Oh I forgot to comment on fishing:
Casual fishing is everyone's lifelong right in Estonia, but there are restrictions. You can only use a simple fishing rod, the line can't be longer than 1,5 times the fishing rod and you can only use a single hook. That means no reels, double or triple hooks. Fly fishing is not casual fishing.
If you want to use any other form of fishing (including fly fishing) you need a permit. Luckily they can be bought with a phone, so make sure to pick up at least one disposable SIM card at the supermarket.
1 day is 1 euro with the code 400, a week is 3 euros with the code 401.
You just call to this number: 1322*permitcode*IDcode
Foreigners can insert their ID code using 0birthdate0000. So if you were born on the 20th of March in 1970, and want to fish for a week you just call: 1322*401*07003200000
First the year, then the month, then the day.
To prove you've bought it you just need to have some ID on you.
Or if you have a credit card just call 11800. There's additional calling fees though.
