....aaaaand we are back in the water also this year!!! Kayaking around the city channels is one of the most enjoyable activities in Copenhagen on a sunny day. GreenKayak, a NGO dedicated to raise awareness to ocean pollution, makes few (open) kayaks available across the city to paddle and help collecting waste floating in the water. Open kayaks are typically easier to manovre than other types, and do not require EPP2/EPP3 patents. I booked 2 double kayaks for 4 ppl in total. It is possible to use the facilities at Kayak Republic free of charge: restrooms, lockers and showers. **REQUIREMENT** \- Safety first \- Need to be able to swim comfortably \- Waterproof gear preferable \- Sun lotion and sunglasses \- Change of clothes in case yours get a bit wet during paddling \- Towel\, if you want to shower or just in case **COST** Unfortunately, due to the frequent last minute cancellation last summer, it was challenging backfilling participants with short or no notice, and it was very disrespectful to the group and GreenKayak NGO. **To reserve your spot, please transfer 150 kr. to my mobilepay 25717293**. The amount will be returned to you if you show up on time, or the event is cancelled for other reasons; **this remains a free non-profit event**. The kayak rental is free of charge provided that: \- we are able to pick\-up some waste during our paddling activity \- we share our experience on the So\.Me \#GreenKayak **AGENDA** 11:50- Meet up - please be on time 🙂 11:50-12:00 Briefing and getting ready 12-00-13:45 Paddling around Copenhagen channels and return to the start point 13:45-14:00 Return the equipment to Kayak Republic **DISCOMFORT LEVEL** \- 3/5 **TO LEARN MORE** [GreenKayak](https://www.greenkayak.org/)

Malmö has a nature reserve in the city! However it can only be accessed with a guide from Malmö stad. You'll need to reserve your spot for the tour by buying a symbolic ticket via this link: [https://www.kulturcentralen.nu/evenemang/limhamnlimestonequarry-joinaguidedtourinenglish](https://www.kulturcentralen.nu/evenemang/limhamnlimestonequarry-joinaguidedtourinenglish) It costs 10 kr. Note that the sale opens one month before the event, on April 24th at 9am. Make sure you pick the right date (May 24th). Spots sell fast, so if you are eager to join, make your reservation early in the day. Since it's a public tour I have no idea how many spots are available. It's first come first serve. The reserve comes with restrictions. One of them being: it is not allowed to walk or stay outside of the assigned paths and areas. Another being: it is also not allowed to bring pets or drones and other aircrafts. After the tour, for those who are interested, we can walk around the quarry, it's 4km. There are viewpoints with nice view of the area, see featured photo. The tour lasts for 2 hours. The duration of this event is including the walk around the quarry. Limhamns kalkbrott has been a nature reserve since 2011. It used to be a mining area, but nature has been roaming free since 1994, when the operations closed down. What to bring: water could be good, and also sunscreen. Dress according to weather. How to get there: The quarry is easily accessible by bike. Public transportation: City bus 12 arrives at bus stop Sibbarpsvägen at 14.39 from the north. From there it's a short walk to the meeting point and gate. By car: There's a parking lot by the gate to the reserve and our meeting point. Note that the **gates** for entering with the guide **close** at 3pm **SHARP**. Come early!

End time is approximate, let's take our time to enjoy the sounds of this rare toad, and views of Lomma bay from the shoreline. Please change your rsvp as soon as possible when you have decided to no longer attend. In Malmö there are two thriving locations with this otherwise rare species. May is the time for the European green toad to mate. We will keep our ears out for their calls. On this event we will meet in Oljehamnen in the vicinity of bus stop Svartögatan, go for a walk along the shoreline, enjoying the views of Lomma bay, and reach a place called Paddeborg, a pond where these toads are supposed to hang out, to enjoy their song. Perhaps even catch a glimpse of them. When we are satisfied after sunset we will head back to the bus stop. What to bring: 🐸 something to sit on 🐸 water for the walk 🐸 dress according to weather 🐸 patience and silence Getting there: By bike: Meeting point is accessible by bike from Malmö Central Station.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.
