The Viper is one of Essex's many little gems pub-wise. It's set all alone in woodland but serves real ale, excellent food and a little beer festival over the August Bank holiday (Jake the Snake is the pub's resident tipple but there are other goodies on tap during the festival). Ingatestone is only about fifteen minutes' drive from The Viper so something to see stone-wise on the way there or on the way back.
For those who can't make it to the Avebury Megameet maybe we'll catch up with you at The Viper instead (or as well : -)
