

Swanage Railway. Six miles of preserved steam and diesel railway between Swanage, Corfe Castle and Norden. A day ticket is £27.50 for an adult and £14 for a child aged 5 to 15, with under-5s, dogs and bicycles free, and a family ticket at £77.50 covering two adults and three children or one adult and four. A full-line single is £14, and a short hop from Harmans Cross is £7. Fares have been at this level since 1 February 2026. It is the most expensive day out on our list and also the only one where the travelling is the point: park at Norden, take the train in, and you avoid Corfe village and Swanage seafront parking altogether.

Abbotsbury Swannery. The only managed colony of nesting mute swans in the world, on the Fleet lagoon behind Chesil Beach. Adults £15, children aged 5 to 15 £7.50, open every day from 10am to 5pm with last entry at 4pm. It is seasonal: open from mid-March to the end of October and shut from November until mid-March, so it is not a winter option. A £20 adult passport covers the swannery and the estate’s other attractions.

Sherborne Castle and Gardens. Sir Walter Raleigh’s house and its Capability Brown landscape, on the edge of Sherborne. Gardens only are £13 for an adult and £4 for a child aged 3 to 15; castle and gardens are £17.50 and £4, with under-3s free. It is closed on Mondays except bank holidays. The gardens open at 10.30am from April to September with last admission at 4pm; the castle itself opens at noon from May to September with last admission at 3pm, and tours run for about an hour. RHS members get free entry to the gardens every Wednesday from 1 April to 30 September 2026. The ruined Sherborne Old Castle across the lake is a separate English Heritage site.

Nothe Fort, Weymouth. The Victorian fort on the headland above Weymouth harbour, with tunnels, ramparts and Jurassic Coast views. Adults £11, children aged 5 to 16 £4.50, under-5s free, a family of two adults and two children £26.50 and a single adult with two children £15.50. Like the Tank Museum, admission includes a free annual pass. Open daily 10am to 4pm.

Picking a day out by where you are

  • Around Dorchester: Maiden Castle for free, the Tank Museum and Monkey World half an hour east, Abbotsbury Swannery half an hour south west.
  • Around Weymouth and Portland: Nothe Fort in the town, Abbotsbury along the coast, Durdle Door and Lulworth Cove twenty miles east. Use the Mount Pleasant park and ride in summer rather than the seafront.
  • Around Purbeck and Swanage: Corfe Castle, Durlston Country Park and the Swanage Railway are all within a few miles of each other, and the railway links two of them.
  • Around Sherborne and the Blackmore Vale: Sherborne Castle and the Old Castle, then the Heart of Wessex railway line for a cheap afternoon out to Yeovil or Castle Cary.
  • Around Bridport and the west: the Jurassic Coast itself, from West Bay to Charmouth and Lyme Regis, which costs nothing but the parking.
