Eureka is a private members club open from 11am, 364 days of the year. Located in Kent, the ‘Garden Of England’, Eureka certainly lives up to this reputation with its 23 acres of beautiful landscaped lawns, fields and woodlands where you can relax and laze around the tranquil grounds, or take a stroll through the peaceful woods.

There is free onsite parking, accommodation available, a newly refurbished club with a large dance floor, licensed bar and rest areas. Also, a wet area featuring one 8 person and one 4 person jacuzzi, sauna and showers.  Outside there is a 60ft x 30ft swimming pool (during the  summer), huge sunbathing fields and walkways through the wooded area.
