Road to Citadelle one way:
- Local bus (taptap) from Cap Haitien to Milot: 45 min, 20 goud (=20 RD pesos). In CP take a motoconcho to the taptap-station, 25 goud.
- Motoconcho from Milot to touristoffice of Citadelle: 30 min, 200 goud one way.
- Walking from office to Citadelle: 1 hour, hard, awesome landscape, 200 goud entrance to pay at the touristoffice. You don't need a guide, good road.
For return to Milot be sure the motoconcho has good brakes.
I recommend the hotel Roi Christophe in Cap Haitien. Its worth the 100 US$. And you have a nice pool after the trip to Citadelle
Trip to Labadee: first taptap 30 min, 25 goud. Then boat to the village, 10 min, 10 goud. The taptap-station in CP for Labadee is not the same one as for Milot.
The motoconchos in CP cost 25 goud, also nights.
