Observe the Northern Lights in Iceland

Add magic and adventure to your Valentine's weekend by heading for spectacular Iceland on a Northern Lights tour. Explore's Icelandic Escapades holiday offers four days of touring the country, with the chance to witness the incredible Aurora Borealis and explore the rugged volcanic landscapes and erupting geysers, as well as experience the thermal waters of the Blue Lagoon. There is the chance to spend time in the country's capital, Reykjavik, renowned for its friendly culture and fantastic nightlife. Tours cost from £729 per person and include return flights, three nights' hotel accommodation, transport and the services of an Explore representative.

Snuggle up in Sweden's floating hotel

Couples after a quirky escape will love West Sweden's floating hotel and restaurant Salt & Sill. Set on a peaceful island in the Skagerrak strait, the hotel invites you to feel inner calm (and very smug) as you chill out with your loved one in an outdoor hot tub overlooking the ocean before dining at the restaurant. Arriving Saturday 14 February, the Valentine's package costs from £135 per person and includes one night's B&B, a three-course dinner, a glass of sparkling wine and a box of chocolate truffles in your room.

Hole up in a treehouse in Tuscany

Treehouses are the epitome of romance and provide the perfect setting to escape for a romantic weekend away. While you might find a few around the UK, Tuscany is an unexpected destination for a treehouse escape and this romantic room offers an excellent alternative to the many romantic hotels in Florence. Immersed in the rolling countryside and surrounded by olive trees, casaBARTHEL offers a queen sized bed and exceptional views to make you feel like you are floating above the famous countryside. The romantic room, just 20 minutes from Florence's Duomo, has a fire place and a black board for you to write love notes for each other.

Explore authentic Asia

For a far-flung escape with added culture and history, visit Asia on an authentic holiday where you can travel by local transport taking in vibrant Bangkok, visit the ancient temples of Angkor and cruise between the floating fishing villages on Lake Tonle Sap. Explore's 10-day Indochina Encounter uncovers the sights of Vietnam, Cambodia and Thailand. The tour takes in many of South East Asia's incredible sights including the Cu Chi tunnels from the Vietnam War and the colonial buildings of Battambong. For the perfect romantic rendezvous, you can discover the inspiring temple complex of Angkor in Siem Reap at sunrise. Tours cost from £1,359 per person, including flights, hotel accommodation, five meals, transport and the services of a driver and tour leader.
