Llys-y-Frân reservoir, Pembrokeshire

Llys-y-Frân Lake in Pembrokeshire is being redeveloped into an activity centre. There will be about nine miles of cycle trails around the reservoir, a pump track to practise BMX and mountain-biking skills, and new watersports such as paddleboarding and pedalboarding (ie, a pedal-powered paddleboard with a handrail). Other activities include walking, fishing, archery and axe-throwing. Visitors can stay on the new 50-pitch campsite and eat at the refurbished cafe. The 142-hectare (350-acre) site is near the foot of the Preseli Hills, about 11 miles from Haverfordwest.

Nottingham Castle

The long-awaited reopening of Nottingham Castle is expected this spring – work began in 2017 and the castle has been closed to visitors since July 2018. During the £24m project, the grounds have been remodelled to reveal more of the medieval site and improve views across the city, and a new visitor centre has been built. The Ducal Palace has been returned to its 19th-century layout and a gallery devoted to Nottingham’s most famous son, Robin Hood, has been added. More of the castle’s caves have been opened up – the city is built on more than 500 caves – and the displays in the 17th-century Brewhouse Yard cottages have been improved. There will be a year-round programme of outdoor events in the castle grounds. Heritage buffs can sign up to the mailing list to be the first to know when tickets go on sale.

Mary Shelley’s House of Frankenstein, Bath

Don’t expect a sedate literary museum devoted to the life and times of Mary Shelley. The new House of Frankenstein is an immersive, multi-sensory attraction focused on her infamous creation: the monster. It is set in a four-storey townhouse in Bath, with a dark, dank basement, ominous audio and visual effects, assorted body parts and “some scenes of a disturbing nature”. There is also an escape room, set in Victor Frankenstein’s attic. Children must be accompanied by an adult, and it may not be suitable for under-12s.
• Opens in June; from £11.25, tickets on sale now in the form of a voucher code, houseoffrankenstein.com

Wave Garden Spa, Snowdonia

The park already has a surf lagoon, indoor adventure courses and outdoor ziplines, plus glamping pods to stay in, and a new hotel and restaurant will open on the same day as the spa. “Thrill and chill” packages will be available for guests who want to combine surfing with a spot of pampering.

Northern Roots, Oldham

A 65-hectare green space in Oldham is being turned into the UK’s biggest urban farm and eco-park. The site is five minutes from the town centre and stretches from Alexandra Park in the north to Bankfield Clough in the south, with woodland, moorland and wetlands. It is already a place for walking, running, mountain biking, horse-riding and birdwatching, and there are plans for more activities, such as a high-wire course, as well as community projects including beekeeping, animal husbandry and forestry. Green ambitions include generating renewable energy, becoming a “carbon farm” (sequestering atmospheric carbon into the trees) and increasing wildlife by 25%.

Rye Harbour Discovery Centre, East Sussex

The Rye Harbour nature reserve has a new discovery centre, with information about the reserve and its wildlife, exhibitions, events, a cafe and a shop. The building was designed by the architects behind the award-winning Scottish Seabird Centre in North Berwick, and is as sustainable as possible: it has locally sourced sweet chestnut cladding, natural light and ventilation, photovoltaic panels on the roof and air-sourced heat pumps. There is a community wildlife garden outside. The centre has great views over the reserve and is close to three different habitats – grassland, saltmarsh and shoreline – and a birdwatching hide. The 465-hectare reserve, which is on the coastal boundary of East Sussex and Kent, is home to 4,275 species of plants and animals, including more than 200 rare or endangered birds and mammals.
