Went for a short trip in Meiko, Kirkkonummi, Finland.
Only 30 minutes from Helsinki, very easy to find and well marked routes.
3 Main routes:
Meiko round 8 km.
Kotokierros round 4.4km.
Kuikankierros round 3.7km.
Couple of firespots to take a break.
Easy access all year long, trails open without maintenance due to amount of people visiting.
