The number of places you can start seeing is as countless as the summer is short. The bravest tourists take months for trekking, if they wish to explore everything by foot. The best way is cooperation with local tour agencies, it will save time, but not money.

excursions
There are two types of day sightseeing one can practice in Kamchatka. First one is within a reach by auto and walk for $80 at max, the second is about taking a helicopter and costs up to $900. The tour agencies are of no lack in number, so it is rather easy to find them or/and join a group of tourists. Preliminary order of participation in helicopter excursions is better because of the possible crowds in peak season.
