I have a Aussie Sheppard and he loves the lake. Havasu is Dog friendly with dog runs on the Island park and Marina's. We also have several beach spots south of the Island that are safe swimming areas and he loves the water. Have fun...........

Probably a bit less during the week. The amount of people during mid week in early April was moderate.

I'd rent a car. You'll also be better off with one once you are in LH. Have fun!

Bertha C, I used to work for the Az Dept of Environmental Quality There were repeated issues in the mid 1990's involving bacterial blooms in the bay just south of the 'London Bridge'. We did a comprehensive study with a grid of gps located sampling points for water temp and bacterial analysis, backed up by a flyover of one of NASAs themal imaging planes Long story short, we found serious issues between sewage leaching from cesspools (not from the hotel but from one or two smaller public restrooms) on the 'island' (really a sand bar that the water can pass through) , human waste from swimmers, poor water flow (under the bridge) and high water temperatures. I would never swim there, much better to take a boat to a distant beach or deeper water for swimming. I am sure the locals will call me a liar because they want your business at the bars

I have experienced Crazy Horse campground May 5th and extrapolate the same for other major holidays. Crowds of drunk, rude and loud people will be uncontrolled by management or police. It is the reputation of the campground. Reserve at least 3 spaces and party in between to prevent conflicts with shady neighbors. Mobs rule there.

There are Rv parking, and I’m sure they would rent by the month

I have been wondering the same thing. I decided to go with the weekend after.

Don't know.

Yes..lots of water activities

Yes.several. Havasu Falls is a backpacking adventure . It takes 10 hours and a drop of over 2000 feet into the Grand Canyon. Be sure you do your research.
