Less experienced walkers and cyclists will have more events to pick from in the Lewes Hike and Bike Festival this year.
Extra walks and rides have been added to the programme to meet demand.
New to the festival are history walks around Lewes led by well-known local guide Kevin Gordon.
The route takes in some of the quirky corners of Lewes, including a couple of graveyards (one with Jack the Ripper connections) and twittens.
The Lewes History walk will last about 90 minutes and cover two miles.
Another new walk, organised by Sustrans and Natural England, explores the history and wildlife in the Nature Reserve on Mount Caburn.
Festival spokesperson Brian Deval said: “The walk will include the ancient Bronze Age hill fort and Caburn’s speciality – beautiful orchids, including fragrant, pyramidal and the rare burnt-tip.
“If conditions are good walkers will have the opportunity to see as the buzzards and kestrels soaring with the hot thermals of the southern slopes of the hill.”
Less experienced outdoor enthusiasts will be able to take a beginners course in compass and map reading.
The course, led by experienced climber and instructor Steve Ranger, will teach the principles of navigation and outdoor safety.
The evening programme includes a discussion “Trekking and climbing in Nepal”.
Abhi Rai, a Nepali mountain guide, will discuss the culture, scenery and challenges of the Himalayan kingdom.
The Lewes Hike and Bike Festival (Tuesday May 27 to Saturday May 31) celebrates the beautiful scenery of the South Downs National Park and the historic county town of Lewes with rides, walks and talks.
