Croatia Tourism describes the Dalmation Coast as "The Mediterranean as it Once Was" and it really feels like just that. The multitude of walled towns from the most famous Dubrovnik in the south all the way up the coast including Trogir, Korcula, Split and Primosten and will leave you spellbound.
The sailing in Croatia is great too - with so many islands the sea is seldom rough and with so many places to visit short trips of 2-3 hours sailing per day on the crystal clear waters is very normal.
Sailing holidays in the south of Croatia typically start in Dubrovnik and days are spent island-hopping through the national parks of Miljet to the upmarket glitz of Hvar and the remote magic of Vis and Bisovo. The central coast has fewer islands but great towns such as Primosten, Sibenik and Vodice - and of course the Krk National Park that involves sailing 5nm inland to anchor at Scradin before taking the small ferry up to the watefalls and bush walks. The north is another mix of islands and mainland sailing including the famous Kornati National Park and ancient town of Pula.
