Harmonic Hills/Scenario Guide

Remember:

The Scenario Guide below is only a suggested strategy for completing this scenario—it may not work for all players.
The General Scenario Guide and Hints and Tips articles may also provide helpful information in completing this scenario.
There are usually multiple strategies to successfully completing a scenario; these can be discussed on the scenario's discussion page or written down in an existing or additional section of this article.

Even if you know what to do, this scenario will not be easy. To get started, build a medium-intensity roller coaster, a Merry-Go-Round, and an Information Kiosk. Set your research funding to maximum and direct your priorities to Shops and Stalls until the Toffee Apple Stall and Drinks Stall are researched, then direct your priorities to Roller Coasters and Thrill Rides. Unless you are charging a gate fee and are planning to build evenly throughout the park, disconnect the path to the back area of the park until you have at least 400 guests and need the extra space.

You start out with only three rides and the research of new rides is limited, as you'll realize. With this in mind, try building pretty much every single ride you get, since that, even doing so, there won't be much variety in your park when you reach October, Year 3.

When building roller coasters, always start by analyzing where you're going to put the station and how are you going to connect the entrance and exit to your main path, since the station should be placed in a long stretch of land with no trees. Also, choose the type carefully. Certain varieties (e.g. Steel Mini, Virginia Reel, and Steel Wild Mouse) do not need very large slopes to have good excitement ratings provided the rest of the design is adequate. The ability for the Vertical Roller Coaster to tunnel underground using vertical track also helps to overcome the height restriction, although it requires care in use to keep the trains from stalling out as they rise back above the ground. Although you shouldn't expect rides to be very exciting here, aim for an excitement rating of 4.50 from the Steel Mini Roller Coaster and 5.00 from other roller coaster types. However, it should be quite feasible to design coasters with excitement ratings around 8.00, especially with the Virginia Reel and the Steel Wild Mouse — both can have pretty high excitement ratings with a somewhat simple track, considering that these coasters are some of the best options you have to build around the trees.

If you have not yet completed Rainbow Valley from the original pack, consider doing so to prepare yourself for this scenario. You may still struggle with the height restriction, but you will be more prepared to deal with the tree removal and landscape adjustment restrictions you will face here.
