Great outdoor activities for all agesAt HYMB we understand that people have been unable to meet up with family and friends. There have been limited circumstances to get out and experience the fresh air with minimal opportunities to interact outside of the home environment which has proven to be detrimental for both mental and physical well-being. Until the pandemic no-one questioned the freedom to experience outdoor activities in Hertfordshire and have fun. At HYMB, we have a wide range of outdoor activities to suit all ages, abilities and interests. Have a look at our website and we are sure you will find some outdoor activities to get you active and outside.

Brilliant place for open water swimming. Well managed and friendly atmosphere for any ability. Woke me up better than any coffee or yoga session this morning.

A great place. For large and small groups. I've taken my 9, 10 & 11 year old with friends over school holidays and a whole class of 30 for their leaving celebration. They've done paddle boarding, rafting, kayaking and more. The price is great for all day and I have no worries leaving them, the staff are friendly and knowledgeable. There are wet suits and changing facilities. A basic shower. There is also a cheap tuck shop which the kids love too. Highly recommended.
