HYMB – Herts Young Mariners Base

What will students see and do?

Located in the serene River Lee Country Park in Lee Valley (also known as Lea Valley), Herts Young Mariners Base (HYMB) offers engaging primary school trips and secondary school educational visits with an exciting range of outdoor learning opportunities.

The centre offers hands-on team-building games, and water activities that will boost students’ problem-solving skills, such as stand-up paddleboarding and dinghy sailing.

The site’s position on a London transport link makes it ideal for day trips from London, and those looking for school trip ideas and things to do in Hertfordshire will find an array of watersports and land-based activities on offer.

Children will have the chance to take part in caving and climbing experiences that will challenge them both physically and mentally. Pupils can test their hand-eye coordination by aiming for the bullseye on an archery target, or learn the difference between a canoe vs a kayak on a trip along the River Lee (also known as the River Lea).

HYMB is certified by the Adventure Activities Licensing Authority, as well as Adventuremark and Learning Outside the Classroom. The site is also a member of a number of professional bodies, including British Canoeing, the Royal Yachting Association and British Mountaineering Council, as well as the Duke of Edinburgh Award.

By road: The base is located 1.5 miles away from junction 25 on the M25. Free parking is available on site for all users, but this can get busy during peak hours.
