Trevassack Lake

Hidden just ten minutes from Helston, a few miles south of the Helford River, a hive of accessible activity is bubbling away in the privacy of a springwater-filled quarry...

Off a quiet country lane, it’s a jaw-dropping moment as Trevassack Lake reveals itself, leaving locals wondering why they’ve not been before and holidaymakers coming back for more. Welcome to a community hub of watersports, holidays, events, and the dog-friendly lakeside café—open to everyone!

Activities & Experiences

Owned by Cornish charity Children’s Sailing Trust, the activities are run by CST Experiences; sailing, paddlesports, wild swimming, events and venue hire for birthdays, group meet-ups, and even accessible weddings with well-being classes such as yoga and pilates held in the lakeside function room. The site is Gold award-winning for Accessibility and Inclusivity, being entirely wheelchair and SEND-friendly, including the water!

Trevassack Holidays

Just a stone’s throw from the water, Trevassack Holidays is CST’s exclusive collection of six accessible holiday properties, all with hot tubs set in their deck. Stay a few days and enjoy sunsets over still waters, or book longer and take lessons to earn an RYA qualification—guests get 15% discount on watersports.

The Trevassack Lake Cafe

The cherry on the lake? Trevassack Lake Cafe where you can enjoy a little TLC with artisan coffee and homemade cakes, indulge in gourmet brunches and daily specials all cooked-to-order with a view. Open 7 days a week to the general public, you can sit inside and dine, eat al fresco on the lakeside deck, or brunch at a picnic table on the beach. You’ve just found your new favourite eatery beside the ‘secret’ lake, where all profits support the charity.

Support the Charity

As a not-for-profit organisation, visiting Trevassack helps support the work of the charity set up by John Green MBE in 1997. He wanted every child to experience the freedom of sailing on the Helford River - that glorious, life-affirming feeling of carving paths through open water, tacking and gybing with a twitch of the rudder. Now, thousands of children have taken the helm, working towards their RYA accreditations with pride on both the river and the lake.
