Bolu is a lovely city between Ankara and İstanbul with lofty mountains, thick forests, lakes and streams. The breathtakingly beautiful Yedigöller (Seven Lakes) National Park is one of the gifts of nature to Bolu. Lying 42 km north of the city centre, the Park is named after seven large and small lakes formed by landslides. The lakes and the surrounding green area is an ideal escape from the hustle and bustle of the city. Nature lovers can enjoy the tranquillity of the view of the monumental trees, bubbling waterfalls, hiking trails and picnic areas. The mesmerizing beauty of its nature and the rich flora and fauna makes the park a heaven for photography lovers. Another popular and relaxing resort is Lake Abant Nature Park which is set in lovely alpine surroundings at an altitude of 1500 meters, 34 km southwest of the city centre. Offering many opportunities for visitors to enjoy a perfect day in nature, Lake Abant is charming in all seasons. Picnicking, camping, fishing, hiking, horseback riding and cycling are some of the outdoor recreation activities. A walk around the lake is a great chance for capturing beautiful moments especially in winter when the surrounding pine forests are covered with a snow blanket and the lake is frozen. The summer months are the ideal time to explore the endemic species of the park area while the spring time heralds the blossoming of the yellow and white lotus flowers on the lake. 38km from the city centre is Kartalkaya Ski Centre amidst the picturesque pine forests of the Köroğlu Mountains. Ideal for Alpine skiing, ski touring and crosscountry skiing, this resort is well equipped and offers skiing opportunity from late December until the end of March. All the hotels have first aid facilities and medically trained personnel.
