The signature run in Varna is the waterfront area, combining a path along Varna Beach, and the beautifully landscaped Primorski Park right above the beach. Run the promenade & park separately, or do the promenade out and the park path. Either way, it’s about 4 km each way. The beach is also runnable!
Waterfront Path & Road. The main road, Крайбрежна алея, runs along Varna Beach for 4 km from the Amusement Park/Swimming Pool in the south to Hidden Beach in the north. There are great views of the beach, Varna Bay, and the Black Sea. It’s a mix of dedicated waterfront path, cycle path, and sidewalk. Toward the northern end it’s just the road, but it’s safe for running.
Primorski Park. This waterfront park sits right above the beach. It’s Varna’s major green space, with wide promenade paths, landscaped gardens, a zoo, science museum, & other attractions. It’s wonderful for running. Create your own route on the numerous paths. Be sure to include the wide, 1 km promenade path between the Heritage Museum and the Pantheon/Rosarium. There are numerous roads & paths through the park to create your own route. Overall, it’s ~4 km north-south.
A great run would be the waterfront path one way the the park back. Overall, about 8 km.
