Just off the bottom of Jericho Lane .... You can park looking out to the river and its free

No not at this time.The park,or at least part of the original area was a small inland creek and formed a well stocked fishery that provided an abundance of food for a variety of predator creatures and no doubt that included otters amongst them. Medieval documents record the name Otirpul or Oterpol,Otir being old English for Otter.So from this observation,one can only assume,the largest population of creatures inhabiting this area where indeed otters,so hence the name stayed attached to the area.

That's alrite to come with boots but u also have a nice waking path or joggers way just adjacent to the park.But yes if you are on the fare and specially spending more of your time in park then you should,specially on a rainy day. ta

No camping in Otterspool or anywhere in Liverpool as far as I know. Sue

If it is the Fusion festival then just checked the website. Small bottle of sealed water allowed but no food or alcohol allowed, will be confiscated at the gate. It states that there are food outlets within, hope this helps.

There is parking available but not really sure whether you can overnight. Personally I would not overnight here as you would leave yourself open to undesirable elements, there maybe scope at The Albert Dock where security should be better, good luck.
