The versatile Selli-Sillaotsa study trail, which winds through bogs, forests, and gravel roads, is located in the Alam-Pedja Nature Reserve. The beginning of the study trail runs through a pine forest to the edge of the Laeva Bog, where you will find the 12 m high Suuretüki observation tower offering great views. The trail continues along a boardwalk (the width of the boardwalk covered with netting is 47 cm) and along a dirt track through a bog of different levels of development, which is also known for its good cranberry picking spots. 3.5 km of the trail runs in the forest and swamp and 1.2 km on a gravel road. The trail has 11 information boards, two toilets, and two shelters. The length of the trail is 4.7 km.
